Main issues, as the Inspector framed them

Whether the development would preserve or enhance the character or appearance of the Spring Grove Conservation Area
The effect of the proposal on highway safety for users of Thornbury Avenue

What decided it

The development fails to preserve or enhance the character and appearance of the Spring Grove Conservation Area through its obtrusive boundary treatment, extensive rendering, dark fenestration, and loss of original architectural detailing, with no public benefits to outweigh this less than substantial harm.

Plan policies cited: Policy CC1, Policy CC2, Policy CC4, Policy SC7, Policy EC2, Policy EC2(e)

- Heritage. Listed buildings by grade and distance, conservation areas, scheduled monuments, registered parks and gardens, heritage at risk.
- 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.
