Main issues, as the Inspector framed them
- The effect of the proposal on the living conditions of the occupiers of the neighbouring property, No.56, with particular regard to outlook and light
What decided it
The proposed extension would breach the 45-degree line and significantly restrict the outlook and light to the neighbouring property's first-floor window, contrary to Policy 29 and SPD 4, and the modest practical benefits do not outweigh this harm.
What the Inspector cited
- Development plan policies
- Policy 29 of the Sutton Local PlanSPD 4 Design of Residential Extensions
How the Inspector dealt with each one is set out in the app, in order: the development plan, national policy, housing land supply, other considerations and the planning balance, beside the letter.
