Site constraints 10

Grade II listed: Number 11 Including Mews Arch
List entry 1066453 · The pin is inside its outline · 16 more listed buildings within 150 m (2 Grade I, 5 Grade II*, 9 Grade II)
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 the other 16 with distances
Historic England ↗
Belgravia 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 ↗
Article 4 direction
Article 4 Basement Development Permitted Rights Removed. Named permitted development rights are withdrawn here.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: Westminster 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 ↗
Protected tree 9 m away: W644_T1, order W644
2 protected trees within 15 m. Named in a tree preservation order: work to it, its roots included, needs the council's consent first.
Root protection areas reach up to 15 m from a large tree, so an extension or new foundations this close usually needs a tree survey. Only some councils publish their single trees, and a position can be approximate: the order at the council is the definitive record, and no tree shown is not proof there is none.
Show all 2 trees with distances
Tree record ↗
National infrastructure project 702 m away: Thames Tideway Tunnel
The site is 702 m from the project boundary. Waste water treatment, decided. The project page says whether consent was granted. Also within 2 km: London Strategic Heat Main Project (at pre-application, the site is inside its boundary).
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 ↗
Registered park or garden 67 m away: The Grosvenor Estate: Eaton Square
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 ↗
Also on the record
Heritage at risk 73 m away: 112, Eaton Square; Inside the City of Westminster built-up area; Public transport access: PTAL 6b (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
