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
Whether harm by reason of inappropriateness would be clearly outweighed by other considerations and if so whether this would amount to the very special circumstances required to justify the proposal

What decided it

The cumulative disproportionate increase in the size of the dwelling (153.8% over the original) combined with the reduction in Green Belt openness could not be outweighed by the moderate benefits of the proposal, and no very special circumstances existed to justify the inappropriate development.

Framework references: 137, 138, 147, 149

Plan policies cited: Policy RA3

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.

Every English appeal since 2016, with the letter behind it wherever the Inspectorate published one. Searched by meaning as well as by words, with the key case law counted live across the letters.

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.
