Main issues, as the Inspector framed them
- the effect of the proposed development on the character and appearance of the appeal building and area
- the living conditions of the occupants of 7 Seaton Road, with particular regard to privacy
What decided it
The dormer's design respects the proportions of the host building and would not be dissimilar to other dormer windows in the street scene, while the window positioning prevents harmful overlooking to the neighbouring property's garden.

- Development plan policies
- CS11CS12
- National Planning Policy Framework
- Paragraph 135
