Measured Building Surveys · SE26 Sydenham
Lewisham controls the Sydenham Hill and Westwood Park conservation areas; the hillside villas and terraces are a strong, well-priced extension market.
If your property sits elsewhere in the borough, the borough-wide page for measured building surveys in Lewisham covers the same service across every ward.
A measured building survey captures your Sydenham property exactly — every wall, opening, level and boundary — as the accurate base for design and planning drawings. On SE26's older terraced and villa stock around Sydenham, Upper Sydenham, Lower Sydenham, Crystal Palace fringe, walls are rarely square, so a laser-measured survey prevents costly errors before Lewisham Council ever sees the application.

Across Sydenham, Upper Sydenham, Lower Sydenham, Crystal Palace fringe in SE26, the dominant property is victorian and edwardian terraces and villas on the sydenham slopes, with inter-war semis and post-war estates toward lower sydenham. 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 Lewisham Council judges each on design quality and neighbour impact. We survey the specific Sydenham property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SE26 streetscape.
Housing stock in SE26: Victorian and Edwardian terraces and villas on the Sydenham slopes, with inter-war semis and post-war estates toward Lower Sydenham.
Within the district: Sydenham, Upper Sydenham, Lower Sydenham, Crystal Palace fringe.

Conservation areas: Sydenham Hill / Kirkdale, Westwood Park, Sydenham Park. Inside these, most external work needs full planning and a Heritage Statement.

BLK360 scan delivers a full 3D point cloud — ideal for Sydenham period properties, listed buildings or complex geometry.
DWG, RVT, PDF and IFC exports — compatible with your architect, structural engineer or contractor.
RICS-compliant accuracy report — ±3mm point-to-point, ±5mm absolute. Sign-off for council, party wall surveyor or insurer.
Single planning or building-regs submission.
Planning + building regs + structural.
Listed, conservation or complex sites.
Yes. The Victorian and Edwardian terraces and villas around Kirkdale and Wells Park Road suit side-return, rear and loft extensions, much of it within Permitted Development outside the conservation areas, confirmed with a Lawful Development Certificate. We confirm the route and draw to Lewisham's checklist.
Yes. The Sydenham Hill, Westwood Park and Sydenham Park conservation areas protect the large hillside villas, so external changes there need full planning with a Heritage Statement. We design sympathetically to the period detailing and submit to Lewisham, carrying the application through officer queries.
Usually yes outside the conservation areas — a rear dormer or hip-to-gable within the volume allowance, confirmed by a Lawful Development Certificate. The steep Sydenham slopes sometimes affect roof design and overlooking, which we assess. Inside the designations, roof changes need full planning.
With SE26 houses around £600,000-£900,000, Sydenham offers strong south-London value, and a side-return or loft adds family space worth comfortably above the build and drawing cost. The Overground link to Shoreditch and Highbury keeps demand steady.
Lewisham 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 SE26 address.
For a SE26 project across Sydenham, Upper Sydenham, Lower Sydenham, Crystal Palace 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 Lewisham Council (8 weeks for a householder application). We carry the Sydenham application through every officer query to the decision.
Sydenham (SE26) sits primarily in Lewisham, so applications are decided by Lewisham Council. Conservation areas within SE26 include Sydenham Hill / Kirkdale, Westwood Park, Sydenham Park, 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 Sydenham — 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 Lewisham Council Building Control or an approved inspector. On SE26'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 SE26 homes.
Local policy varies more between adjoining boroughs than most owners expect. Full service detail for SE3, SE4, SE6, SE12, SE13 and SE23.
Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every SE26 postcode district we draw in, the stock that dominates it and the authority that validates a measured building survey there. SE26 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 |
|---|---|---|---|
| SE26 | Sydenham | Victorian villas, Edwardian terraces | A measured building survey in Sydenham may land with Lewisham Council or Bromley Council — SE26 crosses the boundary, and the SE26 policies map decides it street by street. |
| SE4 | Brockley | Victorian and Edwardian terraces | Adjoining district to SE26. Surveying needs no consent here either — Lewisham has no say in it, and the survey is the same record whichever side of the line the property sits. |
| SE6 | Catford / Bellingham | 1930s semi-detached, post-war flats | Adjoining district to SE26. Surveying needs no consent here either — Lewisham has no say in it, and the survey is the same record whichever side of the line the property sits. |
| SE8 | Deptford | Georgian terraces, post-war estates, new-build | Adjoining district to SE26. Surveying needs no consent here either — Lewisham has no say in it, and the survey is the same record whichever side of the line the property sits. |
| SE12 | Lee / Grove Park | mixed stock | Adjoining district to SE26. Surveying needs no consent here either — Lewisham has no say in it, and the survey is the same record whichever side of the line the property sits. |
| SE20 | Anerley / Penge | Victorian and Edwardian terraces | Adjoining district to SE26. A survey is a record rather than an application, so nothing about it changes at the Bromley boundary. |
| BR1 | Bromley / Bickley | Victorian terraces, Edwardian villas, post-war flats | Adjoining district to SE26. A survey is a record rather than an application, so nothing about it changes at the Bromley boundary. |
| BR2 | Hayes / Keston | Victorian terraces, Edwardian villas, post-war flats | Adjoining district to SE26. A survey is a record rather than an application, so nothing about it changes at the Bromley boundary. |
| BR3 | Beckenham | Edwardian villas, 1930s semi-detached | Adjoining district to SE26. A survey is a record rather than an application, so nothing about it changes at the Bromley boundary. |
Roof pitch, wall build-up and plot depth change every few SE26 streets, and each one changes what a measured building survey can achieve at that address.
