Measured Building Surveys · NW10 Willesden
NW10 borders the major Old Oak Park Royal regeneration; Brent applies suburban householder control across the residential streets.
If the project sits outside this district, the borough-wide page covers the rest: measured building surveys in Brent.
A measured building survey captures your Willesden property exactly — every wall, opening, level and boundary — as the accurate base for design and planning drawings. On NW10's older terraced and villa stock around Willesden, Harlesden, Kensal Green, Park Royal fringe, Willesden Green, walls are rarely square, so a laser-measured survey prevents costly errors before Brent Council ever sees the application.
Laser measurement with a Leica Disto, point clouds from a BLK360, output in AutoCAD and Revit, and MCIAT chartered throughout.
Across Willesden, Harlesden, Kensal Green, Park Royal fringe, Willesden Green in NW10, the dominant property is victorian and edwardian terraces, inter-war semis and substantial industrial-to-residential conversions across willesden, harlesden and kensal green. That stock shapes what measured building survey looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Brent Council judges each on design quality and neighbour impact. We survey the specific Willesden property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the NW10 streetscape.
Housing stock in NW10: Victorian and Edwardian terraces, inter-war semis, and a substantial body of former industrial buildings converted to housing, spread across Willesden, Harlesden and Kensal Green.
Within the district: Willesden, Harlesden, Kensal Green, Willesden Green, and the Park Royal fringe.
Streets we know in NW10: the Kensal Green terraces, Chamberlayne Road, Doyle Gardens and the Willesden Green streets. Each road has its own building line, boundary treatment and precedent that Brent Council weighs when assessing a measured building survey scheme.
Conservation areas: Kensal Green, Roundwood and Harlesden carry designation. Cross one of those boundaries and almost any change to the outside of the house becomes a full application, with a Heritage Statement attached.
Getting around NW10: Willesden Junction, Kensal Green and Willesden Green, on the Bakerloo, the Jubilee and the Overground.
Regeneration: Willesden sits within or alongside the Old Oak and Park Royal Opportunity Area, one of the largest in the UK, which sets the tone for local planning policy and for what officers expect of a design.
Property values: Land Registry price-paid data records a £580,000 median across 492 NW10 sales in 2025. That is the base an extension or loft is adding value on top of.
Borough character: Brent is among the most mixed boroughs in London. Queen's Park and Mapesbury carry heritage controls; Wembley is the regeneration engine at the other end of it.
A chartered technologist attends the Willesden address with laser and scanner in hand, a Disto for the dimensions and a BLK360 for the cloud. A two or three-bedroom terrace is normally captured in an hour and a half.
The drawing comes out of AutoCAD or Revit, scaled 1:50 or 1:100 and held to 3mm. Rooms, openings, fittings, service runs — each one annotated rather than implied.
All four elevations, plus sections cut through the building — the same drawings feed a Willesden planning submission, the party wall paperwork and the engineer's design.
Scanning with the BLK360 yields a complete 3D point cloud. That matters on NW10's period houses, on listed fabric, and anywhere the geometry has stopped being a set of rectangles.
Exports run to DWG, RVT, PDF and IFC. Whichever software your architect, contractor or structural engineer works in, the model opens without a conversion step.
Accuracy is reported to RICS standards — 3mm between any two points, 5mm against the site datum. A case officer, an insurer, or the party wall surveyor drafting an award will each accept that certificate.
Single planning or building-regs submission.
Planning + building regs + structural.
Listed, conservation or complex sites.
Yes. The Victorian and Edwardian terraces off Chamberlayne Road and around Doyle Gardens take side-return and rear extensions well, with lofts above them; outside the conservation areas much of that remains permitted development, and a Lawful Development Certificate puts the point beyond argument. The route gets settled first, then the drawings are made to Brent's checklist.
OPDC is one of the largest regeneration programmes in the country — tens of thousands of homes, plus an Elizabeth line and HS2 interchange — and it is lifting values across the district. For a house project it mostly changes the backdrop. Your scheme is still measured against permitted development limits and Brent's householder policy, and those are what we design to.
Usually yes — a rear dormer, or a hip-to-gable on the semis, kept inside the cubic-metre volume allowance and recorded with a Lawful Development Certificate. Kensal Green and Roundwood are the exception: inside those conservation areas the allowance does not apply at all. We check what constrains your particular street, then draw the scheme to Building Control standard.
The district median stood at £580,000 on last year's Land Registry returns, with OPDC regeneration reshaping the ground around it. Family space added by a well-designed rear extension or loft is worth appreciably more here than building it and drawing it cost.
Against a district median of £580,000 — the Land Registry recorded 492 NW10 sales in 2025 — our drawing fee is modest beside what the work adds to the Victorian and Edwardian terraces, inter-war semis and converted industrial buildings that make up the area. Brent's own statutory charge sits on top and is fixed nationally: £548 on a householder application, £610 on a full one. The drawings are quoted as a single fixed price, and we survey the property for free wherever it stands in NW10.
Across Willesden, Harlesden, Kensal Green, Willesden Green and the Park Royal fringe, instruction to submission runs about three to four weeks. The survey happens first, inside the opening week. Drawings and your revisions occupy the fortnight after it. Then validation, and Brent's statutory determination — eight weeks on a householder application. Officer queries are ours to handle through to the decision.
Willesden and the wider NW10 district sit overwhelmingly in Brent — 91.9% of the district's 2025 property sales were at Brent addresses — so Brent Council decides nearly everything from here, with Ealing taking the Park Royal edge. One local habit is worth knowing before you fix a date. Of the 5,822 applications Brent determined across its last three years of MHCLG returns, 1,819 carried an agreed extension of time: 31.2%, a little under the 34.5% recorded across London. An extension is agreed rather than imposed, and it stops the eight-week clock. Article 4 directions apply in the borough, and inside the designated areas — Kensal Green, Roundwood, Harlesden — external work becomes a full application accompanied by a Heritage Statement. Which route your particular address takes, we establish before quoting.
Almost always. Structural work following on from the survey — new openings, steel beams, loft floors, foundations — needs Building Regulations approval, which means Part A for structure, Part B for means of escape and Part L for insulation, lodged with Brent Building Control or with an approved inspector instead. NW10 is mostly terraces and semis, which puts a Party Wall notice on the critical path ahead of any steelwork. The Complete package covers the coordination of both.
In value terms, usually. The 2025 price-paid returns record 492 NW10 sales at a median of £580,000, and floor area added by a well-drawn extension or loft is generally worth more than building it. What proves expensive is the scheme nobody approved, or one that quietly misses a regulation. Drawings a case officer can validate, and an inspector's sign-off at the end, are how that gets avoided.
Planning history and precedent stop at the borough line, so the comparable approvals nearby may sit elsewhere. See all services in NW2 and NW6.

| Postcode | Area | Dominant stock | What it means for a measured building survey |
|---|---|---|---|
| NW10 | Willesden / Harlesden / Kensal Green | Modern apartments, post-war estates | NW10 does not belong to a single council. A survey in Willesden, Harlesden or Kensal Green may be validated by Brent or by Ealing depending on the street, and the policies map is what settles it. |
| NW10 | Harlesden | Victorian terraces | Harlesden is NW10 from end to end, with no boundary complication, so Brent Council determines every application arising there. |
| NW10 | Kensal Green | Victorian terraces | Kensal Green lies within NW10, and survey-led proposals from those streets are determined by Brent Council. |
| NW10 | Willesden | Victorian terraces, Edwardian terraces | Willesden itself is Brent territory, so applications from NW10 addresses in Willesden go to the borough. |
| NW10 | Neasden | 1930s semi-detached, post-war | Neasden falls inside NW10 at its northern end and answers to Brent Council for both survey and application work. |
| NW10 | Park Royal | Modern apartments, post-war estates | Park Royal is the exception here. Much of it falls inside the Old Oak and Park Royal Development Corporation's area, where OPDC rather than the borough acts as planning authority, and the balance sits with Ealing. Check the site before assuming Brent. |
| NW2 | Cricklewood / Neasden | Edwardian villas and terraces | Adjoining district to NW10. Surveying needs no consent here either — Brent has no say in it, and the survey is the same record whichever side of the line the property sits. |
| HA0 | Wembley / Sudbury | 1930s semi-detached, new-build | Adjoining district to NW10. Surveying needs no consent here either — Brent has no say in it, and the survey is the same record whichever side of the line the property sits. |
| HA9 | Wembley / Wembley Park | 1930s semi-detached, new-build | Adjoining district to NW10. Surveying needs no consent here either — Brent has no say in it, and the survey is the same record whichever side of the line the property sits. |
| W3 | Acton | Victorian and Edwardian terraces | Adjoining district to NW10. A survey is a record rather than an application, so nothing about it changes at the Ealing boundary. |
| W5 | Ealing | Edwardian villas, Victorian terraces | Adjoining district to NW10. A survey is a record rather than an application, so nothing about it changes at the Ealing boundary. |
| W7 | Hanwell | Edwardian villas, 1930s semi-detached | Adjoining district to NW10. A survey is a record rather than an application, so nothing about it changes at the Ealing boundary. |
Pitch, wall build-up and plot depth all shift over the course of a few NW10 streets, and each shift changes what a measured survey has to capture at that address.
NW10 (Willesden / Harlesden / Kensal Green) conservation designations: there are 22 across Brent Council, Harlesden, Sudbury Court, Queen's Park among them. Designation costs a NW10 (Willesden / Harlesden / Kensal Green) owner the permitted-development route: a measured building survey then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Kensal Green is the NW10 (Willesden / Harlesden / Kensal Green) designation that most often changes a measured building survey design.
What Article 4 removes near NW10 (Willesden / Harlesden / Kensal Green): Article 4 for HMO conversions in specific streets around Wembley and Harlesden. Before pricing a measured building survey we check whether the NW10 address is inside the mapped area, because Brent Council draws the NW10 (Willesden / Harlesden / Kensal Green) boundary street by street rather than across the whole of NW10 (Willesden / Harlesden / Kensal Green).
