Site constraints 11

Green belt: London
Inappropriate development needs very special circumstances.
Green belt policy allows a short list of exceptions, such as limited extensions and replacement buildings. Anything else needs very special circumstances that clearly outweigh the harm. Some green belt land can count as grey belt, where it does not strongly serve the green belt's purposes. The council decides this in its green belt assessment or on each application, so we do not mark it here.
Read the government guidance ↗
Coppermill Lock conservation area
Also Coppermill Lock, Copper Mill Lock. 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.
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 rivers. 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 ↗
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
SSSI about 128 m away: Mid Colne Valley SSSI
Natural England may need consulting, depending on what is proposed.
Sites of special scientific interest are the best wildlife and geological sites in the country. Development likely to harm one is rarely permitted.
Also on the record
Radon affected area, class 2; Flood defence about 18 m from the postcode pin (wall, designed for a 1 in 100 year flood); 1 listed building within 150 m of the postcode pin; Inside the Hillingdon built-up area; Public transport access: PTAL 1a (very poor), TfL 2023, for the 100 m square; National infrastructure project about 1294 m away: Expansion of Heathrow Airport (Third Runway), at pre-application.
Not affected
Outside flood zones 2 and 3 · No scheduled monument at the site

Checked on 16 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.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
