Site constraints 4

Scheduled monument about 133 m away: Montem Mound: a motte at Salt Hill, Upton-cum Chalvey
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 ↗
National infrastructure project about 948 m away: M4 Junctions 3 to 12 Smart Motorway
The site is about 948 m from the project boundary. Highway, decided. The project page says whether consent was granted. Also within 2 km: Slough Multifuel Extension Project (decided, about 1858 m).
Nationally significant infrastructure projects (power stations, electricity lines, pipelines, major roads and railways, harbours, airports and reservoirs) are consented by a Secretary of State under the Planning Act 2008, after an examination by the Planning Inspectorate, rather than by the council. The boundary is the one the Inspectorate consults on and can change as the scheme does. Projects are shown within 2 km of 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, the Planning Inspectorate 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.
