Planning Permission in Hillingdon | Fixed-Fee Plans

No Article 4 Direction covers Hillingdon, which keeps the Hillingdon permitted-development route open on unlisted houses. In Hillingdon the streetscape argument usually decides the case before the numbers do, because the area is 1930s semi-detached, post-war. Hillingdon has 29 conservation areas, and Northwood is the one that most often covers Hillingdon stock. The Hillingdon boundary position decides how much can be done under permitted development.

The Hillingdon Article 4 position is established at survey, before design. A Hillingdon survey establishes the 1930s semi-detached dimensions that decide the scheme — original rear wall, floor levels, and ridge height against Hillingdon Tube. The borough policy layer over every UB10 address is set out on Hillingdon planning. The Hillingdon survey then carries into architectural drawings in Hillingdon if the project runs on to construction.

Validation at London Borough of Hillingdon is the first delay a Hillingdon applicant meets. Nothing is drawn for a UB10 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.

A Hillingdon case only reaches committee if it draws significant objection. Every Hillingdon submission leaves here as a PDF set at the scales Hillingdon Council requires.

Objection volume on Hillingdon cases is public — we read it before advising. Party wall positions on a Hillingdon terrace are located during the survey.

Most Hillingdon terraces share a flank wall, so party wall notices apply. Once consent is granted, building regulations drawings follows for the UB10 property.

Hillingdon is characterised by 1930s semi-detached, concentrated across UB10 in the Hillingdon / Ickenham area. On Hillingdon streets the 1930s semi-detached sets the structural sequence — what can be opened up, where the load goes, how deep you can build. Reading that across to Hillingdon stock: on these 1930s semis the prior approval route often replaces a full application, and the drawing set is smaller as a result. In UB10 that determines the depth we can draw. The blocks around Hillingdon Tube set the prevailing eaves and ridge lines, and Hillingdon Council officers reference that rhythm when assessing height and massing on a Hillingdon street.

Subterranean work in Hillingdon has no dedicated borough policy behind it; the UB10 water table and the party walls are the real constraints. One Hillingdon survey serves loft conversion drawings for UB10 properties and house extension drawings too; we do not re-measure a UB10 property for each submission.

Getting to a Hillingdon survey

Surveyors travel to UB10 addresses from the studio; the nearest stations are Hillingdon, West Ruislip, Uxbridge. Appointments are booked in Hillingdon on weekdays and Saturdays, and the measured survey of a standard 1930s semi-detached takes two to three hours.

Where Hillingdon sits

Hillingdon lies 14.2 miles (22.8 km) west of Charing Cross, on Ordnance Survey grid reference TQ071827, inside the Uxbridge and South Ruislip parliamentary constituency. The UB10 block plan is set out from that grid square. Source.

Practical detail for a Hillingdon submission: surveyors travel in through Hillingdon and West Ruislip and Uxbridge; UXBRIDGE is the post town on Hillingdon addresses; dialling code 020. Site plans are drawn to the address as Hillingdon Council holds it.

Drawings for Hillingdon are issued under MCIAT charter, which is the technical design and construction-detailing qualification rather than an RIBA registration. If your Hillingdon site is tight — Hillingdon Tube in the setting, a Northwood designation, a shared flank wall — we test it with Hillingdon Council first rather than submit and hope.

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. Confirm your local authority at gov.uk and submission requirements on the Planning Portal. Studio: 71–75 Shelton Street, London WC2H 9JQ.
