Planning Drawings · SM5 Carshalton
Sutton protects the Carshalton Village and Carshalton Park conservation areas, built around the historic ponds and spring-fed water features, alongside standard householder control elsewhere in SM5.
If your property sits elsewhere in the borough, the borough-wide page for planning drawings in Sutton covers the same service across every ward.
Planning drawings for Carshalton start by establishing whether your scheme is Permitted Development, needs a Lawful Development Certificate, or full planning from Sutton Council. On SM5's victorian and edwardian houses around carshalton village, the recurring questions are roof additions, rear and side-return extensions, and alterations within Carshalton Village, Carshalton Park, The Square (Carshalton). We draw existing and proposed plans, elevations and a site location plan to the council's validation checklist for Carshalton, Carshalton Beeches, The Wrythe, Hackbridge fringe.
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 planning permission drawings 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. Within the Carshalton Village or Carshalton Park conservation areas changes need full planning with a Heritage Statement; outside them, much runs on the Permitted Development route, confirmed with a Lawful Development Certificate.
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.

We carry the Carshalton application through every officer query to the decision.
Carshalton (SM5) sits primarily in Sutton, so applications are decided by Sutton Council. Conservation areas within SM5 include Carshalton Village, Carshalton Park, The Square (Carshalton), 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 planning permission drawings 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. 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.
Extensions on a boundary plot can involve two authorities. Everything we draw and submit is listed for SM1, SM2 and SM3.
Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every SM5 postcode district we draw in, the stock that dominates it and the authority that validates a planning drawing set there. SM5 fees below are the statutory England rates for 2026, not planning drawing set estimates.
| Postcode | Area | Dominant stock | What it means for a planning drawing set |
|---|---|---|---|
| SM5 | Carshalton | Victorian terraces, Georgian villas | Carshalton sits wholly inside SM5, so Sutton Council validates every planning drawing set submitted from an SM5 address. |
| KT4 | Worcester Park | 1930s semi-detached | Adjoining district to SM5, also inside Sutton for planning drawing set purposes. |
| SM1 | Sutton | Edwardian terraces, 1930s semi-detached | Adjoining district to SM5, also inside Sutton for planning drawing set purposes. |
| SM2 | Sutton / Belmont | Georgian villas, 1930s semi-detached | Adjoining district to SM5, also inside Sutton for planning drawing set purposes. |
| SM3 | Cheam / North Cheam | Georgian villas, 1930s semi-detached | Adjoining district to SM5, also inside Sutton for planning drawing set purposes. |
Roof pitch, wall build-up and plot depth change every few SM5 streets, and each one changes what a planning drawing set can achieve at that address.
SM5 (Carshalton) conservation designations: there are 17 across Sutton Council, Cheam Village, Sutton Central, Carshalton Village among them.

Cheam Village is the SM5 (Carshalton) designation that most often changes a planning drawing set design.
SM5 (Carshalton) permitted development status: there is no borough-wide direction from Sutton Council, so a planning drawing set at a SM5 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a SM5 (Carshalton) sale to argue it later.
