Measured Building Surveys · SW18 Wandsworth
Wandsworth's borough-wide Article 4 removes HMO permitted-development rights. SW18's dense Victorian terraces in Earlsfield and the Tonsleys are classic side-return and loft territory and mostly outside conservation areas, while the larger villas around Wandsworth Common often fall inside the Wandsworth Common or Magdalen Park conservation areas.

A measured building survey captures your Wandsworth property exactly — every wall, opening, level and boundary — as the accurate base for design and planning drawings. On SW18's older terraced and villa stock around Wandsworth Town, Earlsfield, Southfields, The Tonsleys, Wandsworth Common, walls are rarely square, so a laser-measured survey prevents costly errors before Wandsworth Council ever sees the application.

Across Wandsworth Town, Earlsfield, Southfields, The Tonsleys, Wandsworth Common in SW18, the dominant property is victorian terraced houses across earlsfield and the 'tonsleys', edwardian villas around wandsworth common, and riverside new-build flats along the wandle delta at wandsworth town. 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 Wandsworth Council judges each on design quality and neighbour impact. We survey the specific Wandsworth property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SW18 streetscape.

Listed, conservation or complex sites.
Mostly yes. The grid of two-storey Victorian terraces across Earlsfield and the Tonsleys in SW18 is well suited to single-storey rear and side-return extensions under Permitted Development, decided by Wandsworth Council. The borough-wide Article 4 only affects HMO conversions, not standard householder extensions. We confirm your street is outside the Wandsworth Common and Magdalen Park conservation areas before relying on PD.
Yes — the main ones are Wandsworth Common, Magdalen Park and Tonsley. The villa streets nearest the common are the most likely to be covered, while the bulk of the Earlsfield and Southfields terraced grid sits outside. Inside these conservation areas, loft dormers, rendering and replacement windows need full planning. We map your exact address against the Wandsworth conservation layer first.
The larger semi-detached and detached Edwardian villas around Wandsworth Common often take a hip-to-gable conversion combined with a rear dormer, giving a full extra floor with two bedrooms. Smaller Earlsfield terraces usually take a rear or L-shaped dormer. Conservation-area villas need full planning and a sensitive design that keeps the front and side roof slopes legible from the street.
With Wandsworth property at approx £700k, £1.5m for houses, £850k for flats (Land Registry, 2024), the professional drawing fee is a small fraction of the value the work adds to SW18's victorian terraced houses across earlsfield and the. Wandsworth 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 SW18 address.
For a SW18 project across Wandsworth Town, Earlsfield, Southfields, The Tonsleys, Wandsworth Common, 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 Wandsworth Council (8 weeks for a householder application). We carry the Wandsworth application through every officer query to the decision.

Almost always. Any structural work behind measured building survey in Wandsworth — 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 Wandsworth Council Building Control or an approved inspector. On SW18'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 Wandsworth (SW18) property at approx £700k, £1.5m for houses, £850k for flats (Land Registry, 2024), 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 SW18 homes.

Every SW18 postcode district we draw in, the stock that dominates it and the authority that validates a measured building survey there. SW18 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 |
|---|---|---|---|
| SW18 | Wandsworth / Earlsfield / Southfields | Victorian villas and terraces | Wandsworth / Earlsfield / Southfields sits inside SW18. A measured survey needs no permission from Wandsworth Council or anyone else — it is the dimensioned record of what is already there. |
| SW18 | Wandsworth Common | Victorian villas and terraces | Wandsworth Common sits inside SW18. A survey is a record, not an application, so nothing is granted or refused at this stage; its accuracy is what decides whether the drawings built on it survive scrutiny. |
| SW18 | Earlsfield | Victorian terraces | No consent is required to survey a SW18 property in Earlsfield. The survey comes first so that whatever Wandsworth Council is later asked to decide rests on measured fact rather than an assumption about the existing building. |
| SW18 | Southfields | 1930s semi-detached, Edwardian terraces | Southfields sits inside SW18. A measured survey needs no permission from anyone; it is the dimensioned record of what is already there, and the base any later SW18 application is drawn on. |
| SW18 | Tonsleys | Victorian terraces | Tonsleys sits inside SW18. A measured survey needs no permission from anyone; it is the dimensioned record of what is already there, and the base any later SW18 application is drawn on. |
| SW11 | Battersea / Clapham Junction | Victorian terraces, mansion blocks | Adjoining district to SW18. Surveying needs no consent here either — Wandsworth has no say in it, and the survey is the same record whichever side of the line the property sits. |
