Main issues, as the Inspector framed them

Whether the development would preserve or enhance the character or appearance of the Sheen Lane (Mortlake) Conservation Area, and whether it would harm its significance as a designated heritage asset

What decided it

The proposed extension would cause less than substantial harm to the conservation area's significance without clear and convincing justification or public benefits sufficient to outweigh that harm.

Framework references: 199, 200

Plan policies cited: Policy LP3

- 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.
