Main issues, as the Inspector framed them
- whether the scheme would comply with policies which seek to retain family accommodation
- whether the scheme would ensure appropriate living conditions for the future occupants of the proposed accommodation, with particular regard to the rear garden space
- whether the proposal would make appropriate provision for biodiversity gain
- the effect of the proposal on the safety and convenience of highway users
- the effect of the proposal on the character and appearance of the area
What decided it
The cumulative conflicts with policies on family accommodation retention, living conditions, biodiversity gain and highway safety, combined with only limited positive weight for the modest housing contribution, meant the adverse impacts significantly and demonstrably outweighed the benefits even under the tilted balance.
the limited weight attached to the housing supply benefit was outweighed by moderate weight given to the loss of family accommodation, failure to ensure appropriate living conditions for Flat 6B, failure to address biodiversity requirements, and harm to highway safety, resulting in adverse impacts significantly and demonstrably outweighing the benefits
