Site constraints 11

Grade II listed: The Windmill Public House
List entry 1281291 · The pin is inside its outline · 9 more listed buildings within 150 m (9 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 9 with distances
Historic England ↗
Green belt: London
Inappropriate development needs very special circumstances.
Green belt policy allows a short list of exceptions, such as limited extensions and replacement buildings. Anything else needs very special circumstances that clearly outweigh the harm. Some green belt land can count as grey belt, where it does not strongly serve the green belt's purposes. The council decides this in its green belt assessment or on each application, so we do not mark it here.
Read the government guidance ↗
Public footpath 5 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.
Thundridge Wadesmill 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.
Council document ↗
Habitat network: Network Enhancement Zone 1
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Also on the record
Radon affected area, class 2; Registered park or garden 207 m away: Youngsbury; Inside the Thundridge and Wadesmill built-up area; Priority habitat 12 m away: No main habitat but additional habitats present; Open access land 4 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.; 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 · No scheduled monument at the site
