Main issues, as the Inspector framed them
- the effect on the character and appearance of the host building, the adjoining locally listed building and surrounding area, including the Ashburnham Triangle Conservation Area
- Whether sufficient parking would be provided
What decided it
The proposal accords with the development plan and would not harm the character and appearance of the host building, the locally listed building, or the conservation area, and would provide a useful small unit of residential accommodation in a sustainable location.
The benefits of providing a useful small unit of residential accommodation in a sustainable location outweighed any concerns, and the proposal was found to accord with the development plan, triggering approval under Framework paragraph 11(c) despite the Council's inability to demonstrate a five-year housing supply.
