Site constraints 7

Bassingbourn conservation area
Demolition needs planning permission and permitted development is restricted.
The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
Council document ↗
Scheduled monument 22 m away: Bury Yard moated site adjacent to Milldyke
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 ↗
Habitat network: Other Priority Habitats - NEZ
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Also on the record
Inside the Bassingbourn built-up area; Tree preservation order 22 m away: Bassingbourn North End; Priority habitat 22 m away: Deciduous woodland; the 1970s provisional farmland map had this area as grade 2, 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.
