Main issues, as the Inspector framed them

The effect of the proposed dormer window upon the character and appearance of the host building and the surrounding locality, with special attention to The Lake, Bushey Heath Conservation Area

What decided it

The proposed rear dormer window would unacceptably harm the character and appearance of the existing building and conservation area through its disproportionate bulk and dominance of the roof form, and the public benefits did not outweigh this heritage harm.

Framework references: 205, 206, 208

Plan policies cited: CS14, CS22, SADM29, SADM30

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.

Then the development plan position, the housing land supply as an Inspector last accepted it, and every appeal decided around the site with its letter.

Casework that chases the deadlines. Applications, appeals and conditions with their statutory dates.

The judgement stays yours. The tool gathers the material and dates it.
