Measured Building Surveys · DA15 Sidcup
Bexley protects the Lamorbey conservation area, with its parkland and older houses, alongside standard suburban householder control across the rest of DA15.
Bexley, covering Sidcup and Blackfen — the borough that approves more householder applications than any other in London, at 91.7%, and settles 97.9% of them inside eight weeks. It withdrew only 3.0% before decision. Bexley also withdrew only 3.0% of applications before decision, the lowest withdrawal rate of the 33 boroughs, and issued 882 lawful development certificates.

Sidcup DA15 — local contextIf your property sits elsewhere in the borough, the borough-wide page for measured building surveys in Bexley covers the same service across every ward.
A measured building survey captures your Sidcup property exactly — every wall, opening, level and boundary — as the accurate base for design and planning drawings. On DA15's older terraced and villa stock around Sidcup, Lamorbey, Blackfen fringe, Albany Park fringe, walls are rarely square, so a laser-measured survey prevents costly errors before Bexley Council ever sees the application.

Across Sidcup, Lamorbey, Blackfen fringe, Albany Park fringe in DA15, the dominant property is inter-war semis and detached houses around sidcup and lamorbey, with some edwardian and post-war infill. 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 Bexley Council judges each on design quality and neighbour impact. We survey the specific Sidcup property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the DA15 streetscape.
Housing stock in DA15: Inter-war semis and detached houses around Sidcup and Lamorbey, with some Edwardian and post-war infill.
Within the district: Sidcup, Lamorbey, Blackfen fringe, Albany Park fringe.
Streets we know in DA15: the Lamorbey streets, the roads around Sidcup station and the inter-war estates toward Blackfen. Each road has its own building line, boundary treatment and precedent that Bexley Council weighs when assessing a measured building survey scheme.
Conservation areas: Lamorbey, Sidcup (The Hollies fringe). Inside these, most external work needs full planning and a Heritage Statement.
Getting around DA15: Sidcup and Albany Park into London Bridge, Cannon Street and Charing Cross.
Property values: the Land Registry recorded 453 sales in DA15 across 2025, half of them above £457,000. The district's average, £499,798, runs higher than that midpoint because the largest sales pull it up; the median is the better guide.
Borough character: Outer south-east London suburban; very permissive planning environment; strong PD uptake for extensions and loft conversions.

Because DA15 is a settled family suburb of inter-war semis and detached houses around Sidcup and Lamorbey — ideal for rear, side and wrap-around extensions and loft conversions. Outside the Lamorbey conservation area, much runs on the Permitted Development route, confirmed with a Lawful Development Certificate.
Yes — the Lamorbey conservation area protects the older houses and the parkland setting, so external changes there need full planning with a Heritage Statement. We design sympathetically and handle the Bexley application where the conservation route applies.
Usually yes on the semis and detached houses outside the conservation area — a hip-to-gable plus rear dormer within the volume allowance, confirmed by a Lawful Development Certificate. We check the head height and any Lamorbey constraint, then draw for Building Control too.
With DA15 houses around £450,000-£725,000 and direct trains into London Bridge, a rear or loft extension adds family space worth above the build and drawing cost. DA15 offers strong commuter value.
Bexley Council charges its own statutory application fee (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 DA15 address.
For a DA15 project across Sidcup, Lamorbey, Blackfen fringe, Albany Park 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 Bexley Council (8 weeks for a householder application). We carry the Sidcup application through every officer query to the decision.
Sidcup (DA15) sits primarily in Bexley, so applications are decided by Bexley Council. Conservation areas within DA15 include Lamorbey, Sidcup (The Hollies fringe), 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 measured building survey in Sidcup — 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 Bexley Council Building Control or an approved inspector. On DA15'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. 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 DA15 homes.
Neighbouring authorities set their own policies, and the boundary rarely matches the postcode. Full service listings for DA5, DA6 and DA7.

Every DA15 postcode district we draw in, the stock that dominates it and the authority that validates a measured building survey there. DA15 fees below are the statutory England rates for 2026, not measured building survey estimates.
| Postcode | Area | Dominant stock | What it means for a measured building survey |
|---|---|---|---|
| DA15 | Sidcup | 1930s semi-detached, Edwardian villas | Not determined by anyone. A survey is measurement, taken for the owner and used by whoever draws next. Sidcup's DA15 houses are mainly 1930s, built quickly in long runs, and the roofs are where the differences show up once dormers and hip-to-gable work have been added. |
| DA1 | Crayford / Dartford fringe | Victorian terraces, 1930s semi-detached | Adjoining district to DA15. Surveying needs no consent here either — Bexley has no say in it, and the survey is the same record whichever side of the line the property sits. |
| DA5 | Old Bexley | Georgian villas, Victorian cottages | Adjoining district to DA15. Surveying needs no consent here either — Bexley has no say in it, and the survey is the same record whichever side of the line the property sits. |
| DA6 | Bexleyheath | 1930s semi-detached | Adjoining district to DA15. Surveying needs no consent here either — Bexley has no say in it, and the survey is the same record whichever side of the line the property sits. |
| DA7 | Bexleyheath / Barnehurst | 1930s semi-detached | Adjoining district to DA15. Surveying needs no consent here either — Bexley has no say in it, and the survey is the same record whichever side of the line the property sits. |
Roof pitch, wall build-up and plot depth change every few DA15 streets, and each one changes what a measured building survey can achieve at that address.
How designation changes a DA15 (Sidcup) measured building survey: Bexley Council maintains 16 conservation areas, including Welling, Bexley Village, Old Bexley. Inside any of them a DA15 (Sidcup) 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. Crayford sets the tone for DA15 (Sidcup) casework.
Article 4 and your DA15 (Sidcup) measured building survey: Bexley Council has made no borough-wide direction, so permitted development for a measured building survey in DA15 (Sidcup) generally survives outside DA15 (Sidcup) conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a DA15 owner records that a measured building survey was lawful.
The building fabric around DA15 (Sidcup): 1930s semi-detached dominates; Victorian cottages in Bexley Village and Crayford; post-war estates in Thamesmead and Erith. Outer south-east London suburban; very permissive planning environment; strong PD uptake for extensions and loft conversions. A measured building survey in DA15 (Sidcup) is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Bexley Council.
