Main issues, as the Inspector framed them
- The effect of the proposed development upon the character and visual appearance of the street scene and the surrounding area
What decided it
The combination of the modest scale, depth and design of the proposed extension, the retained 777mm gap to the side boundary, and the absence of side extensions to the neighbouring property would be sufficient to avoid material harm to the character and appearance of the street scene.
What the Inspector cited
- Development plan policies
- Policy JP-P1 of the Places for Everyone Joint Development Plan
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.
