Main issues, as the Inspector framed them
- The effect of the proposed side and rear extensions on the living conditions for the occupiers of No. 129B Cottimore Lane as regards outlook
What decided it
The main outlook from the neighbouring property's habitable rooms is through windows where the 45-degree test is satisfied, and the rear garden has limited amenity value, therefore the extensions would not have a materially adverse effect on outlook.
