Main issues, as the Inspector framed them
- the effect of the proposal on the provision of family-sized dwellings in the Borough
- whether the proposal would provide acceptable living conditions for future occupants, with regard to internal space, private outdoor amenity space, and privacy
What decided it
The proposal's failure to provide acceptable living conditions for future occupants, particularly the inadequate internal space, lack of suitable private outdoor amenity space, and poor privacy standards, combined with the loss of a family-sized dwelling that Policy H(b) seeks to protect, means the harm significantly and demonstrably outweighs the benefits even in the context of housing land supply shortfall.
The adverse impacts of the proposal—loss of family-sized dwelling and unacceptable living conditions—significantly and demonstrably outweigh the moderate benefits of one additional dwelling and efficient use of an existing building, such that the presumption in favour of sustainable development does not apply.
