Site constraints 11

Flood zone 3, rivers and sea
High chance: a 1 in 100 or greater annual chance from rivers, or 1 in 200 from the sea. Any development here needs a flood risk assessment. Defences are not counted.
The Environment Agency flood map for planning. Homes in zone 3 must also pass the sequential test. Surface water flooding is a separate map.
Flood map ↗
Pimlico 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 Named permitted development rights are withdrawn here.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.
Archaeological priority area: City of Westminster APA 3.2
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: 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 ↗
National infrastructure project 238 m away: Thames Tideway Tunnel
The site is 238 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, 187 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 ↗
17 listed buildings within 150 m
Nearest: 29-49, St George's Drive Sw1, Grade II, 6 m away · 1 Grade II*, 16 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 17 with distances
Historic England ↗
Central activities zone
The core of central London in the London Plan.
Offices, culture and the other strategic functions of the centre take priority over new housing here.
Registered park or garden 95 m away: Eccleston 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
Inside the City of Westminster built-up area; Public transport access: PTAL 6a (excellent), TfL 2023, for the 100 m square.
Not affected
Not green belt · No scheduled monument at the site
