erection of a mansard roof extension

Inspector: Edwards J

Main issues, as the Inspector framed them

The effect of the development on the character and appearance of the host property as a non-designated heritage asset
Whether the proposal would preserve or enhance the character or appearance of the Westbourne Conservation Area

What decided it

The existing roof's lack of historic integrity due to prior alterations to the property, combined with the precedent of mansard roofs already present or permitted on neighbouring properties within the same street context, justified allowing the development as it would not harm the character and appearance of the conservation area.

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

What an account adds

Draw a red line around your site and the appraisal follows.
- 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.
