Main issues, as the Inspector framed them

Whether the proposed dormer window would preserve or enhance the character or appearance of the Castelnau Conservation Area, having particular regard to the effect on the significance of a Building of Townscape Merit

What decided it

The proposed dormer's form, design and scale would be incongruous with the host building's diminishing scale at roof level and would harm the significance of the Building of Townscape Merit and the character of the Conservation Area, with no public benefits to outweigh this harm.

Framework references: 197, 202

Plan policies cited: Policy LP1, Policy LP3, Policy LP4

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.
