Site constraints 6

Belsize conservation area
Demolition needs planning permission and permitted development is restricted.
The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
Council document ↗
4 Article 4 directions
13-51 (odd) & 16-60 (even) Belsize Avenue · Belsize Conservation Area Non-immediate Article 4 · Belsize Conservation Area (various properties) · Basements. Named permitted development rights are withdrawn here.
An Article 4 direction withdraws particular permitted development rights, so work that would normally need no application needs one here. Not every council has published its directions.
Air quality management area: Camden AQMA
The council has declared the area as failing an air quality objective.
Schemes that add traffic, parking or combustion plant are assessed against the area's action plan and may need an air quality assessment.
Council record ↗
Also on the record
8 listed buildings within 150 m of the postcode pin; Inside the Camden built-up area; Public transport access: PTAL 4 (good), TfL 2023, for the 100 m square.

Checked on 18 October 2026. The pin for this application is the centre of its postcode rather than the building, so distances to nearby designations are measured from the postcode and can be out by the width of the postcode area.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
