Main issues, as the Inspector framed them
- whether the proposal makes adequate provision for any additional need of social rented, intermediate homes and open space arising from the development
- whether the proposal would provide acceptable living conditions for future occupants, with regard to noise and disturbance and cooking smells
- whether the proposal would provide acceptable standards of fire safety
- the effect of the proposal on the character and appearance of 249-251 Old Kent Road and whether it would preserve or enhance the character or appearance of the conservation area
What decided it
The proposed mansard roof extension would harm the significance of the non-designated heritage assets and conservation area by destroying the original butterfly roof and disrupting the continuous terrace rhythm, and this heritage harm was not outweighed by the modest public benefit of providing a single additional flat.
