Main issues, as the Inspector framed them

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

What decided it

The cumulative effect of the proposed extension combined with previous extensions would result in a disproportionate addition to the original building (198% increase in floorspace), failing to meet the exception in NPPF paragraph 154(c) and constituting inappropriate development in the Green Belt that is not justified by very special circumstances.

Framework references: 154

Plan policies cited: Policy CS5, Policy 22

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.
