Main issues, as the Inspector framed them
- The effect of the proposal on the character and appearance of the host building and whether it would preserve or enhance the character or appearance of the Kensington Conservation Area
- The effect of the proposal on the living conditions of the occupiers of 68 and 72 Hornton Street, with particular regard to outlook and natural light
What decided it
The upper ground floor element would be an overly prominent and incongruous addition that would jar with the appearance of the terrace and result in less than substantial harm to the conservation area, with no public benefits to outweigh this harm.
