Site constraints 13
Registered battlefield: Battle of Barnet 1471
Nationally designated heritage. Its significance and setting carry great weight.
Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.
Monken Hadley 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.
2 Article 4 directions
Article 4(2) for Monken Hadley CA Area 3 · Article 4 Small Houses in Multiple Occupation (HMO) Area 1. Named permitted development rights are withdrawn here.
An Article 4 direction withdraws particular permitted development rights, so work that would normally need no application needs one here. Not every council has published its directions.
Archaeological priority area
An assessment or field evaluation may be asked for before ground works.
The council or Historic England considers archaeology likely here. A desk-based assessment, and sometimes trial trenching, can be asked for with the application.
Air quality management area: Barnet AQMA
The council has declared the area as failing an air quality objective.
Schemes that add traffic, parking or combustion plant are assessed against the area's action plan and may need an air quality assessment.
10 listed buildings within 150 m
Nearest: King William Iv Public House, Grade II, 16 m away · 10 Grade II
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.

Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Also on the record
Tree preservation order 19 m away: The London Borough of Barnet (Monken Hadley Conservation Area) Tree Preservation Order 1972 (Parts A, B, C, D, E and 37 and 43 Dury Road and Hadley Lodge Hadley Common) made under The Town and Country; Inside the Barnet built-up area; Public transport access: PTAL 1a (very poor), TfL 2023, for the 100 m square; Green belt 27 m away: London; Priority habitat 45 m away: Deciduous woodland; 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
