Flood zone 2, rivers and sea
Medium chance: between a 1 in 100 and 1 in 1,000 annual chance from rivers, or 1 in 200 to 1 in 1,000 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.

Protected view corridor: 5A.2 Greenwich Park Wolfe statue to St Paul's Cathedral
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 wider setting of 4A.1 Primrose Hill summit to St Paul's Cathedral; 6A.1 Blackheath Point 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.
London View Management Framework ↗
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, about 378 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 ↗
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: City of London 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 ↗

Checked on 14 October 2026. The pin for this application is the centre of its postcode rather than the building, so distances to nearby designations are measured from the postcode and can be out by the width of the postcode area. Historic England, the Environment Agency, Natural England, the Planning Inspectorate, Transport for London (public transport access levels, Powered by TfL Open Data, OGL v3.0, contains OS data © Crown copyright and database right 2025) and council datasets, Open Government Licence. A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
