Main issues, as the Inspector framed them

Whether the proposal would preserve or enhance the character or appearance of the Belgravia Conservation Area

What decided it

The mansard roof extensions would fail to preserve or enhance the character and appearance of the Belgravia Conservation Area through their excessive scale and bulk, and the moderate public benefits were insufficient to outweigh the less than substantial heritage harm.

Framework references: 208

Plan policies cited: Policy 38, Policy 39, Policy 40, Policy 8, Policy D3

- Landscape and environment. Green belt, national parks and national landscapes, SSSIs, ancient woodland, SPA, SAC and Ramsar sites, nutrient catchments.
- Flooding. Flood zones 2 and 3, surface water, and both again with climate change.
- Transport. The 800 metre station catchment and service frequency, bus stops with their weekday frequency, the cycle network, and the Framework’s transport tests measured for the site.
