Site constraints 4

National park about 31 m away: South Downs
Outside the park; its setting can still be raised.
Landscape, scenic beauty and wildlife carry great weight, and major development is only allowed in exceptional circumstances.
1 listed building within 150 m of the postcode pin
Nearest: Gurrs Croft, Grade II, about 40 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
Inside the Hassocks and Hurstpierpoint 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. 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.
