Site constraints 5

Chilterns 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.
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
SSSI about 197 m away: Bear, Oveys & Great Bottom Woods SSSI
Natural England may need consulting, depending on what is proposed.
Sites of special scientific interest are the best wildlife and geological sites in the country. Development likely to harm one is rarely permitted.
Also on the record
Priority habitat about 34 m away: Deciduous woodland; Open access land about 35 m away: Access Land - Combined Open Country, Registered Common Land and Section 16 Dedicated Land. MoD Byelaw, Section 28 Exclusions, Racecourses and Aerodromes and ECP Margin have been removed..
Not affected
Outside flood zones 2 and 3 · Not green belt · No scheduled monument at the site

Checked on 24 September 2026.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
