Main issues, as the Inspector framed them

The effect of the development on the character and appearance of the host building, the adjoining terrace, and the Camden Town Conservation Area

What decided it

The development would cause less than substantial but important harm to the character and appearance of the conservation area and listed building, with no public benefits of sufficient weight to outweigh that harm.

The less than substantial harm to the significance of the conservation area and listed building was not outweighed by the minimal public benefits of additional residential accommodation and use of airspace, resulting in dismissal.

Framework references: 60, 120, 202

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.
