Main issues, as the Inspector framed them
- The effect of the proposed development on the character and appearance of the existing dwelling and on the street scene
What decided it
The proposed two storey side extension would create an unacceptably tight gap between properties resulting in a terracing effect out of character with the locality, and the overall scheme would present a very bulky, visually discordant form that would overwhelm the existing property and appear visually intrusive in the street scene.
What the Inspector cited
- Development plan policies
- Policy QD7Policy QD9
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.
