Site constraints 17

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 ↗
Elliot's Row 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
Central Activities Zone · Elephant and Castle Major Town Centre. Named permitted development rights are withdrawn here.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: 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: Elephant and Castle/ Walworth Road
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.
9 listed buildings within 150 m
Nearest: Numbers 25-28 and Attached Railings, Grade II, 13 m away · 8 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.

Historic England ↗
National infrastructure project 662 m away: Thames Tideway Tunnel
The site is 662 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, 290 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 ↗
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.
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 23A.1 Centre of Bridge over the Serpentine to the Palace of Westminster; Inside the Southwark built-up area; Public transport access: PTAL 6b (excellent), TfL 2023, for the 100 m square; Tree preservation order 21 m away: Imperial War Museum Annex, Austral Street, Se11 4SJ; Designated open space 42 m away; Priority habitat 47 m away: Traditional orchard; Metropolitan Open Land 94 m away.
