Inspector: Sylvester G

Main issues, as the Inspector framed them

Whether the proposal would be inappropriate development in the Green Belt having regard to any relevant development plan policies and the National Planning Policy Framework
The effect of the proposed development on the openness of the Green Belt
The effect of the proposed development on trees

What decided it

The cumulative visible increase in the footprint and volume of the building beyond 25%, particularly through the exposure of the basement as a lower ground floor storey via the sunken patio, constitutes disproportionate additions contrary to Policy DM18 and Framework Paragraph 154.c), and the resulting harm to Green Belt openness cannot be outweighed by other considerations.

Framework references: 154, 11

Plan policies cited: Policy DM18, Policy DM2, Policy DM6, Policy CS17

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.
