Main issues, as the Inspector framed them

whether the proposal would be inappropriate development in the Green Belt having regard to the National Planning Policy Framework and any relevant development plan policies
the effect of the proposal on the openness of the Green Belt
if the proposal is inappropriate development, whether the harm by reason of inappropriateness, and any other harm, would be clearly outweighed by other considerations so as to amount to the very special circumstances required to justify the proposal

What decided it

The proposal would result in a clearly disproportionate addition to the original building (179% increase versus the 50% guideline) and would harm the openness of the Green Belt, with no very special circumstances to justify the inappropriate development.

Framework references: 154

Plan policies cited: Policy SADM 34

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.
