Site constraints 12

Blackheath 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 ↗
Archaeological priority area
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: Greenwich 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 ↗
National infrastructure project 83 m away: Thames Tideway Tunnel
The site is 83 m from the project boundary. Waste water treatment, decided. The project page says whether consent was granted. Also within 2 km: Silvertown Tunnel (decided, 1252 m); London Strategic Heat Main Project (at pre-application, 77 m).
Nationally significant infrastructure projects (power stations, electricity lines, pipelines, major roads and railways, harbours, airports and reservoirs) are consented by a Secretary of State under the Planning Act 2008, after an examination by the Planning Inspectorate, rather than by the council. The boundary is the one the Inspectorate consults on and can change as the scheme does. Projects are shown within 2 km of the site.
Planning Inspectorate project page ↗
World heritage site 35 m away: Maritime Greenwich
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 ↗
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Scheduled monument 158 m away: Greenwich Palace
Its setting is a consideration for work nearby.
Nationally important archaeology protected by the Secretary of State. Work that affects the monument or its setting is rarely permitted.
Historic England ↗
Also on the record
8 listed buildings within 150 m; Radon affected area, class 2; Inside the Greenwich built-up area; Public transport access: PTAL 4 (good), TfL 2023, for the 100 m square; Town centre 52 m away: East Greenwich.
Not affected
Outside flood zones 2 and 3 · Not green belt
