Measured Building Surveys · BR2 Hayes
Bromley protects the Hayes Village and Keston conservation areas and the surrounding metropolitan green belt and commons, alongside standard householder control across BR2.
Working somewhere else in the borough rather than only in this district? The whole-authority view sits under measured building surveys in Bromley.
A measured building survey captures the Hayes property precisely as it was built, walls and openings and levels and boundaries alike, and becomes the base that design and planning drawings are built on top of. On the older houses through Hayes, Bromley Common, Keston and the Bickley fringe, walls are rarely parallel, and a laser survey catches that long before Bromley Council opens the application.
Laser distance measurement and scanning on site, AutoCAD and Revit deliverables afterwards, and all of it under an MCIAT chartered technologist who was at the property in person.
Across Hayes, Bromley Common, Keston, Bickley fringe in BR2, the dominant property is inter-war and edwardian semis and detached houses around hayes and bromley common, with larger plots toward keston and the green belt. 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 Bromley Council judges each on design quality and neighbour impact. We survey the specific Hayes property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the BR2 streetscape.
Housing stock in BR2: inter-war and Edwardian semis and detached houses around Hayes and Bromley Common, with plots widening out towards Keston and the green belt. Across the borough, 143,430 dwellings break down as 25.7% built during the 1930s and 12.1% before 1900, on VOA figures dated 31 March 2025.
Within the district: Hayes, Bromley Common, Keston, Bickley fringe.
Streets we know in BR2: the Hayes village streets, the roads around Hayes Common and the larger plots toward Keston. Each road has its own building line, boundary treatment and precedent that Bromley Council weighs when assessing a measured building survey scheme.
Conservation areas: Hayes Village and Keston are the designations covering parts of this district. Inside either, an external alteration means a full application with heritage justification rather than a certificate.
Getting around BR2: Hayes station is the terminus of its own branch line, running direct into Charing Cross and Cannon Street without a change anywhere.
Property values: the median BR2 sale in 2025 came in at £553,000 across 667 registered transactions, a little above the £525,000 borough median. Hold that number in mind when judging what an extension is likely to add. Source: HM Land Registry Price Paid Data
What else lands on the same desk: householder work is only part of the caseload. Bromley decided 1,568 applications on minor schemes in the three financial years closing March 2026, and BR2 sends its share of them, mostly flat conversions around Hayes and Bromley Common where an accurate set of existing plans is the difference between validation and a hold.

Borough character: no London borough covers more ground than this one — roughly 150 square kilometres, under half of it built up. Green belt and the conservation areas around the town centres therefore do more work here than density does; away from those, the council is comparatively permissive.
A chartered technologist attends the Hayes address with laser measuring equipment and a BLK360 scanner. Most two and three bedroom houses are covered in around ninety minutes on site.
Sheets are produced in AutoCAD or Revit, 1:100 for general arrangement and 1:50 where a builder has to work straight off the print, to a three-millimetre tolerance, with every fitting, opening and service run marked in its place.
Every elevation, plus cross-sections through the house, is drawn as part of the standard package — the council's validation list, a party wall award and a steel design all ask for the vertical picture, not just the plan.
Scanning yields a complete point cloud, and the older houses towards Hayes Village and Keston are exactly where that earns its cost, where nothing is square and the original drawings, if they survive at all, were optimistic.
Issued formats are DWG, RVT, PDF and IFC together, letting an engineer or a contractor work from the native model rather than scaling measurements off a printed sheet.
An accuracy report on RICS terms travels with the drawings: three millimetres point to point, five across the whole building. Before anyone relies on the geometry — the council's Building Control team, an insurer, the party wall surveyor — that is the document they ask for.

Because this is a family market of inter-war and Edwardian semis and detached houses on generous plots, which suits substantial rear, side and wrap-around extensions and full loft conversions. Outside the conservation areas and clear of the green belt, a good deal of that runs on permitted development and needs only a certificate to prove it.
Plots along the edge of Hayes Common, Keston Common or the metropolitan green belt carry far tighter limits on any increase in footprint, and that is a live issue in this borough, where built-up land accounts for just 49.3% of the total. We check whether green belt washes over your plot before designing, because inside it the test becomes whether the addition is disproportionate, not whether it fits an allowance.
Usually, on the semis and detached houses outside the designated areas: hip-to-gable plus a rear dormer, held within the volume allowance, then evidenced by a Lawful Development Certificate. Bromley recorded 1,675 certificates in three years, so it is a well-worn route here, and roofs in this district are generous enough that head height is rarely the binding constraint. We draw it for Building Control as well as for the certificate.
With the district median at £553,000 last year and the Hayes branch running into Charing Cross and Cannon Street, a rear extension or a loft delivers family space at a price this local market carries comfortably. Source: HM Land Registry Price Paid Data
Against a district median of £553,000 last year the drawing fee is small, and it is what stands between the rest of the budget and a refusal in a borough that turns down one householder application in five. Bromley Council's statutory charge sits on top: £548 is the householder charge, £610 the charge on a full application. Our figure is fixed when we quote and covers the site visit at any address in the district. Source: HM Land Registry Price Paid Data
Across Hayes, Bromley Common, Keston and the Bickley fringe, a three to four week run from instruction to submission is realistic: the measured survey, then drawings and your changes, then validation and the eight-week determination period Bromley Council works to on a householder application. We carry it through the officer's queries as far as the decision notice.
Every BR2 address lies inside Bromley, so there is no ambiguity about the authority: Bromley Council decides all of it. Nor has this authority made any borough-wide Article 4 Direction over householder permitted development. What changes the route is designation — Hayes Village, Keston — or green belt, and we confirm which of those touches your plot before quoting.
Almost always. Any structural work behind measured building survey in Hayes — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Bromley Council Building Control or an approved inspector. On BR2's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms it does, and this is a district where the arithmetic is comfortable: 667 BR2 properties changed hands during 2025 at a median of £553,000 on the Land Registry price-paid returns, against £525,000 across Bromley as a whole, and borough prices rose 5.0% on the year while inner London medians fell. The counterweight is the decision itself. Bromley refuses householder applications more often than London does — 950 refusals out of 4,706 decisions in three years, one in five, where the 33 boroughs together refuse 17% — so the value only materialises on a scheme the council will actually pass.

Which districts we draw in, the construction that dominates each, and the authority validating a survey at a given address. Fees listed below are England's statutory rates for 2026 and go to the council, not to us.
| Postcode | Area | Dominant stock | What it means for a measured building survey |
|---|---|---|---|
| BR2 | Hayes / Keston | Victorian terraces, Edwardian villas, post-war flats | BR2 covers Hayes and Keston only, all of it Bromley ground, and case officers read each proposal against the BR2 conservation-area map. |
| BR2 | Bromley | Victorian terraces, Edwardian villas, post-war flats | Bromley itself falls inside BR2. An application from those streets does go to Bromley Council, but the survey behind it does not: no authority validates or approves a set of existing drawings. What shapes the BR2 job is plot size, and how far back from the road the houses sit. |
| BR2 | Keston | Edwardian villas, 1930s semi-detached | Keston sits inside BR2 as well, so Bromley Council decides proposals there, with the green belt boundary an additional consideration on many plots. |
| SE20 | Anerley / Penge | Victorian and Edwardian terraces | Adjoining district to BR2. Surveying needs no consent here either — Bromley has no say in it, and the survey is the same record whichever side of the line the property sits. |
| BR1 | Bromley / Bickley | Victorian terraces, Edwardian villas, post-war flats | Adjoining district to BR2. Surveying needs no consent here either — Bromley has no say in it, and the survey is the same record whichever side of the line the property sits. |
| BR3 | Beckenham | Edwardian villas, 1930s semi-detached | Adjoining district to BR2. Surveying needs no consent here either — Bromley has no say in it, and the survey is the same record whichever side of the line the property sits. |
Roof pitch varies here within a few streets, so does wall build-up, so does plot depth, and every one of those variations changes what a survey can establish about the house.
How designation changes a BR2 (Hayes / Keston) measured building survey: Bromley Council maintains 48 conservation areas, including Beckenham, Keston, Bickley. Inside any of them a BR2 (Hayes / Keston) measured building survey cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Chislehurst sets the tone for BR2 (Hayes / Keston) casework.
No blanket Article 4 over BR2 (Hayes / Keston): Bromley Council has not withdrawn permitted development across BR2 (Hayes / Keston), so a measured building survey outside a BR2 (Hayes / Keston) conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a BR2 owner wants on file.
BR2 (Hayes / Keston) housing stock: Large 1930s detached and semi-detached in Chislehurst and Bickley; Edwardian in Beckenham; Victorian in Bromley town; Metropolitan Green Belt covers significant rural-fringe land. Largest London borough by area; substantial Green Belt; conservation areas in most town centres; generally permissive elsewhere. Read that before choosing a measured building survey route in BR2 (Hayes / Keston) — construction, not postcode, sets what is achievable. Bromley Council charges £548 for a householder application and has 8 weeks to determine it.
