Main issues, as the Inspector framed them
- The effect of the proposal on the character and appearance of the host property and the area
What decided it
The proposal would significantly harm the character and appearance of the host property and the area by introducing a large, incongruous lightwell and external staircase that would be markedly at odds with the established rhythm and cohesion of the streetscene, and this harm would not be outweighed by the internal benefits to the basement.
What the Inspector cited
- Development plan policies
- Policy PLAN1 of the Islington Local Plan Strategic and Development Management Policies 2023
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.
