Site constraints 10

Local nature reserve 19 m away: Nunhead Cemetery
Work nearby can need a habitats assessment.
Harm to a protected site is only accepted where there is no alternative and an overriding public interest.
Archaeological priority area: North Southwark and Roman Roads
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: Southwark 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 ↗
Registered park or garden 20 m away: Nunhead Cemetery (All Saints)
Its setting is a consideration for work nearby.
Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.
Historic England ↗
Conservation area 19 m away: Nunhead Cemetry
The edge of the area; work outside it can still affect its setting.
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 ↗
Also on the record
Heritage at risk 19 m away: Nunhead Cemetery, Nunhead; Inside the Southwark built-up area; Priority habitat 22 m away: Deciduous woodland; Designated open space 24 m away; Metropolitan Open Land 47 m away.
Not affected
Outside flood zones 2 and 3 · Not green belt · No listed building at the site

Checked on 11 September 2026. Historic England, the Environment Agency, Natural England and council datasets, Open Government Licence. A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
