Site constraints 11

Royal Hospital 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 - No 100. Named permitted development rights are withdrawn here.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.
In flood zones plus climate change
Inside the extent flood zones 2 and 3 could reach with climate change: the Central allowance for the 2080s on rivers, the Upper End allowance for sea level rise to 2125. From the sea. Defences are not counted.
The Environment Agency flood map for planning. Councils use it to decide when a flood risk assessment and the sequential test are needed. It is indicative and does not show whether a particular property will flood.
Flood map ↗
Tree preservation order
Consent is needed before work on protected trees.
Not every council has published its orders as open data, so no order shown is not proof there is none.
Air quality management area: Kensington and Chelsea 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 about 350 m away: Thames Tideway Tunnel
The site is about 350 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, about 697 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 ↗
11 listed buildings within 150 m of the postcode pin
Nearest: 9-37, Shawfield Street Sw3, Grade II, about 20 m from the postcode pin · 1 Grade II*, 9 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 11 with distances
Historic England ↗
Also on the record
Registered park or garden about 241 m away: St Luke's Garden; Inside the Kensington and Chelsea built-up area; Public transport access: PTAL 5 (very good), TfL 2023, for the 100 m square; Town centre about 30 m away: King's Road (east).
Not affected
Outside flood zones 2 and 3 · Not green belt · No scheduled monument at the site

Checked on 6 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.
