Site constraints 7

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 80 m away: Fal & Helford
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.
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Also on the record
SSSI 289 m away: Lower Fal & Helford Intertidal SSSI; Inside the St Mawes built-up area; the 1970s provisional farmland map 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 11 September 2026. Historic England, the Environment Agency, Natural England 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.
