Site constraints 5

National infrastructure project about 78 m away: The Sizewell C Project

The site is about 78 m from the project boundary. Generating station, decided. The project page says whether consent was granted. Also within 2 km: East Anglia ONE North Offshore Windfarm (decided, about 301 m); East Anglia TWO Offshore Windfarm (decided, about 301 m); Galloper Offshore Wind Farm (decided, about 1023 m).

Nationally significant infrastructure projects (power stations, electricity lines, pipelines, major roads and railways, harbours, airports and reservoirs) are consented by a Secretary of State under the Planning Act 2008, after an examination by the Planning Inspectorate, rather than by the council. The boundary is the one the Inspectorate consults on and can change as the scheme does. Projects are shown within 2 km of the site.

Habitat network: Network Expansion Zone

Where habitat is joined up enough to work as a network. Context, not a constraint on its own.

Also on the record

Inside the Leiston built-up area; Priority habitat about 38 m away: Deciduous woodland; 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 scheduled monument at the site

Checked on 17 October 2026. The pin for this application is the centre of its postcode rather than the building, so distances to nearby designations are measured from the postcode and can be out by the width of the postcode area. Historic England, the Environment Agency, Natural England, the Planning Inspectorate 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.
