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.

Historic England ↗

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 ↗

Borough High Street 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 ↗

2 Article 4 directions

Bankside and Borough District Town Centre · Central Activities Zone. Named permitted development rights are withdrawn here.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

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: Southwark 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 ↗

Town centre: Bankside and The Borough

A designated centre in the London Plan.

Shops, services and active frontages are protected in centres, and main town centre uses are steered here first.

National infrastructure project 339 m away: Thames Tideway Tunnel

The site is 339 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, 10 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 ↗

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.

Opportunity area

Where the London Plan expects significant growth.

Boundaries are indicative and the borough holds the detailed plan.

Also on the record

Wider setting of protected view 1A.2 Alexandra Palace viewing terrace to St Paul's Cathedral; Inside the Southwark built-up area; Public transport access: PTAL 6b (excellent), TfL 2023, for the 100 m square; Tree preservation order 30 m away: 199 Borough High Street London Southwark SE1 1HR.
