Feilden Clegg Bradley Architects LLP
1. The core buildings are of international significance. The<br />
Main Mill is the flagship and is the oldest iron framed<br />
building in the world. Redevelopment of the site must be<br />
to the highest standards.<br />
2. The significance of the building is difficult to appreciate<br />
due to the adjacent land uses, the absence of the canal<br />
and the lack of accessibility.<br />
3. The historic buildings are elegant and innovative pieces<br />
of structural engineering however their unique design<br />
presents important limitations to the acceptable range of<br />
re-uses.<br />
4. Whilst empty for 15 years, the repair costs have<br />
escalated, and the building is at the highest category<br />
within English Heritage’s Buildings At Risk register.<br />
Urgent action is required to safeguard the long term future<br />
of the buildings.<br />
5. There is very limited scope for any enabling development<br />
near the historic buildings, and a new vehicular route<br />
would need to be created to service this. It is considered<br />
that the best new route would be through the bus depot<br />
site.<br />
6. Any scheme for redevelopment would be expensive and a<br />
significant conservation deficit exists within all potentially<br />
acceptable options. The input of public funding must<br />
deliver public benefit.<br />
0.2 Executive Summary<br />
This document presents the following key observations and conclusions about the Ditherington Flax Mill site:<br />
7. The site would best suit a mix of uses which encourages<br />
a range of users, including residential, retail, leisure and<br />
perhaps a community facility.<br />
8. The redevelopment of the site offers a significant<br />
opportunity to focus community interests and act as a<br />
focus for wider regeneration of the Ditherington area.<br />
9. Improvement of the Spring Gardens site is an essential<br />
step to improving interpretation and amenity of the site.<br />
10. There is an opportunity to interpret the line of the<br />
<strong>Shropshire</strong> Union canal and new build should not<br />
prejudice its future reinstatement.<br />
11. A number of potential developers have expressed an<br />
interest in the site. However it must be noted that the<br />
re-use of the core buildings is likely to require a special<br />
approach.<br />
12. During the next stage of work it will be essential for<br />
the proposals to be developed by a strong team in<br />
partnership with a range of funding stakeholders.<br />

Introduction<br />
This document provides a summary of the work undertaken by<br />
a team lead by Feilden Clegg Bradley Architects as part of a<br />
Masterplan Study exercise for the Ditherington Flax Mill project. It<br />
presents an explanation of, and background information to, the<br />
12 key points which were presented to <strong>Council</strong>lors and the local<br />
community on the 17th and 18th May 2004.<br />
It has been recognised for some time that the site, which is<br />
acknowledged as being of international historic significance, has<br />
been in urgent need of major investment for many years and<br />
that the solution is likely to include the need for significant public<br />
funding contributions. This study is a result of English Heritage’s<br />
desire to see a sustainable solution implemented through<br />
partnership with other key organisations inlcuding Shrewsbury &<br />
Atcham Borough <strong>Council</strong> and Advantage West Midlands.<br />
Team for the Study<br />
0.3 Introduction<br />

The Brief for the Study<br />
The key aims of the <strong>masterplan</strong> study have been:<br />
To explore options for the development of a strategic vision for<br />
the site.<br />
To work in partnership with English Heritage and the Borough<br />
<strong>Council</strong> officers.<br />
To seek to identify a preferred option for redevelopment by the<br />
end of April 2004<br />
The brief for the study describes the client group’s aspirations for a<br />
Masterplan that will create:<br />
A vibrant and accessible mix of active uses<br />
A site which attracts both public and private investment<br />
An enhanced understanding of the site and its significance<br />
A beacon for high quality regeneration<br />
A secure and attractive place<br />
The highest standards of architectural design for new work<br />
The study has been undertaken in two distinct phases as follows:<br />
Stage 1: ‘Information Gathering’<br />
This work included an assessment of the current conditions<br />
affecting the Flax Mill site including its development history,<br />
historical significance, market context and structural condition.<br />
This work was mainly undertaken between November 2003 and<br />
January 2004.<br />
Stage 2: ‘Option Appraisal’<br />
This work included assessment of a broad range of options in<br />
order to consider the potential future character of the site, including<br />
an assessment of development costs. This appraisal work was<br />
mainly under taken between January and April 2004.<br />
Other Documents<br />
0.3 Introduction<br />

Masterplan Study Team during the course of this study:<br />
Property Market Appraisal Towler Shaw Roberts<br />
Structural Overview Alan Baxter & Assocs<br />
Desktop Contamination Study ESI<br />
Costs Dearle & Henderson<br />
As of the commission from English Heritage, we have also<br />
prepared a Conservation Plan for the Ditherington Flax Mill site.<br />
The Conservation Plan considers the historical development of<br />
the site in more detail, describes the significance of the site, and<br />
proposes specific conservation policies to assist in managing<br />
change. It is an important document which should underpin<br />
proposals that are likely to affect the historic core of the site.<br />
Bibliography & Contacts<br />
During the course of the Study we have reviewed a very wide<br />
range of information about the buildings and made contact with a<br />
number of interested parties who have expressed an interest in the<br />
future of the Flax Mill site.<br />
A full list of contacts and sources of reference for our work to date<br />
is set down at the end of this report.<br />

1.0 The Study Area<br />
Feilden Clegg Bradley Architects LLP
Location Plan of Site<br />
May 2004<br />
1.1 General Description<br />
The Study Area comprises a group of sites approximately 1 mile<br />
north of Shrewsbury town centre at Ditherington.<br />
The site is hemmed in by the Shrewbury to Crewe railway line to<br />
the west and the busy Spring Gardens road to the east, which<br />
provides a main route to and from the town centre.<br />
The site is in a mainly residential area of the town and is<br />
surrounded by a mix of housing accomodation dating from the<br />
early 19th century and mid to late 20th century.<br />
Along Spring Gardens is a range of typical ‘edge of town’<br />
businesses, including building materials suppliers, take away food<br />
outlets and other small businesses. A bus station, operated by<br />
Arriva, is located immediately north of the site.<br />
Feilden Clegg Bradley Architects LLP
Key Historical References<br />
The development history of the site and its historical significance<br />
has been established through a series of important historical<br />
appraisals and essays which have been written over the past 50<br />
years or so. The key documents we have referred to during the<br />
course of the study are as follows:<br />
The First Iron-framed Buildings<br />
Prof. Turpin Bannister, Architectural Review (April 1950)<br />
This essay begins to prove that the Flax Mill at Ditherington<br />
is the world’s first iron-framed building. In doing so, Bannister<br />
challenges the belief that it was Salford’s Cotton Twist Mill.<br />

May 2004<br />
A brief summary of the development history<br />
On 20 September 1796, <strong>flax</strong> spinners John Marshall and Thomas<br />
and Benjamin Benyon purchased the site which lies on the<br />
northern outskirts of Shrewsbury for the construction of a purpose<br />
built Flax Mill. Expertise for the design of the buildings was<br />
provided by Charles Bage, who joined as a minor partner. The<br />
resulting complex of buildings, which include the oldest surviving<br />
iron framed building in the world are widely recognised as being of<br />
International significance. The Main Mill was the largest building<br />
of its kind ever built, and it led the way in terms of structural<br />
engineering, working methodology and power consumption. Other<br />
buildings included an Apprentice House, Hackling Mill (Cross Mill),<br />
Warehouse, Dye House and Offices, all of which still survive. By<br />
1797 a complex of buildings had been completed and operations<br />
had begun.<br />
The company fell into liquidation in 1886 and the buildings were<br />
converted to a maltings by a local entrepreneur, William Jones.<br />
Major modifications were undertaken; includingextensive adaptions<br />
to the main mill (extending the area available for floor malting) and<br />
the addition of the malting kiln.<br />
William Jones and Sons went bankrupt in 1934 and the business<br />
was subsequently administered by the Alliance Insurance<br />
Company, who in 1948, handed over the works to Ansells, the<br />
Birmingham brewery, part of Allied Breweries Ltd. For a short time<br />
during the Second World War, the buildings were used as an army<br />
barracks.<br />
Malting ceased at Ditherington in the summer of 1987 and the<br />
building has remained empty since. Following an unsuccessful<br />
attempt to redevelop the site in the early 1990s, the former Flax Mill<br />
site was purchased by Maltings Developments Ltd. The company<br />
achieved Planning and Listed Building Consent for a mixed use<br />
scheme in 2000 however this scheme has not been realised.<br />
1.2 Development History<br />
A brief summary of the planning history<br />
Since the vacancy of the site in 1987, the planning history of the<br />
site has included the following key events:<br />
Planning Permission 1:<br />
Approved in May 1990 for conversion to offices, light<br />
industry, workshops, leisure, exhibition space and museum.<br />
This application also included a scheme for road junction<br />
impovements.<br />
Planning Permission 2: (Maltings Development Ltd)<br />
Approved in February 2000, following the signing of a Section<br />
106 Agreement. The scheme consisted of a conversion for<br />
mill shopping, offices, Arts Trust use and residential. It also<br />
included reinstatement of the former canal and landscaping<br />
works to form a new site entrance.<br />
Major previous grant award offers to Maltings Development<br />
Ltd from English Heritage (£0.5m) in 1999, and English<br />
Partnerships (£2.8m) in 2000 to assist development. Both<br />
since rescinded.<br />

1.3 Ownerships & Tenancies<br />
For the purposes of this Masterplan study, the sites in the<br />
possession of the present owners (ie sites A1, A2 and A3) and all<br />
areas surrounding the historic mill buildings have been considered.<br />
The illustration highlights the various current ownerships and<br />
tenancies which surround the ‘core area’ of the site.<br />

An exploratory meeting to discuss the future of the bus depot<br />
was held between representatives of Arriva, SABC, FCBA and<br />
Towler Shaw Roberts at the offices of SABC on 8th April 2004.<br />
The meeting was constructive and concluded that the feasibility<br />
of relocating the bus depot should continue to be assessed jointly<br />
during a later phase of the Masterplan Study.<br />
Negotiations with other landowners have not taken place as part of<br />
the work undertaken to date.<br />

Local Plan Policies<br />
1.4 Planning & Regeneration Framework<br />
Following a public consultation, the Shrewsbury and Atcham<br />
Borough <strong>Council</strong> approved an extension of the Shrewsbury<br />
Conservation Area to include Castlefields and Spring Gardens.<br />
The designated area includes the site of the Flax Mill.<br />
As a Listed Building located within the Urban Area of Shrewsbury<br />
set within the Shrewsbury Town Centre Conservation Area, the<br />
following Local Plan Policies may affect any redevelopment of the<br />
Flax Mill.<br />
HE5: Alterations to Listed Buildings<br />
Policy HE5 seeks to ensure that any proposals for alterations<br />
to any Listed Building do not adversely affect its architecture or<br />
historic character. The policy also requires that full information is<br />
available to assess the impacts of any proposals and that a high<br />
standard of design is maintained.<br />
HE6: New Uses for Listed Buildings<br />
This policy requires that the applicant demonstrates that the<br />
proposed use and any consequent alterations will not detrimentally<br />
affect the structure, character or setting of the building.<br />
HE7: Development Affecting the Setting of Listed Building<br />
This policy serves to protect the setting and important views of<br />
listed buildings.<br />
HE8: New Development in or Adj. to Conservation Areas<br />
Policy HE8 seeks to ensure new development enhances or<br />
preserves the character of a Conservation Area and requires that<br />
full details of design and materials and landscaping are submitted.<br />
The policy also seeks to:<br />
- protect views and vistas from outside the boundary of the<br />
Conservation Area.<br />
- avoid the loss of open space, landscaping features, trees or<br />
hedgerows that are important to the character of the area.<br />
- and avoid generating inappropriate levels of parking and traffic<br />
generation or environmental problems.<br />
HE9: Demolition of buildings in Conservation Areas<br />
This policy will be relevant if any demolition is considered as part<br />
of a proposal and seeks to ensure that only demolition that will<br />
have a positive impact on the character and appearance of the<br />
Conservation Area will be granted.<br />
HS2: Residential Development on sites within Shrewsbury<br />
not allocated under policy HS1<br />
This policy will be relevant if the site is proposed for residential<br />
development. The development should not result in the loss of<br />
any open space and should not have a detrimental impact on the<br />
existing residential amenity.<br />
HS8: Affordable Housing in the Urban Area of Shrewsbury<br />
It should also be noted that an element of affordable housing will<br />
normally be required as part of a residential redevelopment.<br />
Apart from the key policies set out above there are a number of<br />
policies, which relate to car parking, transport and infrastructure<br />
which will need to be considered. Depending on the end use for<br />
the Flax Mill retail and leisure and open space policies may also<br />
apply.<br />

in Autumn 2003.<br />
1.5 Recent Developments<br />
Under Section 54 of the Planning (Listed Buildings and<br />
Conservation Areas) Act 1990, a Local Authority is enabled to carry<br />
out necessary Urgent Works for the preservation of listed buildings<br />
in their area, after giving appropriate notice to the owner. These<br />
powers can be used only in respect of an unoccupied building, or<br />
the unused part of a partly occupied building.<br />
Planning Policy Guidance Document PPG15 – Planning and the<br />
Historic Environment advises that:<br />
‘[Local] Authorities will note that these powers are confined to<br />
urgent works: in the Secretary of State’s view, their use should<br />
be restricted to emergency repairs, for example works to keep<br />
a building wind and weather-proof and safe from collapse, or<br />
action to prevent vandalism or theft. The steps taken should<br />
be the minimum consistent with achieving this objective, and<br />
should not involve an owner in great expense.’<br />
In Autumn 2003, a programme of such Urgent Works to restore<br />
the weather proof nature of the buildings was started on site.<br />
The schedule of work was overseen by Peter Napier for English<br />
Heritage and Shrewsbury & Atcham Borough <strong>Council</strong>. The works<br />
were completed in March 2004.<br />
Following the completion of the works, a subsequent Repairs<br />
Notice was served on Maltings Developments Ltd on 21 April<br />
2004.<br />
May 2004 Feilden Clegg Bradley Architects LLP
In addition to the historical documents referred to in section 1.1,<br />
a broad range of information relating to the site was also received<br />
and reviewed during the course of the Study including from the<br />
following sources:<br />
English Heritage<br />
Shrewsbury and Atcham Borough <strong>Council</strong><br />
Maltings Development Ltd<br />
National Monuments Record<br />
<strong>Shropshire</strong> County Archives<br />

An inventory of the main documents is set down in Appendix 2.<br />
The Conservation Plan, produced by Anthony Blacklay and<br />
Associates for Maltings Developments Ltd, is also noteworthy as<br />
a fairly comprehensive document which contains a good deal of<br />
useful information about the site and its future development. It is,<br />
however, a rather complicated document which has been written<br />
(at least in part) to justify the particular approach adopted by the<br />
Maltings Development Ltd scheme in 1999, rather than taking a<br />
fully impartial view on the site.<br />
1.6 Information Available<br />
Clearly a good deal of supplementary information would be<br />
required as part of a scheme for redevelopment. Of particular note<br />
are the following:<br />
a detailed survey of all of the buildings on the site<br />
a schedule of existing fixtures, fittings and equipment<br />

2.1 Context<br />
The site has a different boundary condition<br />
on each of its main sides and a range of key<br />
spaces within the site, including some areas with<br />
development potential, albeit limited.<br />
The photographs on the following pages provide<br />
an overview of the site and the range of spaces<br />
therein.<br />
2.1.1 Southern Boundary<br />
The existing main access to the site is from a road<br />
serving a modern residential development to the<br />
south known as Marshalls Court.<br />
The boundary wall to the site consists of a 2-<br />
3m brickwork wall, which includes sections of a<br />
number of former buildings on the site.<br />

2.1 Context<br />
2.1.2 Western Boundary<br />
To the west, the site is contained by a historic<br />
brick retaining wall, which provides an elevated<br />
outlook across a pathway (Greenfields Lane), the<br />
railway embankment of the Crewe to Shrewsbury<br />
railway line, and Greenfields Park playing field<br />
beyond. This open aspect provides particularly<br />
important long views to the site from the west.<br />

2.1.3 Northern Boundary<br />
To the north, the site is separated from the back<br />
gardens of a 1920s housing estate (Wingfield<br />
Close) by a combination of a historic brick wall<br />
to the north west, (incorporating the former gate<br />
piers to the railway siding entrance), and more<br />
modern fencing to the north and north east.<br />
A bus depot and social club operated by Arriva<br />
are located to the north east of the site.<br />

2.1.4 Eastern Boundary<br />
To the east, the site overlooks a range of modern<br />
small scale businesses which separate it from<br />
the busy Spring Gardens road. Properties here<br />
include a Buildiers Merchant, a Chinese Takeaway,<br />
a Glazing Supplier and a Garden Building Supplier.<br />
These businesses partly occupy the former site of<br />
the <strong>Shropshire</strong> Union Canal, which ran along the<br />
eastern boundary of the Mill site.<br />
Whilst most are modern structures, they also<br />
include two Victorian brick houses which are part<br />
of the former Haughmond Square.<br />

2.1 Context<br />
2.1.5 North Site Area<br />
Within the site itself, the buildings are grouped towards<br />
the southern end of the site. At the northern end of the<br />
site, demolition of earlier buildings has created potential<br />
space for new development between the Apprentice<br />
House and the rear gardens of Wingfield Close.<br />
It is known that this area was the site of a number<br />
of earlier buildings and further investigation of<br />
archaeological and contamination issues would be<br />
required prior to development.<br />
2.1.6 Views<br />
The views from the roof of the Main Mill give a very clear<br />
indication of its scale compared to that of its context.<br />

2.2.1 Summary of Significance<br />
The FCBA Conservation Plan summarises the significance of the<br />
site and its various elements as follows:<br />
- The Main Mill is of INTERNATIONAL significance as it is<br />
the oldest iron framed building in the world.<br />
- The Main Mill is of INTERNATIONAL significance in view<br />
of its outstanding importance in the development of<br />
structural engineering within the building design.<br />
- The Whole Site is of NATIONAL significance as it<br />
provides a virtually complete surviving example of<br />
a major textile Mill, including its range of ancillary<br />
accommodation.<br />
- The Cross Mill is of NATIONAL significance as it is<br />
believed to be a unique surviving example of a hackling<br />
shop built for a textile mill.<br />
- The Flax Mill Group of Main Mill, Cross Mill and<br />
Warehouse is of NATIONAL significance as it includes 3<br />
of the 10 oldest iron framed buildings in the world.<br />
- The Whole Site is of REGIONAL significance as it is<br />
the only surviving <strong>flax</strong> mill in Shrewsbury (following the<br />
demolition of Bages Mill in Castlefields in 1835 and the<br />
Weaving factory in Kingsland).<br />
- The Whole Site is of LOCAL significance as it is the<br />
only surviving large Maltings complex surviving in the<br />
immediate area (following the conversion of the complex<br />
at Belle Vue and the demolition of Castle Maltings).<br />
- The Maltings Phase is of LOCAL significance due to its<br />
likely association with prominent local figures William<br />
Jones and engineer Henry Stopes.<br />
2.2 Historical Significance<br />
2.2.2 Commentary<br />
At the core of the group is the Main Mill, which dates from 1797<br />
and is recognised as the world’s first ever exclusively iron and brick<br />
structure. Designed by Charles Bage, the Main Mill survives as an<br />
outstanding achievement in the story of the structural development<br />
of industrial buildings. Standing adjacent to it are the third oldest<br />
(the Warehouse) and eighth oldest (the Cross Mill) surviving iron<br />
framed buildings in the world.<br />
The Ditherington Flax Mill as a whole is recognised as a product<br />
of extraordinary ambition and endeavour. The buildings were<br />
the largest <strong>flax</strong> mill buildings in the country outside of Leeds,<br />
and set the standard for contemporary working methodology<br />
within the industry and the scale of powered machinery that was<br />
employed. The development also extended well beyond the site’s<br />
boundary walls to include Apprentices Houses and other workers’<br />
accommodation nearby, much of which still stands.<br />
At the closure of the Flax Mill in 1886, the site was overtaken by a<br />
Maltings operation run by a prominent local entrepreneur named<br />
William Jones and remained in use as a Maltings until its closure<br />
in 1987. The various Maltings businesses occupied the range<br />
of existing buildings intensively and also made some important<br />
changes on the site over time. Most notable are the changes<br />
to the appearance of the core buildings, which include the reconfiguration<br />
of the fenestration of the Main Mill, the addition of the<br />
Maltings Tower, and the addition of the Malt Kiln.<br />
During the site’s period of redundancy of more than 15 years, the<br />
buildings have suffered from the effects of theft, arson, vandalism<br />
and a general lack of maintenance. The overall effect is that the<br />
buildings are in a fairly desperate state of repair.<br />

2.3 Condition<br />
During their period of sustained redundancy since 1987, the<br />
condition of the buildings has deteriorated significantly. It is evident<br />
that they continue to suffer from the effects of vandalism, theft,<br />
arson and weather ingress.<br />
The Apprentice House has suffered particularly badly and has<br />
had most of its historic fittings (e.g. fireplaces) either stolen or<br />
vandalised.<br />
The buildings are classified as category A on the English Heritage<br />
Buildings At Risk Register.<br />
The effects of sustained neglect and vandalism has caused the<br />
site to be considered a notorious problem by a number of local<br />
residents.<br />

2.3.1 Access to the Site<br />
In order to acheive the maximum commerical potential of the site it<br />
is considered that access will need to be greatly improved. There<br />
are physical limitations to the site, both in terms of the proximity<br />
of the buildings, but also by the definition of its boundaries. The<br />
current vehicular entrance to the site (shown as a hollow arrow on<br />
the diagram adjacent), lies at the south corner and is via an already<br />
busy junction with Spring Gardens.<br />
It is believed that a new means of vehicular access to the site will<br />
be necessary to create appropriate access without detriment to the<br />
main core of the site. This can be achieved in two ways:<br />
1. Upgrade the existing footpath to the west of the site to create<br />
an access road that breaks the boundary wall and ramps up to<br />
the level of the Mill Buildings. This is shown as the light dotted<br />
line.<br />
2. Enter the vacant area to the North of the Historic Buildings<br />
directly from Spring Gardens, shown as the heavy dotted line.<br />
2.3.2 Car parking on and around the site<br />
For the same reasons as above, the issue of car parking becomes<br />
fundamental to the consideration of the site for any sort of<br />
commercial activity. The lack of space and the restrictions to access<br />
place heavy restrictions on the quantity and amenity of car parking<br />
spaces. It is believed that areas around and adjacent to the site<br />
could be used as car parking. This would minimise the disruption<br />
to the historic core buildings, and leave areas in the centre of<br />
the site clear to provide space for emergency access and any<br />
neccessary deliveries.<br />
2.4 Access & Parking<br />
The sketch to the left is an exercise illustrating the quantity<br />
of carparking possible if the relative areas remain vacant of<br />
development. However, it is not envisaged at this stage that all of<br />
these areas will be required as parking.<br />

As part of this study we have consulted <strong>Shropshire</strong> County <strong>Council</strong><br />
(SCC) Highways department. In discussion, the following points<br />
were raised as issues surrounding any future developments:<br />
SCC acknowledge that the historical significance and the<br />
physical constraints of the site means that it is highly likely that<br />
some highways design solutions may need to be comprised.<br />
SCC reported that a Traffic Survey/Report had been produced<br />
by Dennis Wilson to support a previous application, However,<br />
they could not release this document due to copyright issues.<br />
A Grampian Arrangement was applied to this scheme, insisting<br />
that no work begins until proposals are agreed.<br />
SCC advised that the potential impact of new development<br />
on the junction with St. Michael’s Street must be carefully<br />
considered. This is already nearing capacity and during<br />
peak hours additional traffic control measures are likely to be<br />
required.<br />
Support would be given for a new access for the North<br />
Site Area at the Bus Depot. This could be acheived by the<br />
addition of another leg to the existing mini roundabout, or<br />
the introduction of a second roundabout in a more suitable<br />
location.<br />
SCC advised that, depending on the end uses proposed, the<br />
need for each parking and drop off areas needs to be very<br />
carefully considered.<br />
SCC confirmed that there had been no initial objections to a<br />
previous proposal to provide a new vehicle access at the rear<br />
of the site.<br />
2.5 Traffic & Highways<br />
SCC confirmed that the upgrading of the footpath to the west<br />
of the site to a road is unlikley to meet with resistance.<br />
SCC advised that the entry and exit points to the Mill site<br />
should be separated. The introduction of a one way system<br />
would reduce the pressure on any existing junctions.<br />

2.6 Contamination<br />
During the course fo the Study, a Ground Contamination Desk-top<br />
Report has been undertaken by ESI. Their report concluded the<br />
following points:<br />
Contact with EA, SABC, Mowlem and Mr Capp during<br />
research.<br />
There is an Aquifer of particular significance. It is of 5-6m<br />
internal diameter, but is currently unused.<br />
Proximity of Bagley Brook (within 75m).<br />
A wide range of potential contaminants due to former uses (eg<br />
gas holders, waste stores, blacksmiths, canal, diesel storage<br />
tanks) is likely to exist.<br />
A main risk is pollution of controlled water.<br />
Further work is needed to establish sources of contamination<br />
and pathways (however at this stage it is not anticipated<br />
that ground contamination will present a signicant barrier to<br />
redevelopment.)<br />
There is further important information held by Mowlems and Mr<br />
Capp (drainage plans and soil test results).<br />

3.3 The Main Mill<br />
Listing: Grade 1<br />
Built: 1797<br />
Total Area (G.I.A): 2750m²<br />
No. of Storeys: 5<br />
Average Storey Height: 3.2m<br />
The main mill is the most important building on the site and is<br />
recognised as the oldest iron framed building in the world. It was<br />
built in 1797 to designs by Charles Bage. The internal structure is<br />
remarkably elegant, however this leads to the requirement for some<br />
remedial repair and restriction over floor loadings in re-use, which<br />
are likely to be limited to 2.5kN/m2 (See ABA report).<br />
During its subsequent conversion for use as a maltings (1886<br />
– 1987), the Main Mill experienced some important changes to its<br />
appearance, most notably the addition of the distinctive ‘Maltings<br />
tower’ at the northern end, and the blocking up of 2 out of every 3<br />
windows. The principle of reinstating the former fenestration of the<br />
Main Mill has previously been granted planning permission and is<br />
an essential feature of some re-use options.<br />
It is considered particularly important to provide publicly available<br />
functions at lower levels in the Main Mill. It is also important to seek<br />
re-uses which would minimise the subdivision of the upper floors,<br />
in order that the spaces may be properly appreciated (e.g. light<br />
office, large residential flats).<br />
The building is connected to the adjacent Maltings Kiln and Cross<br />
Mill at its northern end, and has internal staircases at its northern<br />
and southern ends. The building has particular prominence to<br />
Spring Gardens and its tower and painted hoarding are distinctive<br />
features. A large lean-to building on the east side of the building,<br />
which was built as a maltings floor, has recently been demolished.<br />

3.4 The Cross Mill<br />
Built: 1812<br />
Listing: Grade 1<br />
Total Area (G.I.A.): 1295m²<br />
No. of Storeys: 4 plus Attic<br />
Average Storey Height: 2.8m<br />
The Cross Mill building (or Flax Hackling shop) was built in 1812 in<br />
the ‘fireproof’ manner of the Main Mill but only following destruction<br />
of an earlier (non-fireproof) building on the site in 1811. The<br />
building is Grade 1 listed, is the 8th oldest iron framed building in<br />
the world. The Cross Mill (unlike the Main Mill), has an iron-trussed<br />
roof. The Cross Mill is believed to be a unique surviving example of<br />
a hackling shop built for a textile mill.<br />
The internal structure is similar to that employed within the Main<br />
Mill. Like the Main Mill, it is assumed that the internal structure<br />
would require some remedial repair and that restriction over its<br />
future re-use should be established by a floor loading limit of<br />
2.5kN/m2 (see ABA report). During its conversion for use as a<br />
maltings, the Cross Mill windows were similarly amended.<br />
It is considered important to provide publicly accessible functions<br />
at lower floor levels. It would be desirable to minimise the subdivision<br />
of the upper floors, (as with the Main Mill) however it should<br />
be noted that the Cross Mill spaces are shorter and arguably less<br />
elegant and therefore some subdivision could be more tolerable.<br />
The building has an original ‘fireproof’ stair at its north and south<br />
ends, and links to the Malt Kiln to the north. The building also has<br />
a distinctive painted hoarding to its west elevation and gable end.<br />
Feilden Clegg Bradley Architects LLP
3.5 The Warehouse<br />
Built: 1805<br />
Listing:Grade 1<br />
Total Area: 1210m2<br />
No. of storeys: 4 plus roof void<br />
Average storey ht. 2.7m<br />
The Flax Warehouse was built in 1805 for the storage of <strong>flax</strong>. The<br />
building is Grade 1 listed, and is the 3rd oldest iron framed building<br />
in the world. During its subsequent conversion for use as part of<br />
the Maltings operation, it is believed to have been used for the<br />
storage of dye stuffs and grain.<br />
Internally, the original cast iron structure has been supplemented<br />
by a range of later timber props, tie rods and plates, which have<br />
not been examined in detail as part of the Masterplan study. It<br />
is assumed, however, that similar structural repairs and loading<br />
restrictions of 2.5kN/m2 would govern re-uses within the building<br />
following repair. (See ABA report).<br />
The building has strong physical lines with the Malt Kiln on ground<br />
to third floors. It also has an important relationship with the<br />
apprentice house which is located to the north. The building has<br />
few windows, which will be an important consideration in proposals<br />
for a change of use,and could have a significant impact on the<br />
existing appearance. The building has a hoist located on its north<br />
elevation.<br />
May 2004 Feilden Clegg Bradley Architects LLP
3.6 The Malt Kiln<br />
Built: 1898<br />
Listing: Grade 1<br />
Total Area: 650m2<br />
No. of storage: 2<br />
The Malt Kiln was built in 1998 as a key element of the new<br />
Malting business which commenced on the site in 1896. It is a<br />
Grade 1 listed building and has a key relationship with the adjacent<br />
Main Mill, Cross Mill and Warehouse, which it adjoins.<br />
The Kiln has a very distinctive pyramidal roof, capped by a<br />
ventilation ‘turret’, which historical photos show has been altered<br />
(for the worse) in recent years. This feature should be carefully<br />
considered and possibly restored, as part of proposals for re-use.<br />
The Malt Kiln has been prone to considerable decay following the<br />
theft of slates to its main roof slopes. This has left the building<br />
open to the elements for a number of years and subsequently it is<br />
believed that the internal perforated metal ‘drying floors’ are now<br />
beyond repair.<br />
The Malt Kiln is an important and significant volume at the core<br />
of the main group of historic buildings. It has previously been<br />
considered for public re-use as a theatre space for the Visual Arts<br />
Trust. The building also offers useful potential to achieve vertical<br />
circulation within and this should be explored further. The building<br />
is, however, closely located to the adjacent stairs within the Cross<br />
Mill and Main Mill.<br />
May 2004 Feilden Clegg Bradley Architects LLP
3.7 The Dye and Stove House<br />
Built: 1804/1850<br />
Listing: Grade 11*<br />
Total Area: 1450m2<br />
No. of storeys: 1 + Mezzanine<br />
The Dye and Stove House was originally built in 1803, and was<br />
subsequently largely re-built in 1852. The building consists of a<br />
large open space (with a later mezzanine floor) under an elegant<br />
and lightweight trussed roof. The roof extends the tradition of<br />
fine ironwork detailing on the site, and is supplemented by fine<br />
brickwork to the main elevations.<br />
Following the conversion of the building for use as part of the<br />
Maltings business, a number of hoists were added to assist the<br />
movement of material in and out of the building, together with<br />
dormer ‘lucams’ to enable loading and unloading from the adjacent<br />
railway sidings. These features represent an important change in<br />
the function of the building and should probably be retained as part<br />
of a scheme for future re-use.<br />
Internally the building has suffered from weather ingress and some<br />
corrosion to the structure.<br />
The flexibility of the building suggests that it would be suitable for<br />
a wide range of potential re-uses, including retail, restaurant and<br />
entertainment, office, and leisure or exhibition space.<br />
May 2004 Feilden Clegg Bradley Architects LLP
3.8 The Apprentice House<br />
Built: 1812<br />
Lisings:Grade 11*<br />
Total Area: 1450m2<br />
No. of storeys: 3 + basement<br />
The Apprentice House was built in 1812 to house workers of<br />
the Flax Mill, and is Grade II* listed. The building comprises two<br />
separate ‘houses’ of accommodation within its block and has a<br />
cellular form with simple domestic layouts to each floor around<br />
a timber staircase. The houses were used as Superintendents’<br />
housing from 1890.<br />
The building is located at the north end of the group and currently<br />
forms part of a courtyard, along with the Warehouse and adjacent<br />
concrete silo to the south.<br />
The buildings have suffered extensive damage due to neglect,<br />
vandalism and theft, and many of the internal fittings and fixtures,<br />
such as fireplaces, have been lost.<br />
The building would appropriately lend itself to a conversion for use<br />
as either offices or residential accommodation.<br />

3.9 The Stables and the Office<br />
Built: 1804<br />
Lisings: Grade II<br />
Total Area: 200m2<br />
No. of storeys: 2<br />
The Stables and office were built in 1804 and are listed Grade<br />
II. Their historical function was use as a stable and hayloft and a<br />
workshop and store. The buildings are located at the southern<br />
end of the site and form part of the boundary wall of the site.<br />
The buildings are domestic in scale and would suit a range of small<br />
scale uses, including residential, office, workshop or retail.<br />

3.10 The Silos<br />
The Silos, date from 1950 and 1960, and were introduced to<br />
improve the efficiency and capacity of the Matlings. Both Silos were<br />
built adjacent to the railway siding to receive incoming grain (South<br />
Silo) but also to enable storage of the outgoing goods (North Silo).<br />
Both silos have been damaged by vandalism and arson.<br />
The structural condition of the silos has not been assessed as a<br />
part of the Masterplan Study, however it is apparent that some<br />
reinforcement to the concrete structure is exposed and corroding.<br />
This may indicate more serious problems with the concrete which<br />
should be explored.<br />
Whilst the retention of the silos as part of a scheme for re-use of<br />
the site could be argued on the grounds that they are a part of the<br />
history of the site, it is considered that the grounds for demolition<br />
are likely to outweigh these issues. In addition to being potentially<br />
expensive to repair and difficult to re-use, both are considered<br />
to have a detrimental effect on the rest of the complex overall.<br />
They also restrict circulation and access potential to neighbouring<br />
buildings.<br />
It is proposed that they are demolished, however their footprint<br />
should be explored as potential developable space, if appropriate.<br />

A Lean-to Building containing the following:<br />
- Waste Room<br />
- Gas Meter<br />
- Thread Room<br />
The Drying Shed<br />
Wood Shed<br />
Gas House Complex<br />
It is anticipated that there are likely to be some archaeological<br />
remains associated with some of these buildings on the site, and<br />
the approach to any new development here must be careful to<br />
respect this.<br />
The North Site Area presents significant opportunities for a degree<br />
of enabling development on the site.<br />
The scale of development must sensitively address both the<br />
existing historic buildings and the scale of the Wingfield Close<br />
housing to the north.<br />

A Structural Appraisal report has been undertaken by Alan<br />
Baxter & Associates. This overview deals with the main mill,<br />
<strong>flax</strong> warehouse and cross mill, which form three of the ten<br />
buildings at Ditherington Flax Mill. The report sets down the<br />
following key points:<br />
The <strong>flax</strong> mill was initially developed between 1796 and 1812.<br />
The main mill, <strong>flax</strong> warehouse and cross mill were built during<br />
this period and are particularly important historically, as they<br />
represent, respectively, the oldest, third oldest and eighth<br />
oldest iron framed buildings in the world. The <strong>flax</strong> mill stopped<br />
operating in 1886 but was redeveloped as a maltings, which<br />
it operated as until 1986. Since then the buildings have<br />
remained empty and have suffered from a lack of maintenance<br />
and some vandalism.<br />
These buildings, in cultural terms, quite rightly deserve their<br />
Grade I listed status. Charles Bage’s design for the main mill<br />
was highly innovative. The engineering approach required<br />
for the redevelopment of this and the other buildings will be<br />
very challenging, requiring a higher level of engineering input<br />
compared to later cotton mills and warehouses. Central to<br />
this challenge will be to develop imaginative and intelligent<br />
solutions that are appropriate for these important buildings.<br />
Ideas which have been illustrated in this report need to be<br />
explored and tested in greater detail at the next stage.<br />
Charles Bage’s cast iron structure in the main mill appears<br />
to be of good quality construction and although historic<br />
records suggest Bage developed theories about how to<br />
design beams and columns, and carried out load tests, he<br />
failed to understand about hogging moments generated in the<br />
continuous beams.<br />
3.12 Structural Issues<br />
The resulting structure of the main mill, whilst well built,<br />
therefore has potential problems with cracking in these<br />
beams where hogging occurs. The structure is also relatively<br />
slender compared to many later 19th century cotton mills and<br />
warehouses in that it cannot support substantial imposed<br />
loads.<br />
A concept has been explored as part of this overview for<br />
tackling the deficiency in the beams by introducing reinforced<br />
concrete beams within the fill above the line of the existing<br />
beams. This will help improve the overall factor of safety in the<br />
beams to support an imposed floor load of 2.5kN/m². This<br />
approach would also address the beams that have cracked<br />
as the fractured sections can be simply hung from the new<br />
reinforced concrete structure to prevent the beams falling off<br />
their bearings.<br />
The columns within the main mill are generally slender and<br />
have limited fixity at their ends. This limits the load bearing<br />
capacity of the columns to an imposed load possibly less<br />
than 2.5kN/m² at present. The capacity of the columns can<br />
be increased however with the concept of running reinforced<br />
concrete beams above the existing beams. These new beams<br />
will be cast around each column base, introducing additional<br />
fixity, and will reduce the unrestrained length of the column.<br />
The initial appraisal of this approach allows an imposed load of<br />
2.5kN/m² to be justified.<br />
The floor loading capacity within the main mill therefore seems<br />
to be limited to about 2.5kN/m². This loading would be<br />
compatible with domestic, office and studio use, but not public<br />
use such as museums, shops, restaurants or bars.<br />
Feilden Clegg Bradley Architects LLP
May 2004<br />
3.12 Structural Issues<br />
Although very limited information relating to the structures<br />
of the cross-mill and <strong>flax</strong> warehouse is available, a similar<br />
engineering strategy appears appropriate in justifying the floors<br />
for an imposed loading of 2.5kN/m².<br />
This outline strategy for all three buildings needs to be<br />
confirmed through further detailed investigations and<br />
testing of the cast iron structure. This will give a far greater<br />
understanding of the details and quality of the existing<br />
structure. Given Bage’s innovative design and the slenderness<br />
of the structures, the structural appraisal will be highly<br />
challenging to deliver solutions that are appropriate for these<br />
very important structures. It is unlikely that imposed loads<br />
much in excess of 2.5kN/m² will be justified.<br />
Interpretation of the Building Regulations shows that the main<br />
mill, which is five storeys in height, does not need to comply<br />
with the rules relating to disproportionate collapse provided<br />
it is not used as public space. However, the approach to<br />
be adopted should be one where the robustness of the<br />
structure is not undermined by any structural alterations. The<br />
introduction of reinforced concrete beams will also improve the<br />
overall robustness.<br />
The cross-mill and <strong>flax</strong> warehouse are both four storeys<br />
in height and so do not need to comply, regardless of the<br />
proposed uses. However, a similar approach to robustness<br />
should be adopted.<br />
The original window openings in the main mill can be reopened<br />
again in principle from a structural point of view.<br />
These alterations will be disruptive and will require careful<br />
sequencing with repairs that are needed to delaminated areas<br />
of brickwork in order to maintain the structural integrity of the<br />
walls.<br />

May 2004<br />
4.1 Interested Parties<br />
The prominence of the site, the scale of public funding likely to be<br />
required as part of the solution, and the historical importance of the<br />
buildings combine to produce a long list of interested parties with a<br />
potential stake in the future of the site.<br />
The current list of Interested Parties and Stakeholders includes the<br />
following:<br />
Maltings Developments Ltd (site owners)<br />
Advantage West Midlands<br />
Adjacent Landowners<br />
Community organisations in Shrewsbury<br />
English Heritage<br />
Heritage Lottery Fund<br />
Local Residents<br />
National Amenity Bodies<br />
Shrewsbury & Atcham BC<br />
<strong>Shropshire</strong> County <strong>Council</strong><br />
It is likely that other organisations, including potential developers<br />
will emerge during the development of proposals. It should be<br />
noted that several potential developers have expressed an interest<br />
in the project during the course of the study to date.<br />
Feilden Clegg Bradley Architects LLP
4.2 Market & Property Context<br />
The Market and Property Analysis Report, undertaken by<br />
Towler Shaw Roberts, concludes the following points:<br />
There would be merit in exploring a mixed use development<br />
with a strong emphasis on provision of residential<br />
accommodation (new and conversion).<br />
There is scope to provide a mix of retail, food and<br />
drink facilities at ground floor level together with office<br />
accommodation to supplement the residential element.<br />
If a leisure use is likely to be viable, this would need to be<br />
complementary to the other users on the site.<br />
There may be some potential for provision of a community<br />
facility such as a doctors/dentist/health centre premises.<br />
Parts of the existing premises have potential for conversion<br />
to provide specialist managed workshop accommodation to<br />
satisfy specific requirements.<br />
It is doubtful that a single end user could be attracted to<br />
occupy the whole property.<br />
Access and car parking facilities need to be improved to<br />
ensure maximum commercial potential can be achieved.<br />
It would be very beneficial to include properties fronting Spring<br />
Gardens, which would enhance the The Flax Mill buildings.<br />
As part of the Stage II study consideration should be given<br />
to identifying potential users and occupiers for the various<br />
buildings for the whole project.<br />

The Grant Assistance Opportunities Report, undertaken by<br />
Dearle and Henderson, concludes the following points:<br />
Potential opportunities for Development Funding include:<br />
Advantage West Midlands / English Partnerships<br />
English Heritage<br />
Heritage Lottery Fund<br />
Local / Corporate sponsorship<br />
Private Developers<br />
Shrewsbury & Atcham Borough <strong>Council</strong><br />
<strong>Shropshire</strong> County <strong>Council</strong><br />
Other Grant Awarding Bodies<br />
4.3 Grant Assistance Opportunities<br />
4.4.2 The Key Conclusions are:<br />
No funding/grant opportunity should be dismissed at this early<br />
stage.<br />
The funding mosaic should be broad, thereby not relying upon<br />
one particular funding stream.<br />
Design proposals should not target one particular funding<br />
body’s priorities.<br />
Any regeneration scheme should first address the problems<br />
and the opportunities, then review the best suited potential<br />
funding.<br />
The size of grants potentially required necessitates an<br />
approach to the larger funding bodies, namely English<br />
Heritage, the Regional Development Agency and the Lottery<br />
<strong>Council</strong>.<br />
Very small grants may be obtained for specific works from<br />
Trusts, Foundations, corporate sponsorship or individuals.<br />
European Union Objective 2 and 3 funding is not currently<br />
applicable to this site.<br />

4.4 Local Interest - A Community View<br />
The Masterplan Study Work has been undertaken in the knowledge<br />
of the views of the Ditherington Community which were expressed<br />
during the ‘Listening into Action’ study during 2001-2002<br />
undertaken by RE:generate.<br />
During the consultation (which did NOT focus specifically on the<br />
Flax Mill site), the most needed improvements stated by local<br />
people were:<br />
Safe play areas for children<br />
More for children<br />
A Youth Club<br />
Traffic calming<br />
Tidier streets<br />
A better Community Centre<br />
It is hoped that public feedback following the presentation of the<br />
Masterplan Study approach in Ditherington on 18th May will assist<br />
in establishing an appropriate means for community views to be<br />
incorporated as the Scheme develops.<br />

5.0 Alternative Solutions/Visions<br />
May 2004 Feilden Clegg Bradley Architects LLP
May 2004<br />
5.1.1 Design Brief<br />
The brief for the project describes a future for the site which has<br />
the following characteristics:<br />
A vibrant and accessible mix of active uses<br />
A site which attracts both public and private investment<br />
An enhanced understanding of the site and its significance<br />
A beacon for high quality regeneration<br />
A secure and attractive place<br />
The highest standards of architectural design for new work<br />
A wide range of options for the redevelopment of the Ditherington<br />
Flax Mill site have been tested in order to meet these objectives.<br />
Whilst it is possible to achieve the stated brief requirements for the<br />
site through a variety of mixes of use on the site, this is achieved<br />
at varying levels of financial expense and impact to the historical<br />
integrity of the site.<br />
In order to be a deliverable scheme for the Flax Mill site, it will<br />
be important for the proposals to be acceptable in terms of<br />
Conservation Merit and Economic Viability.<br />
5.1.2 Conservation Merit<br />
The proposed scheme for the Flax mill site is likely to be required<br />
to achieve a broad level of support from potential funding<br />
stakeholders, and an acceptable level of public benefit must be<br />
achieved where public funding is incorporated.<br />
In conservation terms, development will be required to protect and<br />
enhance the historic significance of the site. This places some<br />
important constraints on devleopment potential.<br />
5.1 Assessment Criteria<br />
It is anticipated that permissible development will be:<br />
In line with stated conservation objectives for the site<br />
Respectful of the scale of the existing buildings<br />
Not unduly damaging to the historical significance<br />
Providing improved access (both physical and intellectual) to<br />
the site<br />
An improvement to the context and setting of the buildings<br />
5.1.3 Economic Viability<br />
The economic viability of the options for the site need to be tested<br />
on a range of levels, including the following:<br />
The acceptability of the proposed uses to the market<br />
The potential to meet the conservation deficit through<br />
engagement of potential funding partners<br />
The commercial confidence in the deliverability of the scheme<br />
A robust business plan for the future<br />

5.2 ‘Site by Site’ Options<br />
5.2.1 Considering the Study Area<br />
In order to provide a comparative assessment of the ‘conservation<br />
cost’ and ‘development potential’ of each part of the site, the<br />
Masterplan Study area was sub-divided into 6 key areas for<br />
assessment, as follows:<br />
1. The North Site Area<br />
2. The Historic Core Buildings<br />
3. Spring Gardens<br />
4. Haughmond Square<br />
5. Bus Depot<br />
6. Railway Triangle<br />
For the sake of simplicity, it will be noted that these site<br />
designations do not follow the exact lines of current ownerships.<br />
The site designations were used throughout the option appraisal<br />
phase and are referred to in the report of project costs prepared by<br />
Dearle and Henderson (see seperate report).<br />
The basic characteristics of each site are described in the following<br />
pages.<br />
Feilden Clegg Bradley Architects LLP
May 2004<br />
Site 1 - The North Site Area<br />
This site includes the Apprentice House and the areas to the North<br />
and the East. We believe that there is a strong justification for some<br />
development on this site to assist with the development costs of<br />
the Historic Core Buildings. The site sits to the north of the main<br />
buildings and currently vehicular access is severely restricted as<br />
access is only possible through the main buildings.<br />
There is the potential to provide independent access from the<br />
rear of the site. However, this would result in the introduction of a<br />
ramp either through or over the listed ‘curtilage wall’, eroding the<br />
prominent boundary of the site.<br />
It is believed that a better access could be formed from the east (ie<br />
through the Bus Depot site) however this would clearly be subject<br />
to further negotiation.<br />
The following key factors determine the development of the<br />
North Site area:<br />
The relationship with the Historic Core Buildings.<br />
The integration of the Apprentice House.<br />
The provision of a new access road.<br />
The quantity of car-parking required for any new development.<br />
The proximity to, and over looking of, the Wingfield Estate to<br />
the North.<br />
5.3 The Core Area : Sites 1 and 2<br />
Site 2 - The Historic Core Buildings<br />
This area contains the majority of the Historic Buildings. The physical<br />
constraints and the structural condition of the historic buildings incur<br />
high repair and upgrade costs. There is very limited scope for any<br />
enabling development in close proximity to the buildings (site 2). The<br />
buildings themselves could be developed to provide a limited mix of<br />
uses, including workspaces, retail, interpretation and residential with<br />
any development appropriate to the historic fabric. These options are<br />
further considered in section 5.6 of this report.<br />
The following key factors determine the re-use of the Historic<br />
Buildings:<br />
The Reopening of the Mill Windows<br />
The Demolition of the Silos<br />
Consideration of the level of sub-division of each floor<br />
Disabled Access and Escape Strategies<br />
Circulation Patterns<br />
Servicing of new uses<br />
Structural floor loadings<br />
Feilden Clegg Bradley Architects LLP
May 2004<br />
Site 3 - Spring Gardens<br />
To the east, the Historic Buildings overlook a range of modern<br />
small scale businesses which separate them from Spring Gardens<br />
road. These businesses partly occupy the former site of the<br />
<strong>Shropshire</strong> Union Canal, which ran along the eastern boundary<br />
of the Mill site until its closure in 1944. There is the potential,<br />
in redevelopment, to open up views to and from the Historic<br />
Core Buildings and to improve their setting and visibility. This is<br />
considered an important factor to achieve the brief requirements.<br />
There is also the potential to provide a new public space for<br />
interpretation and to redevelop in a manner that refers to or<br />
respects the line of the canal.<br />
Developing the Spring Gardens Site offers an opportunity to<br />
address the following key issues:<br />
The street frontage and setting of the Flax Mill<br />
The visual accessibility of the site<br />
The relationship to the Town<br />
The interpretation of the former canal<br />
Site 4 - Haughmond Square<br />
This site lies to the east of the Historic Buildings and has been<br />
identified as separate to the Spring Gardens site because of two<br />
Victorian brick houses which are part of the former Haughmond<br />
Square. The buildings currently occupying the road side site were<br />
built as part of the Mill buildings complex.<br />
Any development on this site will need to consider the<br />
following:<br />
5.4 Other Sites : Sites 3, 4, 5 and 6<br />
Appropriate uses for the Haughmond Square houses<br />
The issues of gaining road side access to any development<br />
The former position of the <strong>Shropshire</strong> Union Canal<br />
The potential to acieve a pedestrian entrance to site 2<br />
Site 5 - Bus Depot Site<br />
The bus depot is situated to the North East of the Historic<br />
Buildings, on Spring Gardens. The bus depot introduces a<br />
particular level of additional traffic movements on Spring Gardens,<br />
and bus maintenance activities. It is acknowledged by Arriva that<br />
the existing depot facilities are not ideal, however they are well<br />
located in operational terms.<br />
Developing the Bus Depot Site offers an opportunity to<br />
address the following issues:<br />
Potential site for creating new access road<br />
Resolution of the Highways issues regarding the provision of a<br />
potential new site entrance<br />
Potential to compliment development to the North Site Area<br />
Potential to make reference to the line of the <strong>Shropshire</strong> Union<br />
Canal<br />
Site 6 - Railway Triangle<br />
This site contains a pumping station and is hemmed in by the<br />
railway line embankment and site retaining wall. In view of the<br />
perceived difficulty of providing an acceptable building here, it is<br />
proposed this area is used for a less intensive use, such as car<br />
parking (in association with site 2 uses).<br />

May 2004<br />
5.5 Whole Site Options<br />
The exploration of development opportunities and constraints on a<br />
‘site by site’ basis (and the associated costs) has been tested in a<br />
series of ‘whole site options’ in order to establish the approximate<br />
level of ‘conservation deficit’ within a range of potential redevlopment<br />
scenarios.<br />
The 5 options presented in this section are as follows:<br />
Minimum Scheme<br />
Heritage Destination<br />
Community Focus<br />
Residential Community<br />
Intensive Re-use<br />
A broad range of assumptions have been made as part of the<br />
sketch design exercise. The basic premise, however, has been<br />
to test the effect of an increasing intensity of redevelopment, both<br />
within the buildings and on adjacent sites.<br />
Each of these schemes has been discussed and assessed in terms<br />
of its Conservation Merit and Economic Viability during design<br />
progress meetings.<br />
Feilden Clegg Bradley Architects LLP
May 2004<br />
5.5.1 Whole Site Option 1 : Do Minimum<br />
5.5.1 The Do Minimum Scheme<br />
This is a ‘light touch’ option that rates highly in terms of<br />
conservation merit. The level of subdivision is kept to the absolute<br />
minimum and the modification and upgrading works are also<br />
minimised. However, in all potential uses (apart from leave empty or<br />
not changing the use) means of access and escape would need to<br />
be improved.<br />
Potential uses include:<br />
Leave empty<br />
No change of use (i.e. Storage)<br />
Interpretation<br />
Specialist Retail<br />
Antiques<br />
Garden Centre<br />
Advantages:<br />
Lower Impact<br />
Less complexity<br />
Disadvantages:<br />
Spring Gardens unresolved<br />
Lower income potential<br />
Less community facility<br />
Conclusions<br />
This option minimises the level of expenditure however, it probably<br />
does not achieve a longer term sustainable solution for the site.<br />
Feilden Clegg Bradley Architects LLP
May 2004<br />
5.5.2 Whole Site Option 2 : Heritage Destination<br />
5.5.2 A Heritage Destination<br />
This option also rates highly in terms of conservation merit. The<br />
level of subdivision is kept to the minimum. However, modification<br />
and upgrading of site infrastructure works would need to be<br />
introduced. The North Site area is considered for development<br />
to residential to assist with the costs of the works to the Historic<br />
Buildings.<br />
Potential Uses include:<br />
Interpretation<br />
Specialist Retail<br />
Antiques<br />
Garden Centre<br />
Residential<br />
Advantages:<br />
Lower Impact<br />
Less complexity<br />
Priority to Heritage use<br />
Disadvantages:<br />
Spring Gardens unresolved<br />
Lower income potential<br />
Less community facility<br />
Conclusions:<br />
The format of the existing historic buildings is suitable for<br />
undivided, single volume, interpretation spaces or specialist retail<br />
use. The variety of spaces offered by the buildings (Main Mill,<br />
Dye House and even Silos) would lend themselves to such a use,<br />
however, there are important potential restrictions on floor loadings.<br />
The Mill as a Heritage destination could attract public funds and<br />
may be assisted by the development of other site areas adjacent.<br />
The long term business case for such a low intensity use would<br />
require careful evaluation as part of funding applications.<br />
Feilden Clegg Bradley Architects LLP
May 2004<br />
5.5.3 Whole Site Option 3 : Community Focus<br />
5.5.3 A Community Focus<br />
This scheme shows a slightly more intense level of development.<br />
Although the level of internal subdivision of historic buildings is low,<br />
there are extensive modification and upgrading infrastructure works<br />
necessary to provide the proposed uses. The North Site area is<br />
considered for development to residential to assist in costs. The<br />
Spring Gardens sites are developed for community use; the road<br />
side site is cleared to become a public area, and the canal is reinstated’<br />
in the form of a water feature. There is a Health Centre on<br />
the Haughmond square site and the Malting Kiln is converted to<br />
provide a Hall for Community Use.<br />
Potential Uses include:<br />
Retail<br />
Leisure<br />
Restaurant<br />
Community Use<br />
Office Use<br />
Residential<br />
Advantages:<br />
Wide mix of uses<br />
Wide range of users<br />
Disadvantages:<br />
Intensive subdivisions<br />
Heritage compromise<br />
Barrier to Spring Gardens<br />
Conclusions:<br />
As the extent of the considered site has been increased to provide<br />
community facilities, this scheme is more reliant on public funds.<br />
The development of the rest of the site has been increased to<br />
assist, but it is anticipated that the returns would not be sufficient<br />
to cover costs. This scheme involves the purchase of adjacent<br />
sites for the improved setting and benefit of the historic buildings.<br />
Feilden Clegg Bradley Architects LLP
May 2004<br />
5.5.4 Whole Site Option 4 : Residential Community<br />
5.5.4 Residential Community<br />
This option considers creation of a new ‘community’ on the site<br />
through residential converstions and new houses. The uses<br />
proposed necessitate a higher level of subdivision and require<br />
extensive modification and upgrading infrastructure works.<br />
The North Site area becomes residential development to assist<br />
will the costs of the Mill Buildings. The Spring Gardens sites are<br />
allocated for community use; the road side and the Haughmond<br />
Square site becoming a public ‘Green’ and the canal is ‘reinstated’<br />
as a water feature. The Malting Kiln is converted to<br />
provide a Hall for Community Use.<br />
Potential uses include:<br />
New ‘Ditherington’ Green<br />
Residential (houses and apartments)<br />
Interpretation / Community (Kiln)<br />
Restaurant / Bar<br />
Gym / Leisure<br />
Advantages:<br />
High value re-uses<br />
Community facility<br />
Disadvantages:<br />
Intensive sub-divisions<br />
Heritage compromise<br />
Low employment use<br />
Conclusions<br />
This scheme is considered to require unacceptable levels of<br />
subdivision to create private apartments. The ground floors of all<br />
buildings are made available for public use in the form of either<br />
retail or leisure to compensate. An intention with this scheme is<br />
that the Spring Gardens sites are cleared to allow visual access to<br />
the Historic Core Buildings. However, the costs of developing these<br />
sites increases public funding needed.<br />
Feilden Clegg Bradley Architects LLP
May 2004<br />
5.5.5 Whole Site Option 5 : Intensive Re-use<br />
5.5.5 Intensive Re-use<br />
This scheme illustrates the most intensive level of development.<br />
It includes all sites, extensively developing each one. The hotel<br />
use necessitates an extremely high level of subdivision and<br />
requires internal and external modifications. The North Site<br />
area along with the Bus Depot site is considered for additional<br />
residential development. The Spring Gardens sites are allocated for<br />
community use and retail; the road side becoming retail and the<br />
Haughmond Square site becoming a Health Centre for community<br />
use. A linear park is introduced in front of the Mill Buildings and the<br />
canal is ‘re-instated’ as a water feature.<br />
Potential Uses include:<br />
Hotel<br />
Restaurant / Bar<br />
Gym / Leisure<br />
Townhouses<br />
Apartments<br />
Health Centre<br />
Retail<br />
Advantages:<br />
High value re-uses<br />
Wide mix of uses<br />
Wide range of users<br />
Disadvantages:<br />
Intensive sub-divisions<br />
Heritage compromise<br />
Over intensive land uses<br />
Barrier to Spring Gardens<br />
Conclusions:<br />
This scheme uses unacceptable levels of subdivision to create<br />
a commercially viable Hotel. It is also believed that to convert<br />
the Historic Core Buildings incurs such costs (economically and<br />
conservation) that finding an acceptable solution is unlikely.<br />

5.6 Core Buildings : Options<br />
In a similar manner to the testing ot the individual sites, the impact<br />
of sub-dividing and re-developing the historic mill buildings has<br />
been tested for a range of potential re-uses.<br />
The issue of subdivision<br />
The level of subdivision ishown follows the level of intensity of reuse<br />
proposed within whole site options 1 to 5. Whilst it will be<br />
noted that in all options it is proposed that the lower floors are<br />
used for publicly accessible functions (e.g. retail, bar or restaurant)<br />
the impact on the key spaces at upper floor levels is more<br />
profound.<br />
It will be noted that as the level of subdivision increases, the spaces<br />
become more and more domestic in scale, the levels of intervention<br />
increase proportionately and the conservation merit falls as a result<br />
of more and more of the structure becoming hidden.<br />
Feilden Clegg Bradley Architects LLP
May 2004<br />
5.6 Core Buildings : Options<br />
The principle of subdivision of the core buildings was also tested<br />
in plan arrangements to explore the level of subdivision and<br />
supporting infrastructure likely to be required for each type of use.<br />
The options range from a reliance on the existing services and<br />
infrastructure within option 1 (no change) to an intensive upgrade<br />
for re-use as an Hotel (option 5).<br />
Options 3 and 4 consider the ‘balanced’ options of introducing<br />
some subdivision of the key spaces to assist amenity and fire<br />
escape, and introduce new circulation cores which are external<br />
to the building. These options suggest light office use and large<br />
apartment use respectively.<br />

As Existing Key Ingredients<br />
May 2004<br />
6.1 Masterplan Vision : Key Ingredients<br />
The approach to creating a Masterplan Vision for the site has been<br />
informed by a range of key factors, which are summarised below,<br />
and described in the diagramme adjacent.<br />
1. The integrity of the Core Group of buildings must be respected<br />
and enhanced.<br />
2. Opportunities for new development should seek to enhance the<br />
historic site and setting.<br />
3. The line of the former canal and its relationship with the<br />
buildings should be a part of plans for the future.<br />
4. A new community facility, such as a Health Centre could be<br />
created along Spring Gardens, perhaps on the Haughmond<br />
Square site.<br />
5. A new public garden could be created in front of the buildings<br />
as a key feature of the new setting.<br />

6.2 ‘Best Fit’ Scheme<br />
Assessment of the broad range of options, together with the<br />
conclusions drawn from the conservation plan and site by site<br />
studies has led to preparation of a ‘Best Fit’ scheme, which<br />
it is believed presents an optimum balance of the range of<br />
opportunities and constraints affecting the site.<br />
The Masterplan Vision can be summarised as a number of interrelated<br />
‘zones’ of development in the following three categories:<br />
Zone 1. The Historic Core Buildings<br />
Zone 2. New Development<br />
Zone 3. New Setting<br />
Each of the ‘zones’ contains a number of options for development<br />
which may affect the intensity, value and cost of development<br />
indicated. Further work is required to explore these options in<br />
more detail during the next stage of the study. The basic range of<br />
issues concerning the level of development indicated for each zone<br />
is described on the following pages.<br />

6.3 ‘Best Fit’ Scheme - Zone 1<br />
The approach to Zone 1 puts the concerns for the historic core<br />
of buildings at the centre of the proposals for redevelopment. Its<br />
main features are as follows:<br />
The repair and redevelopment of the buildings should be<br />
undertaken in accordance within the recommendations set<br />
down within the Conservation Plan for the site.<br />
The mix of proposed uses should ideally fit the building (rather<br />
than extensive alterations to the building being necessary to<br />
accommodate a particular re-use).<br />
An appropriate re-use would be a mix of retail, leisure, and<br />
museum space at low levels, combined with ‘loose fit’<br />
residential and work spaces to upper floors.<br />
Public funding for the works is likely to be required as none of<br />
the options explored are commercially viable.<br />
It is considered that the scheme for the re-use of the buildings<br />
could be beneficially undertaken by a ‘Not for Profit’ Trust,<br />
such as a Building Preservation Trust. Such an organisation<br />
may have access to particular sources of public funding and<br />
have the ability to seek lower profit margins in re-development.<br />

6.4 ‘Best Fit’ Scheme : Zone 2<br />
The Zone 2 area covers the main sites where beneficial new<br />
development could be achieved. The key characteristics of the<br />
Zone 2 proposals are as follows:<br />
A mix of new housing is indicated which includes town house,<br />
new apartments and a residential converstion of the Apprentice<br />
House.<br />
The redevlopment of the Bus Depot site introduces a new use<br />
on the site as part of the development. The densities shown<br />
are low, and the siting of new housing respects the former line<br />
of the canal and opens up view from Spring Gardens from the<br />
north.<br />
The layout creates the opportunity for a new road access to<br />
the site.<br />
The scale of new development indicated is considered unlikely<br />
to contribute a significant amount towards the development<br />
costs of Zone 1 as the densities shown, however they could<br />
offer significant wider benefits.<br />

6.5 ‘Best Fit’ Scheme : Zone 3<br />
The Zone 3 proposals create the main setting for the historic<br />
buildings, and maximise the exposure of the site to passing<br />
pedestrians and motorists on Spring Gardens. The key<br />
characteristics are as follows:<br />
A water feature to mark the former line of the canal is created<br />
as both an aid to interpretation and as part of a new setting for<br />
the buildings and public spaces.<br />
A new garden is created along Spring Gardens as a flexible<br />
and high quality public space. This space could provide<br />
interpretation for the buildings.<br />
The Haughmond Square area is proposed for a re-use as<br />
part of the new mix of community resources inspired by the<br />
project. The buildings could accommodate a Health Centre,<br />
for example.<br />
Feilden Clegg Bradley Architects LLP
The preparation of the Masterplan Strategy has confirmed that there<br />
are potentially some exciting opportunities for the future of the Flax<br />
Mill site, however these are also linked to some major challenges in<br />
delivering the vision.<br />
In particular it is clear that the delivery of the project will require the<br />
following inputs:<br />
A strong funding partnership<br />
A robust project implementation plan<br />
A committed champion for implementation of the Masterplan<br />
Vision<br />
A strong consultant team<br />
Broad public support<br />
There are also a range of key design stage inputs that are<br />
recommended as part of the delivery of each ‘zone’ of the Vision<br />
that has been indicated. These include the following:<br />
Zone 1 – The Historic Buildings<br />
The buildings should be made safe and secure immediately.<br />
A ‘guardian’ for the Zone 1 area is required.<br />
Further design work to establish cost and design constraints is<br />
needed.<br />
A sensitive scheme which will attract public funding needs to<br />
be developed.<br />
Zone 2 – New Development<br />
7.0 Next Steps<br />
Design codes and supplementary planning guidance should be<br />
developed.<br />
Development could be undertaken by the private sector.<br />
Development profits would contribute to the scheme for Zone<br />
1.<br />
Zone 3 – A Public Space<br />
Requires support from the <strong>Council</strong> and the public.<br />
Requires more detailed consideration (including the future of<br />
Haughmond Square).<br />
May 2004 Feilden Clegg Bradley Architects LLP
8.0 Conclusions<br />
The Ditherington Flax Mill is of oustanding importance. The<br />
historic buildings are of international significance, and they are of<br />
considerable regional interest as the largest remaining Maltings<br />
Complex in Shrewsbury.<br />
Following a period of sustained redundancy, however, the site is<br />
now in an extremely poor condition. The buildings are regularly<br />
vandalised and they have become gradually surrounded by a range<br />
of business uses which create a physical and psychological barrier<br />
to progressive change. It is recognised that the situation requires<br />
urgent action.<br />
The Masterplan Study has considered the broad range of<br />
opportunities and constraints affecting the buildings including<br />
their condition, structure, historic merit, flexibility and costs of reuse.<br />
The study has also considered the wider opportunities and<br />
constraints presented by the surrounding sites as part of A Vision<br />
for the Future.<br />
Clearly the best way of conserving the special significance of the<br />
Flax Mill site is to seek its return to an appropriate and sustainable<br />
use as soon as possible. The Study has demonstrated that, given<br />
the support of a range of funding stakeholders and key interested<br />
parties, it would be possible to deliver a vision of the site which<br />
could deliver all of the stated aspirations of English Heritage,<br />
Shrewsbury and Atcham Borough <strong>Council</strong> and Advantage West<br />
Midlands.<br />
The delivery of the Vision will require a capable and committed<br />
agency and significant public funding. It is firmly believed , however,<br />
that the site can offer a significant and enduring range of benefits<br />
for a broad range of residents, users and visitors to the site as part<br />
of a coherent Masterplan Vision.<br />

Introduction to the Study<br />
Since their closure in 1987, the historic buildings on the Ditherington Flax<br />
Mill site in the north of Shrewsbury have been in a state of gradual decline.<br />
Following a series of failed development attempts, English Heritage, acting<br />
in partnership with Shrewsbury & Atcham Borough <strong>Council</strong> and Advantage<br />
West Midlands appointed a team led by Feilden Clegg Bradley Architects<br />
in November 2003, to report on the range of problems affecting the site and<br />
to explore the possibilities of a ‘Masterplan Vision’ for the future.<br />
This leaflet presents a summary of the findings of the Study so far and<br />
invites your feedback on the key points and proposals which have arisen to<br />
date.<br />
The Study has been undertaken in 2 stages.<br />
The first stage, Information Gathering,<br />
consisted of:<br />
• Historical Research<br />
Site and Building Assessments<br />
Writing a Conservation Statement<br />
A Property Market Appraisal<br />
An Assessment of Funding Opportunities<br />
The second stage, Option Appraisal, looks<br />
at the options for the future of the whole site<br />
including:<br />
Design Options for site and Buildings<br />
A Cost review of Options<br />
A Feasibility Assessment<br />
Identification of next steps<br />
The Ditherington Flax Mill<br />
The Flax Mill site was first developed in 1796, and comprises a remarkable group<br />
of Grade 1 listed structures which including the oldest iron-framed building in<br />
the world. These structures are widely recognised as extremely elegant and<br />
innovative pieces of structural engineering, the earliest of which was built only<br />
18 years after the completion of the Iron Bridge at Coalbrookedale. Since the<br />
closure of the Maltings operation of the site in 1987, the Flax Mill site has been in<br />
private ownership. Following a number of failed attempts to re-develop the site<br />
it has gradually fallen into a state of disrepair, suffering the effects of vandalism<br />
and serious water ingress. The site since been included on English Heritage’s<br />
national ‘Buildings at Risk’ register since..... In December 2003, a programme<br />
of Urgent Works to restore the weather proof nature of the buildings was begun.<br />
These works were completed in March 2004.<br />
The Study assists in the understanding of the significance of the buildings,<br />
the problems surrounding their neglect and points to possibilities for<br />
redevelopment and re-use. As a consequence of the Study, there is now<br />
a clearer framework within which positive change may be structured. The<br />
Study has involved meetings and discussions with many individuals and<br />
organisations, some of whom have differing perspectives on the future of<br />
the Mill.<br />
Redevelopment Opportunities<br />
The Masterplan Vision arising from the Study seeks to provide:<br />
A mix of uses on the site, including retail, interpretation, employment<br />
and some residential development.<br />
Improved public access to the site and to the historic buildings.<br />
A new public garden, including an interpretation of the former canal.<br />
An attractive opportunity for public and private investment.<br />
Many physical constraints such as the structural condition of the historical<br />
buildings make a commercially viable redevelopment of the entire site difficult. It is<br />
envisaged that delivery of the Masterplan Vision would need to attract significant<br />
levels of public funding. The scheme for the re-use of the historic buildings will<br />
also need to be economically viable and sustainable. As part of the scheme it is<br />
hoped that these could be converted to accommodate a range of new uses. The<br />
Study identifies that there are associated repair and upgrading costs.<br />

The Masterplan Vision has been<br />
considered as a number of inter-related<br />
‘zones’ of development in the following<br />
three categories:<br />
1. The Historic Core Buildings<br />
A mix of potential uses includes<br />
workspaces, retail, museum and<br />
residential.<br />
Development appropriate to the<br />
historic fabric.<br />
Perhaps to be undertaken by a ‘not<br />
for profit’ Trust.<br />
High repair and upgrade costs.<br />
Potential assistance from the<br />
Heritage Lottery Fund<br />
2. New Development<br />
A new mix of housing for<br />
‘sustainable living’.<br />
High design quality.<br />
Providing safer site access for all<br />
areas of the study area.<br />
Respecting the line of the canal.<br />
Assists with the development<br />
costs of the Historic Core<br />
Buildings.<br />
3. New Setting<br />
Opens up views to and from the<br />
Historic Core Buildings.<br />
Provides a new public space.<br />
Potentially provides a site for<br />
interpretation.<br />
Requires public and <strong>Council</strong><br />
Support.
A Summary of the Study<br />
April 2004<br />
A report by Feilden Clegg Bradley Architects LLP<br />
The Ditherington Flax Mill Shrewsbury<br />
The 12 Key Issues<br />
1. The core buildings are of international significance. The<br />
Main Mill is the flagship and is the oldest iron framed<br />
building in the world. Restoration of the core buildings and<br />
the redevelopment of the whole site and adjacent areas<br />
must be to the highest standards.<br />
2. Whilst empty for 15 years, the repair costs have escalated<br />
and the site is in the highest category of EH’s Buildings<br />
At Risk register. Urgent action is required to safeguard the<br />
long term future of the historic buildings.<br />
3. The significance of the buildings is difficult to appreciate<br />
due to the adjacent land uses and the current lack of<br />
accessibility.<br />
4. The historic buildings are elegant and innovative<br />
pieces of structural engineering, however their unique<br />
design presents important limitations to the acceptable<br />
range of re-uses.<br />
5. The site would best suit a mix of uses which encourages<br />
a range of users, including residential, retail, leisure and<br />
perhaps a community facility.<br />
6. There is very limited scope for any enabling development<br />
near the historic buildings, and a road would need to be<br />
created to service this.<br />
7. The redevelopment of the site offers a significant<br />
opportunity to focus community interests and act a<br />
focus for wider regeneration of the Ditherington area.<br />
8. Improvement of the Spring Gardens site is an essential<br />
step to improving interpretation and amenity of the site.<br />
9. Any scheme for redevelopment will be expensive and<br />
a significant ‘Conservation Deficit’ exists within all<br />
potentially acceptable options. The input of public funding<br />
must deliver public benefit.<br />
10. There is an opportunity to interpret the line of the<br />
<strong>Shropshire</strong> Union canal and new build should not<br />
prejudice its future reinstatement.<br />
11. A number of potential developers have expressed an<br />
interest in the site. However, it must be noted that the re-<br />
use of the core buildings is likely to require a special<br />
approach.<br />
12. During the next stage of work it will be essential for the<br />
proposals to be developed by a committed professional<br />
team in partnership with a range of funding stakeholders.<br />
