Site constraints 8

Grade II listed: Mullyon House
List entry 1158161 · 1 m away · 6 more listed buildings within 150 m (1 Grade I, 5 Grade II)
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.
Show the other 6 with distances
Historic England ↗
Cornwall 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.
Public footpath 12 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.
Heritage coast: The Lizard
A defined stretch of undeveloped coastline.
Development inconsistent with keeping the coast undeveloped is resisted.
Scheduled monument 52 m away: Churchyard cross in St Melaine's churchyard
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 ↗
Also on the record
Radon affected area, class 4; Inside the Mullion 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
