A measured building survey captures your Carshalton property exactly — every wall, opening, level and boundary — as the accurate base for design and planning drawings. On SM5's older terraced and villa stock around Carshalton, Carshalton Beeches, The Wrythe, Hackbridge fringe, walls are rarely square, so a laser-measured survey prevents costly errors before Sutton Council ever sees the application.
Fixed-fee measured surveys across Carshalton from £540 — floor plans, elevations and sections to ±3mm accuracy. Leica Disto laser + BLK360 point-cloud scanning, AutoCAD and Revit deliverables, MCIAT chartered.
Across Carshalton, Carshalton Beeches, The Wrythe, Hackbridge fringe in SM5, the dominant property is victorian and edwardian houses around carshalton village, with inter-war semis and larger plots near the ponds and carshalton park. 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 Sutton Council judges each on design quality and neighbour impact. We survey the specific Carshalton property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SM5 streetscape.

Listed, conservation or complex sites.
Yes. The Victorian and Edwardian houses and inter-war semis around Carshalton suit side-return, rear and loft extensions.

The Carshalton Village and Carshalton Park conservation areas protect the historic streets around the spring-fed ponds and The Square, so external changes there are carefully assessed. Properties near the water also need a flood-risk check. We design sympathetically and handle the Sutton application.
Usually yes on houses outside the conservation areas — a hip-to-gable or rear dormer within the volume allowance, confirmed by a Lawful Development Certificate. Inside the Village or Park designations, roof changes need full planning. We confirm which applies to your SM5 road.
With SM5 houses around £550,000-£900,000 and direct Thameslink trains to the City, a rear or loft extension adds family space worth above the build and drawing cost. Carshalton's pond-side village setting is highly sought after, and our fixed fee keeps the cost predictable.
Our fixed fee for measured building survey in Carshalton starts at £540 — no hourly billing. With Carshalton property at around £325,000 for a flat and £550,000-£900,000 for a house, the professional drawing fee is a small fraction of the value the work adds to SM5's victorian and edwardian houses around carshalton village. Sutton Council charges its own statutory application fee on top (currently £258 for a householder planning application, £578 for a full application).

We confirm the planning route for your exact address before quoting.
Almost always. Any structural work behind measured building survey in Carshalton — 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 Sutton Council Building Control or an approved inspector. On SM5'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 Carshalton (SM5) property at around £325,000 for a flat and £550,000-£900,000 for a house, a well-designed extension or loft typically returns more than it costs in added floor area and sale value, while our fixed drawing fee from £540 keeps the professional cost predictable. 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 SM5 homes.

Every SM5 postcode district we draw in, the stock that dominates it and the authority that validates a measured building survey there. SM5 fees below are the statutory England rates for 2026, not measured building survey estimates.

| SM1 | Sutton | Edwardian terraces, 1930s semi-detached | Adjoining district to SM5, also inside Sutton for measured building survey purposes. |
