Site constraints 7

Air quality management area: Tower Hamlets 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 ↗
Local nature reserve 128 m away: Tower Hamlets Cemetery Park
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.
National infrastructure project 333 m away: Thames Tideway Tunnel
The site is 333 m from the project boundary. Waste water treatment, decided. The project page says whether consent was granted.
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 ↗
3 listed buildings within 150 m
Nearest: Professional Development Centre (Formerly South Grove School), With Associated Handicraft/Woodwork Block, Boundary Wall and Iron Gates, 39 m away · 1 Grade II
The site itself is not listed. Listed building consent is needed for work that affects the special interest of a listed building, inside or out, on top of planning permission. Setting can be a consideration for buildings nearby; there is no fixed radius.
Show all 3 with distances
Conservation area 14 m away: Ropery Street
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.
Also on the record
Inside the Tower Hamlets built-up area; Public transport access: PTAL 6a (excellent), TfL 2023, for the 100 m square.
Not affected
Outside flood zones 2 and 3 · Not green belt · No scheduled monument at the site

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