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 relevant development plan policies

What decided it

The modest increase in built volume (22%) relative to the original building, combined with the building's location and screening, means the proposal does not constitute disproportionate additions and therefore complies with NPPF paragraph 149(c).

Framework references: 137, 149, 54

Plan policies cited: Policy GB1, Policy GB10

- 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.
