Building Regulations Drawings · 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.
The borough-level guide to building regulations drawings in Bromley sets out how the same work is handled across the rest of the authority.
Building regulations drawings for a Hayes project turn the design into a construction-ready set — Part A structure, Part B fire, Part L thermal, Part M access — for Bromley Council Building Control or an approved inspector. On BR2's inter-war and edwardian semis and detached houses, the recurring details are steel beams over knocked-through ground floors, loft floor build-ups, and insulation upgrades to solid period walls around Hayes, Bromley Common, Keston, Bickley fringe.
A construction-ready drawing package compliant with every Approved Document — Part A structure, Part B fire, Part L thermal, Part M accessibility — submitted to LABC or your approved inspector with structural calculations coordinated.
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 building regulations drawings 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.

Conservation areas: Hayes Village, Keston. Inside these, most external work needs full planning and a Heritage Statement.
Getting around BR2: Hayes (the Hayes line terminus) into Charing Cross and Cannon Street.
Property values: around £325,000 for a flat and £600,000-£1.1m for a house — a useful gauge of the build value an extension or loft adds in BR2.

Because BR2 is a leafy family market of inter-war and Edwardian semis and detached houses on generous plots around Hayes and Keston — ideal for substantial rear, side and wrap-around extensions and loft conversions. Outside the conservation areas and green belt, much runs on the Permitted Development route, confirmed with a Lawful Development Certificate.
Properties on the edge of Hayes Common, Keston Common or the metropolitan green belt face tighter limits on extending the footprint, so we check whether your plot is washed over by green belt before designing. Within the built-up area, normal householder and PD rules apply, which we confirm at survey.
Usually yes on the semis and detached houses outside the conservation areas — a hip-to-gable plus rear dormer within the volume allowance, confirmed by a Lawful Development Certificate. The generous BR2 roofs often give good head height. We draw the scheme for Building Control too.
With BR2 houses around £600,000-£1.1m and a direct line to Charing Cross, a rear or loft extension adds family space worth above the build and drawing cost. BR2's green, village-edge setting is highly sought after.
With Hayes property at around £325,000 for a flat and £600,000-£1.1m for a house, the professional drawing fee is a small fraction of the value the work adds to BR2's inter-war and edwardian semis and detached houses. Bromley Council charges its own statutory application fee on top (currently £548 for a householder planning application, £610 for a full application). We quote the drawings as one fixed price and the free site survey covers every BR2 address.
For a BR2 project across Hayes, Bromley Common, Keston, Bickley fringe, expect roughly 3–4 weeks from instruction to submission: week 1 the measured survey, weeks 2–3 the drawings and your revisions, then validation and the statutory determination by Bromley Council (8 weeks for a householder application). We carry the Hayes application through every officer query to the decision.
Hayes (BR2) sits primarily in Bromley, so applications are decided by Bromley Council. Conservation areas within BR2 include Hayes Village, Keston, where full planning and a Heritage Statement are required. We confirm the planning route for your exact address before quoting.
Almost always. Any structural work behind building regulations drawings 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, yes. With Hayes (BR2) property at around £325,000 for a flat and £600,000-£1.1m for a house, a well-designed extension or loft typically returns more than it costs in added floor area and sale value. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on BR2 homes.
Householders often approach us after a neighbour used a different council. Our full range is set out for SE9, SE12, SE20, SE26, BR1, BR3, BR6 and BR7.

Every BR2 postcode district we draw in, the stock that dominates it and the authority that validates a building regulations package there. BR2 fees below are the statutory England rates for 2026, not building regulations package estimates.
| Postcode | Area | Dominant stock | What it means for a building regulations package |
|---|---|---|---|
| BR2 | Hayes / Keston | Victorian terraces, Edwardian villas, post-war flats | BR2 covers Hayes / Keston only; Bromley Council handles the building regulations package. |
| BR2 | Bromley | Victorian terraces, Edwardian villas, post-war flats | A BR2 address in Bromley can route building control through Bromley Council or through an approved inspector. Both discharge the same duty; the fee and the inspection timetable are what differ. |
| BR2 | Keston | Edwardian villas, 1930s semi-detached | Keston sits inside BR2. The Building Regulations check can be bought from Bromley Council building control or from a private approved inspector — the owner chooses, and the choice is not tied to the borough boundary. |
| SE20 | Anerley / Penge | Victorian and Edwardian terraces | Adjoining district to BR2. The Building Regulations are national; only the choice of inspector is local, and even that is not fixed by Bromley. |
| BR1 | Bromley / Bickley | Victorian terraces, Edwardian villas, post-war flats | Adjoining district to BR2. The Building Regulations are national; only the choice of inspector is local, and even that is not fixed by Bromley. |
| BR3 | Beckenham | Edwardian villas, 1930s semi-detached | Adjoining district to BR2. The Building Regulations are national; only the choice of inspector is local, and even that is not fixed by Bromley. |
Roof pitch, wall build-up and plot depth change every few BR2 streets, and each one changes what a building regulations package can achieve at that address.
BR2 (Hayes / Keston) conservation designations: there are 48 across Bromley Council, Bromley Town, Chislehurst, Beckenham among them. Designation costs a BR2 (Hayes / Keston) owner the permitted-development route: a building regulations package then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Beckenham is the BR2 (Hayes / Keston) designation that most often changes a building regulations package design.
No blanket Article 4 over BR2 (Hayes / Keston): Bromley Council has not withdrawn permitted development across BR2 (Hayes / Keston), so a building regulations package 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.
What BR2 (Hayes / Keston) is built from: 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. That mix decides the building regulations package route in BR2 (Hayes / Keston) more than the postcode does, and it is what a Bromley Council case officer reads first. A householder application costs £548 paid to Bromley Council direct, with 8 weeks to a decision once validated.
