Why it was refused
Reason
As stated on the decision notice
1
The applicant has failed to demonstrate through the submission of cogent information that the proposed
rear extension would not have an unacceptable adverse impact on the closest habitable room windows at
No. 160 Hamilton Avenue in terms of daylight/sunlight. Given the scale of the extension and the proximity of
neighbouring windows it is considered that there is a likelihood that the development would breach the
"BRE 45 Degree Rule" and reduce light entering into the neighbouring habitable room, which in turn would
harm the residential amenities of the occupants of the neighbouring property. The proposal is therefore
contrary to policy D3 of the London Plan 2021 and policy DM10 of the LDF Core Strategy 2012.
