Site constraints 10

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.
Special area of conservation 34 m away: Falmouth Bay to St Austell Bay
Work nearby can need a habitats assessment.
Harm to a protected site is only accepted where there is no alternative and an overriding public interest.
Scheduled monument 97 m away: Early 20th century gun battery 150m north of St Mawes Castle
Its setting is a consideration for work nearby.
Nationally important archaeology protected by the Secretary of State. Work that affects the monument or its setting is rarely permitted.
Historic England ↗
Radon affected area, class 6
An estimated 30% or more 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 ↗
SSSI 169 m away: Lower Fal & Helford Intertidal 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
Conservation area 41 m away: St Mawes; 1 listed building within 150 m; Inside the St Mawes 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

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.
