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 December 2023 (NPPF) and any relevant development plan policies
The effect of the proposal on the openness of the Green Belt
The effect of the proposal on the character and appearance of the area around Hawkshead Lane
If inappropriate, would the harm by reason of inappropriateness, and any other harm, be clearly outweighed by other considerations so as to amount to the very special circumstances required to justify the proposal

What decided it

The cumulative effect of successive extensions resulting in the dwelling already exceeding the 50% disproportionality threshold, combined with the proposed carport adding further inappropriate development to the Green Belt without very special circumstances to justify it.

Framework references: 152, 153, 154

Plan policies cited: Policy SADM34, Policy SP9

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.
