Main issues, as the Inspector framed them

Whether the Council's refusal to grant a certificate of lawful use or development was well-founded

What decided it

The outbuilding was not demonstrated to be genuinely subordinate and reasonably required for purposes incidental to the enjoyment of the dwellinghouse, and the evidence regarding ground levels and height compliance with GPDO restrictions was not sufficiently precise and unambiguous.

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.
