Site constraints 5

National landscape 28 m away: Chilterns

Outside the landscape; its setting can still be raised.

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.

Also on the record

Inside the Marlow built-up area; Green belt 22 m away: London; Open access land 45 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.; the 1970s provisional farmland map 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 · No listed building at the site · No scheduled monument 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.
