Main issues, as the Inspector framed them
- the effect of the proposed development on the character and appearance of the property and the surrounding area, with reference to the proposed external staircase and railings to the outdoor amenity space
- whether the proposed development would meet sustainable transport requirements, with reference to the proposed cycle parking provision
- whether the proposed development would provide adequate living conditions for the future occupiers, with reference to the size of the internal floor area
- whether the proposed development would provide adequate living conditions for the future occupiers, with reference to the provision of outdoor amenity space
What decided it
The cumulative effect of conflicts with the development plan on character and appearance, sustainable transport, and internal space standards, combined with the limited housing contribution, meant the adverse impacts significantly and demonstrably outweighed the benefits under paragraph 11(d) of the Framework.
The limited positive contribution to housing supply and mix was significantly and demonstrably outweighed by the adverse impacts on character and appearance, sustainable transport provision, and living conditions (internal space), assessed against the policies of the Framework taken as a whole.
