Site constraints 6

Cornwall National Landscape
Great weight to conserving the landscape; major development restricted.
Previously an area of outstanding natural beauty, which is still the designation in law. Since 2023 authorities must seek to further its purpose, not merely have regard to it.
Heritage coast: The Roseland
A defined stretch of undeveloped coastline.
Development inconsistent with keeping the coast undeveloped is resisted.
Habitat network: Network Expansion Zone
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Radon affected area, class 5
An estimated 10 to 30% of homes reach the radon action level. Indicative for the 1 km square, which takes the highest class found in it; a radon test gives the answer for a building.
From the British Geological Survey and UK Health Security Agency indicative atlas. Under building regulations, as the BRE guide BR 211 (2023) sets out, new buildings and extensions need basic radon protection from class 3 in England and Wales and from class 2 in Scotland, and full protection from class 5. The class at the site itself, from the detailed BGS map, decides which.
UKHSA radon ↗
Also on the record
Inside the Gorran Haven built-up area; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 3, but it predates the buildings here and the current map does not class it as farmland.
Not affected
Outside flood zones 2 and 3 · Not green belt · No listed building at the site

Checked on 6 October 2026. Historic England, the Environment Agency, Natural England, the British Geological Survey and UK Health Security Agency (radon, contains BGS materials © UKRI) 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.
