Main issues, as the Inspector framed them

the effect of the development on the character and appearance of the host property and the surrounding area
the living conditions of local residents

What decided it

The development preserves the character and appearance of the host dwelling and surrounding area and does not negatively impact the living conditions of adjoining properties, thereby complying with the relevant provisions of the London Plan, the Local Plan, and the Residential Design Guidance SPD.

Plan policies cited: Policy D3 of the London Plan (LP) adopted March 2021, Policy CDH01 of the London Borough of Barnet Local Plan 2021-2036 (BLP) adopted in March 2025, Policy CDH05 of the London Borough of Barnet Local Plan 2021-2036 (BLP) adopted in March 2025

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.
