Planning Permission in Harefield | Fixed-Fee Plans

No Article 4 Direction covers Hillingdon, which keeps the Harefield permitted-development route open on unlisted houses. Harefield reads as village conservation, rural fringe, and that is the context a UB9 scheme is judged in. Hillingdon carries 29 conservation areas; if the UB9 address falls in Northwood or Harefield, expect the permitted-development route to close and a full Hillingdon Council application to be the faster answer. Whether a Harefield plot sits inside the boundary changes the whole route.

How Article 4 directions apply to your Harefield street is settled at survey stage, not after submission. What can be built on a Harefield plot is decided by the tudor and georgian fragments — the original rear wall position first, the Harefield Hospital roofline second. The borough policy layer over every UB9 address is set out on Hillingdon planning. The Harefield survey then carries into loft conversion drawings in Harefield if the project runs on to construction.

The Harefield clock does not start until London Borough of Hillingdon validates — one to two weeks. Nothing is drawn for a UB9 address until the existing building is measured.

Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.

London Borough of Hillingdon publishes the Harefield application online during consultation. Drawings for Harefield are supplied print-ready and in the format London Borough of Hillingdon accepts.

We would rather redesign a UB9 rear elevation than argue an objection. Roof pitch and eaves height on a Harefield house are measured, not scaled off.

On Harefield stock the party wall stage is routine and worth timetabling. Once consent is granted, house extension drawings follows for the UB9 property.

Harefield is characterised by tudor and georgian fragments, 1930s semi-detached, concentrated across UB9 in the Denham / Harefield area. A Harefield scheme is designed around what the tudor and georgian fragments can actually carry. What that means for a UB9 address: applications on Georgian stock here almost always need a heritage statement alongside the drawings. For a Harefield owner it decides the structural spec. The UB9 terrace sets the datum; departures from it show up in the officer report.

Digging under a Harefield house is a structural question before a planning one. If the UB9 job later needs architectural drawings for UB9 properties or building regulations drawings, the existing drawings already carry the measurements.

Getting to a Harefield survey

Surveyors travel to UB9 addresses from the studio; the nearest stations are Northwood, Uxbridge, Denham, Rickmansworth station. Appointments are booked in Harefield on weekdays and Saturdays, and the measured survey of a standard tudor and georgian fragments takes two to three hours.

Where Harefield sits

Harefield lies 17 miles (27 km) northwest of Charing Cross, on Ordnance Survey grid reference TQ055905, inside the Ruislip, Northwood and Pinner parliamentary constituency. Those coordinates matter in practice: a site location plan for Hillingdon Council must be drawn to a recognised scale over the correct grid square. Source.

Practical detail for a Harefield submission: access is via Northwood and Uxbridge and Denham and Rickmansworth station; the postal town here is UXBRIDGE; dialling code 01895; listed fabric nearby includes Grade II listed building. Site plans are drawn to the address as Hillingdon Council holds it.

Harefield postcode coverage

Coverage runs across UB9 (Denham / Harefield), which Harefield holds on its own — and Hillingdon Council validates against the address, so the district line matters more than the street name.

Streets and stations in Harefield

Most Harefield sites are within walking distance of Northwood or Uxbridge or Denham. and Grade II listed building is listed, which pulls neighbouring UB9 proposals into a setting assessment.

Chartered accountability applies to every UB9 drawing we issue. A tight Harefield plot — Harefield Hospital in the setting, a shared flank wall on UB9 — goes to Hillingdon Council for advice before it goes to determination.

Drawings are produced by chartered members of the Chartered Institute of Architectural Technologists (MCIAT), the professional body for technical design and building-regulations competence. First-time approval across our London caseload is 98%. Statutory fees shown are those in force in England in 2026 under the Town and Country Planning (Fees for Applications) Regulations.
