Site constraints 6

Suffolk Coast & Heaths 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: Suffolk

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 294 m away: Outer Thames Estuary

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 362 m away: Sizewell Marshes SSSI; Inside the Sizewell built-up area.

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.
