Main issues, as the Inspector framed them
- the effect of the development on the character and appearance of the area, and on the significance of the High Town Conservation Area, through development within its setting
- whether the development would provide adequate living conditions for future occupiers, with particular regard to internal floor space and layout, noise and disturbance, privacy, the provision of outdoor space, refuse and recycling storage facilities and cycle parking and accessibility
- the effect of the development on the living conditions of the occupiers of nearby dwellings, with particular regard to outlook, privacy and noise and disturbance
- whether the development would satisfy the requirements of the statutory framework for biodiversity net gain
What decided it
The proposal's failure to respond appropriately to its context and provide adequate living conditions for future occupiers, combined with substantial weight attached to the conflict with Policy DP3 of the Framework, substantially outweighed the moderate benefits of housing delivery and brownfield reuse.
the benefits of housing delivery and brownfield redevelopment (moderate to substantial weight) were substantially outweighed by the substantial harm to character and appearance and failure to deliver acceptable living conditions for future occupiers
