Site constraints 11

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.
Aldbury 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.
Public footpath about 20 m away
Matters where it crosses or adjoins the site: obstructing a path without a diversion order is an offence, and work cannot start until the order is confirmed.
Compiled from highway authority data, not the legal definitive map. A few authorities have not published, so no path shown is not proof there is none.
Special area of conservation about 85 m away: Chilterns Beechwoods
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.
SSSI about 85 m away: Ashridge Commons and 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.
Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
1 listed building within 150 m of the postcode pin
Nearest: 28, Malting Lane, Grade II, about 31 m from the postcode pin
The site itself is not listed. Listed building consent is needed for work that affects the special interest of a listed building, inside or out, on top of planning permission. Setting can be a consideration for buildings nearby; there is no fixed radius.
Historic England ↗
Also on the record
Registered park or garden about 121 m away: Ashridge Estate; Radon affected area, class 2; Inside the Aldbury built-up area; 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 6 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.

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