Main issues, as the Inspector framed them
- Whether the proposed development would preserve or enhance the character or appearance of the Conservation Area
What decided it
The high eaves and ridge of the proposed first floor extension combined with two dormer windows would dominate the main dwelling and fail to preserve or enhance the character or appearance of the Conservation Area, and the limited public benefits would not outweigh this less than substantial harm.

- Development plan policies
- Policy HQ/1Policy NH/14
- National Planning Policy Framework
- Paragraph 215
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.
