Site constraints 8

Article 4 direction
Small HMO Northern Extension. Named permitted development rights are withdrawn here.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.
Archaeological priority area: The Lee place-name is associated with former woodland or a woodland clearance
An assessment or field evaluation may be asked for before ground works.
The council or Historic England considers archaeology likely here. A desk-based assessment, and sometimes trial trenching, can be asked for with the application.
Air quality management area: Lewisham 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 ↗
Conservation area about 18 m away: Blackheath
The edge of the area; work outside it can still affect its setting.

Checked on 7 October 2026.

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