Grade I listed: 11, Downing Street Sw1
List entry 1356989 · The pin is inside its outline · 15 more listed buildings within 150 m (6 Grade I, 2 Grade II*, 7 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.

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.
Whitehall 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.
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 Named permitted development rights are withdrawn here.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.
Protected view corridor: 2A.2 Parliament Hill summit to the Palace of Westminster
Inside the landmark viewing corridor of a protected vista. A building that rises above the corridor's threshold height should be refused. How high that is depends on where along the view the site is. Also in the corridor of 2B.1 Parliament Hill oak tree to the Palace of Westminster; 4A.2 Primrose Hill summit to the Palace of Westminster; 9A.1 King Henry's Mound to St Paul's Cathedral.
The London Plan (policy HC4) designates strategic views, and the Mayor's London View Management Framework (March 2012) gives 13 of them a protected vista toward St Paul's Cathedral, the Palace of Westminster or the Tower of London. A vista has a threshold height that rises or falls with the line of sight. In the landmark viewing corridor, a building above it would harm the view and should be refused. In the wider setting consultation area around the corridor, a building above it is referred for consultation and its effect on the view is judged. The threshold changes along each view and is set out in the framework. A revised framework is out for consultation until 4 December 2026 and is not yet in force.
National infrastructure project: Thames Tideway Tunnel
The site is inside 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, 409 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.
Archaeological priority area: City of Westminster APA 1.1
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.
Registered park or garden 26 m away: St James's Park
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.
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
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.
Also on the record
Inside the City of Westminster built-up area; Public transport access: PTAL 6b (excellent), TfL 2023, for the 100 m square; Metropolitan Open Land 90 m away.
