Main issues, as the Inspector framed them
- whether the proposed development would preserve or enhance the character or appearance of the Underhill Conservation Area

What decided it
The proposed development would cause less than substantial but considerable harm to the significance of the conservation area and unacceptable harm to the living conditions of neighbouring occupiers through overbearing impact and loss of privacy, with public benefits insufficient to outweigh these harms.

- Policy ENV4Policy ENV12Policy ENV16Policy Port/EN7
