Why it was refused
Reason
As stated on the decision notice
1
The proposed roof extensions, by way of their excessive bulk and discordant
design would form an inappropriate and harmful addition to the host property, in
contravention of Wandsworth Local Plan (2023) policies LP1, LP5 and the
Housing SPD (2016)
2
The proposed roof terrace, by way of its excess size and inadequate surround
would negatively impact the amenity and privacy of neighbouring residents in
Director of Place: Paul Moore
contravention of Wandsworth Local Plan (2023) policy LP2.
In dealing with this application the Council has implemented the requirement in
the National Planning Policy Framework to work with the applicant in a positive
and proactive manner and the Council has, as far as practicable, sought
solutions to problems arising in relation to dealing with the planning application.
We have made available detailed advice in the form of our statutory policies in
the Local Plan consisting of the Core Strategy, Development Management
Policies Document, Supplementary Planning documents and where appropriate
the Site Specific Allocations Document as well as offering a full pre application
advice service, in order to ensure that the applicant has been given every
opportunity to submit an application which is likely to be considered favourably.
In addition further guidance was offered to the applicant by the case officer
during the processing of the application to identify amendments to address
those elements of the scheme considered unacceptable. However, the
necessary amendments to make the application acceptable are substantial and
would materially change the development proposal. They would require further
consultations to be undertaken prior to determination, which could not take
place within the statutory determination period specified by the Department of
Communities and Local Government. You are therefore encouraged to consider
submission of a fresh application incorporating the material amendments set out
below which are necessary to make the scheme acceptable.
Required amendments:
- Redesign roof extension
- Reduce size of roof terrace and implement 1.7m tall obscure glazed
balustrade
