Site constraints 6

Agricultural land, grade 2, surveyed
Best and most versatile land (grades 1, 2 and 3a). Source: Natural England's post-1988 ALC field survey (Reading).
Where development of farmland is needed, policy prefers poorer land over the best and most versatile (grades 1, 2 and 3a). Three sources: Natural England's post-1988 field surveys, which are definitive where they exist; the Defra predictive map for England (2025) and the Welsh Government predictive map, modelled from the soil map with 3a and 3b split; and the 1970s provisional map, which planners and other services still show, coarser and with grade 3 undivided. Where the provisional and predicted grades disagree, treat the predicted grade as the current estimate and expect an application to carry its own survey.
Survey report ↗
Registered park or garden about 28 m away: Ditton Park
Its setting is a consideration for work nearby.
Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.
Historic England ↗
Habitat network: Network Enhancement Zone 1
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
National infrastructure project about 812 m away: M4 Junctions 3 to 12 Smart Motorway
The site is about 812 m from the project boundary. Highway, decided. The project page says whether consent was granted. Also within 2 km: Expansion of Heathrow Airport (Third Runway) (at pre-application, about 1121 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.
Planning Inspectorate project page ↗
Also on the record
Inside the Slough built-up area; Green belt about 29 m away: London.
Not affected
Outside flood zones 2 and 3 · 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, 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.
