each the guidelines and has an existing VSC level of 4.75% which is well
below the 27% recommended. In this instance the development would have a
minor adverse impact. This is considered to be acceptable by Right to Light
Consulting.
9.14 Market Towers
A total of 357 rooms were assessed as part of the development, 333 rooms
(93%) meet BRE Guidelines for VSC and NSL. The remaining 24 rooms which
are believed to accommodate living/ kitchen/ dining rooms, breach both VSC
and NSL criteria. The retained level of VSC range from 18.31% to 25.94%,
which is considered to be acceptable within an urban city location. This has
been assessed independently by Right to Light Consulting, who agree with this
assessment.
9.15 Overshadowing of Gardens and Open Space
The availability of sunlight should be checked for all open spaces where sunlight
is required. This would normally include:
• Gardens, usually the main back garden of a house
• Parks and playing fields
• Children’s playgrounds
• Outdoor swimming pools and paddling pools
• Sitting out areas, such as those between non-domestic buildings and in
public squares
9.16 The BRE guide recommends that at least 50% of the area of each amenity
space listed above should receive at least two hours of sunlight on 21st March.
If as a result of new development an existing garden or amenity area does not
meet the above, and the area which can receive two hours of sun on 21st March
is less than 0.8 times its former value, then the loss of light is likely to be
noticeable.
9.17 GIA have applied the BRE Overshadowing to Gardens and Open Spaces test to
the neighbouring gardens at 101 to 111 Wandsworth Road. The amenity areas
at the front of the properties surpass the minimum BRE recommendations. The
rear amenity areas fall slightly short of the recommendations although the
losses are small in absolute terms. The non-compliance with the BRE
recommendations is largely due to the fact the rear amenity areas are small and
therefore the boundary walls already limit sunlight availability at ground level.
9.18 GIA have also applied the overshadowing test to the proposed amenity areas
within the Vauxhall Square development itself. The results show that the
proposed development would provide a combination of well sunlit and shady
amenity areas. GIA have also prepared a transient overshadowing assessment
and officers confirm that this is representative of the levels of overshadowing
that would occur as a result of the proposed development.
