Why it was refused
Reason
As stated on the decision notice
1
The proposed conversion of the first floor rear layout into Bedrooms A, B, and C relies entirely upon
high-level, narrow flank windows which, by reason of their restricted vertical positioning, depth, and
orientation, fail to provide an acceptable horizontal outward view or sufficient natural light for
habitable rooms. The configuration creates an oppressive, enclosed, and low-quality living
environment that is detrimental to the health and well-being of future occupiers, contrary to Policy
D6 of the London Plan 2021 and Policy 9 of the Sutton Local Plan 2018.
2
The applicant has failed to provide sufficient information, by way of professional noise and odour
impact assessments, to demonstrate that future occupiers of the residential unit will be adequately
protected from noise, vibration, and odours from the ground floor commercial restaurant and its
associated rear extraction flue, as well as traffic noise from Stafford Road. In the absence of these
assessments and details of appropriate mitigation, the proposal represents an inappropriate form of
development that would result in harm to the standard of amenity for future tenants, contrary to
Policy 34 of the Sutton Local Plan 2018 and Policy 7.15 of the London Plan.
