Site constraints 10

Dorset 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.
2 Article 4 directions
Bridport to LymeRegis 2 · Bridport to LymeRegis 1. Named permitted development rights are withdrawn here.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.
Heritage coast: West Dorset
A defined stretch of undeveloped coastline.
Development inconsistent with keeping the coast undeveloped is resisted.
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Special area of conservation 249 m away: Sidmouth to West 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.
Also on the record
SSSI 249 m away: Chesil & The Fleet SSSI; Conservation area 50 m away: Charmouth Conservation Area; World heritage site 238 m away: Dorset and East Devon Coast; Inside the Charmouth 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 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.
