Main issues, as the Inspector framed them
- the effect of the proposal on the character and appearance of the area, including its effect on trees
- whether the proposal would provide an adequate standard of accommodation for future occupiers, with particular regard to outlook, sunlight and daylight
What decided it
The substantial harm to protected trees with high amenity value and the inadequate standard of accommodation in the rear bedroom, particularly the severely limited outlook and low sunlight levels, could not be outweighed by the housing delivery benefits despite the Council's inability to demonstrate a five-year housing supply.
The substantial positive weight afforded to housing delivery on previously developed land was insufficient to outweigh the substantial harm identified in respect of safeguarding trees and the standard of accommodation proposed; the adverse impacts significantly and demonstrably outweighed the benefits when assessed against the Framework as a whole, displacing the presumption in favour of sustainable development.
