Main issues, as the Inspector framed them
- the effect of the proposed development on the character and appearance of the area
- whether or not the proposed development would provide suitable living conditions for future occupiers, with particular regard to the provision of living and outdoor amenity space
What decided it
The harmful visual effect arising from the mansard extension's asymmetrical siting and incongruous form, which would interrupt the unbroken run of butterfly roofs characterising the terrace and conflict with policies requiring good design responsive to local context.
The benefits of increased internal accommodation and fire safety measures did not outweigh the harm to the character and appearance of the area.
