Measured Building Surveys in Lewisham

Which Lewisham postcodes does this measured building survey service cover?

A survey is not validated by anybody — it is the drawing everything else is built on — but the authority that will eventually read it decides how much of it has to be right. The table below gives each Lewisham postcode district, the stock that dominates it, and the council that determines an application from that address, which along the SE4, SE23 and SE3 edges is not always Lewisham. Any fees quoted are the statutory England application rates for 2026, not survey prices.

How does a measured building survey differ street by street across Lewisham?

Just over a quarter of Lewisham — 27.7% of 133,880 homes — predates 1900 (VOA council tax stock by build period at 31 March 2025, retrieved 1 September 2026), and Victorian buildings are where assumed dimensions go wrong. Solid nine-inch walls are not 100mm plus a cavity. Back additions were rebuilt, raised and re-roofed over a century and rarely match the drawings anyone holds. Floor levels step between the main house and the return. The neighbourhoods below are grouped by which of those problems the survey has to resolve before a scheme can be drawn against them.

• Sydenham (SE26) — measured building survey work in Sydenham means victorian villas, edwardian terraces. Sydenham is Victorian villas, Edwardian terraces. Victorian terraces here have settled and bowed throughout SE26. Lewisham Council decides the Sydenham application, and Sydenham Wells Park anchors the Sydenham location plan.
• Brockley (SE4) — measured building survey work in Brockley means victorian and edwardian terraces. Brockley is Victorian and Edwardian terraces. Victorian terraces here have settled and bowed throughout SE4. Lewisham Council decides the Brockley application, and Brockley station anchors the Brockley location plan.
• Forest Hill (SE23) — a measured building survey in Forest Hill starts from victorian villas, edwardian terraces, and Forest Hill reads as Victorian villas, Edwardian terraces. Victorian terraces here have settled and bowed in SE23. Lewisham Council assesses Forest Hill measured building surveys against its own Forest Hill character guidance, and the location plan we draw for Forest Hill references Horniman Museum.
• Honor Oak (SE23) — measured building survey work in Honor Oak means victorian villas, edwardian terraces. Honor Oak is Victorian villas on the hill. Victorian terraces here have settled and bowed throughout SE23. Lewisham Council decides the Honor Oak application, and One Tree Hill anchors the Honor Oak location plan.
• Lewisham (SE13) — measured building survey work in Lewisham means victorian terraces, post-war flats. Lewisham is Victorian terraces, post-war centre. Victorian terraces here have settled and bowed throughout SE13. Lewisham Council decides the Lewisham application, and Lewisham station anchors the Lewisham location plan.
• Blackheath (SE3) — measured building survey work in Blackheath means georgian villas, victorian terraces. Blackheath is Georgian and Victorian villas around the heath. Georgian houses here are rarely square throughout SE3. Lewisham Council decides the Blackheath application, and Blackheath anchors the Blackheath location plan.
• Catford (SE6) — a measured building survey in Catford starts from 1930s semi-detached, post-war flats, and Catford reads as 1930s semi-detached, post-war centre. 1930s semis here are dimensionally consistent in SE6. Lewisham Council assesses Catford measured building surveys against its own Catford character guidance, and the location plan we draw for Catford references Catford Cat.

What local planning policy applies to a measured building survey in Lewisham?

The number that makes the survey worth buying here: Lewisham refused 135 of the 305 larger rear extensions notified to it under the prior approval procedure in the twelve quarters to March 2026 — 44.3%, the third highest refusal share of the twenty-seven boroughs the national return supports a rate for, against 24.9% across London (MHCLG planning statistics, retrieved 1 September 2026). The prior approval test is almost entirely dimensional: depth from the original rear wall, height at the eaves, height overall, and where the original wall actually was on a house that has already been extended once. Those are survey questions, not design questions, and a scheme measured from an estate agent's floor plan is the usual way of getting one of them wrong.

The contrast with full applications: on everything decided the ordinary way, Lewisham is one of the more accommodating London boroughs. It granted 86.3% of 2,037 householder applications, decided 95.3% of them inside eight weeks, and granted 94 of 98 listed building consents to alter or extend — 95.9%, third highest of the boroughs whose caseload supports a rate. So a refused notification is rarely the end of a project here. It usually means the scheme belongs in a £548 householder application rather than a £249 notification, and a survey accurate enough to prove the dimensions is what lets you make that choice deliberately rather than after a refusal.

Where designation changes the brief: the national register lists 30 Lewisham conservation areas covering about 705 hectares (planning.data.gov.uk, retrieved 1 September 2026) — Blackheath, Brockley, Deptford High Street, Forest Hill and Hither Green among them. Inside one, the drawing set grows: a streetscene elevation showing the neighbours either side, and enough detail of window reveals, string courses and brick coursing for a heritage statement to describe what is being kept. That is a survey scope decision, made before the site visit rather than after. Outside the designations Lewisham has no borough-wide Article 4 direction, and 1,221 lawful development certificates were recorded over the same period — a count of applications, since the national return holds no granted-or-refused split for certificates in any English authority.

Who decides a measured building survey on the edge of Lewisham?

• Greenwich — the Blackheath boundary is the awkward one. A single heath is divided between two councils, and houses of the same date and detail on opposite sides are assessed by different conservation teams against different appraisals. The survey is identical either way; the drawing set it feeds is not.
• Southwark — runs along the north-western edge through Peckham, New Cross and Nunhead, cutting through continuous Victorian terraces rather than following a natural feature. Southwark is markedly more generous on householder applications than Lewisham is on notifications, so on this edge the route matters more than the address.
• Bromley — the southern edge past Bellingham and Downham, where the stock turns interwar and detached and the designated share rises sharply. Bromley holds 69 conservation areas in the national register against Lewisham's 30 (retrieved 1 September 2026), which is worth checking before assuming permitted development survives.
• Tower Hamlets — touched only across the river at Deptford and the Isle of Dogs, so it rarely divides a street. It matters as a contrast in stock: mostly flats north of the water, where Part 1 permitted development does not apply at all, against Lewisham's houses, where it usually does.
