Why it was refused
Reason
As stated on the decision notice
1
The proposed extensions by reason of their scale, bulk and massing would result in an insubordinate
addition to the host dwellinghouse that would fail to respond to the original architectural detailing and would be
contrary to the objectives of adopted Lambeth Design Guide and policies Q5 and Q11 of the Lambeth Local Plan
(2021).

2
The proposed extensions by reason of their siting and depth would result in an unacceptable impact on the
residential amenity of neighbouring occupiers especially in regard to an increased sense of enclosure contrary to
the objectives of policy Q2 of the Lambeth Local Plan (2021).
3
In the absence of a S106 agreement, the application fails to mitigate the impacts of the proposed
development, as such, the proposal is contrary to the objectives of policy D4 of the Lambeth Local Plan (2021).
