combined with the retail and leisure extension, it is considered that there is sufficient
distance to maintain privacy. It is therefore considered that there would be no
significant in terms of impact on the adjoining properties in this respect.
4.43 The overshadowing effects of the recently approved leisure and retail extension
was considered by way of a sun-path analysis which revealed minor impacts to the
proposed dwellings that could be built within the phase 2 development. The analysis
demonstrated that there would be no over-shadowing of properties to the east of the
West Cross Route. Officers note that the proposed office extension is lower in height
than the retail/leisure extension and is set well back from the north eastern corner of the
shopping centre. As such, the effect of the office extension would be less than that of
the retail/leisure extension. In light of the position on the building and its scale and
height, officers conclude that there would be no additional overshadowing of the
adjacent properties on Hunt Close or within the Edward Woods estate which are
adjacent to the shopping centre, or of the adjacent new dwellings within the phase 2
development.
4.44 As such, it is considered that the office extension on its own and when combined
with the retail/leisure extension would not result in a significant impact on the amenity of
surrounding residential occupiers, in terms of overshadowing, privacy, daylight and
sunlight. The proposal would be acceptable and in accordance with policies 3.5, 3.6,
3.8, 7.3, 7.6, 7.7, 7.14 and 7.15 of the London Plan (2011); policies BE1 of the London
Borough of Hammersmith and Fulham Core Strategy (2011); and policies DM G1 and
DM G3 and SPD Design Policy 8.
Noise
4.45 London Plan Policy 7.15 (Reducing Noise and Enhancing Soundscapes) considers
the implications of noise as part of development proposals, stating that development
proposals should seek to minimise the potential adverse impacts of noise on, from,
within, or in the vicinity of, development proposals.
4.46 Development Management Local Plan DM H9 states that noise generating
development will not be permitted, if it would be liable to materially increase the noise
experienced by the occupants/users of existing or proposed noise sensitive uses in the
vicinity. SPD Amenity Policies 18 and 24 are also applicable for assessing noise
generating development.
4.47 The proposals include the relocation of existing plant to a plant deck on the
existing roof to the south of the office extension.
4.48 Extensive acoustic data was collected for the original development of Westfield
London and this was used to determine an acceptable acoustic specification for those
works. As these circumstances have not changed, the applicant proposes to follow
these guidelines for the new extension so that the internal and external noise levels
remain within the same boundaries.
4.49 The main sources of noise at the eastern façade are road traffic on the West Cross
Route and trains on the West London line. Assuming that the noise levels measured for
the original Westfield development are consistent with the noise and vibration levels,
measured behind the new façade the proposals would be within appropriate standards.
