Main issues, as the Inspector framed them

Whether or not the proposed development would preserve or enhance the character or appearance of the Harley Street Conservation Area

What decided it

The proposed linking corridor would result in loss of part of the historic bay window and disrupt the rear elevation's fenestration, causing less than substantial harm to the Conservation Area that was not justified by the public benefits, particularly given the availability of a fallback scheme.

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

- 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.
