Planning Drawings · SM3 Cheam
Sutton protects the Cheam Village conservation area, with its historic core and timber-framed survivors, alongside standard suburban householder control across the rest of SM3.
This page covers one part of the borough. For the full picture — fees, timelines and the council's current position — read planning drawings in Sutton.
Planning drawings for Cheam start by establishing whether your scheme is Permitted Development, needs a Lawful Development Certificate, or full planning from Sutton Council. On SM3's inter-war bay-fronted semis and terraces around cheam, the recurring questions are roof additions, rear and side-return extensions, and alterations within Cheam Village. We draw existing and proposed plans, elevations and a site location plan to the council's validation checklist for Cheam, North Cheam, Stonecot, Worcester Park fringe.
Across Cheam, North Cheam, Stonecot, Worcester Park fringe in SM3, the dominant property is inter-war bay-fronted semis and terraces around cheam and north cheam, with larger houses toward nonsuch 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 Cheam property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SM3 streetscape.

Because SM3 is a settled family suburb of inter-war bay-fronted semis around Cheam and North Cheam — ideal for rear and side extensions and hip-to-gable loft conversions. Outside the Cheam Village conservation area, much of the work runs on the Permitted Development route, confirmed with a Lawful Development Certificate.
Yes — the Cheam Village conservation area protects the historic core, including timber-framed survivors and the Whitehall house setting, so external changes there need full planning with a Heritage Statement. We design sympathetically and handle the Sutton application.
Usually yes on the semis outside the conservation area — a hip-to-gable plus rear dormer within the volume allowance, confirmed by a Lawful Development Certificate. We check the head height and any constraint near Cheam Village, then draw for Building Control too.
With SM3 houses around £550,000-£850,000 and direct trains to Victoria and London Bridge, a rear or loft extension adds family space worth above the build and drawing cost. Cheam offers green, village-edge living at strong value.
Sutton 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 SM3 address.
For a SM3 project across Cheam, North Cheam, Stonecot, Worcester Park 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 Sutton Council (8 weeks for a householder application). We carry the Cheam application through every officer query to the decision.
Cheam (SM3) sits primarily in Sutton, so applications are decided by Sutton Council. Conservation areas within SM3 include Cheam Village, 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 Cheam — 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 SM3'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 SM3 homes.
Householders often approach us after a neighbour used a different council. Our full range is set out for SM1, SM2 and SM5.
Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every SM3 postcode district we draw in, the stock that dominates it and the authority that validates a planning drawing set there. SM3 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 |
|---|---|---|---|
| SM3 | Cheam / North Cheam | Georgian villas, 1930s semi-detached | A planning drawing set at an SM3 address in Cheam / North Cheam is determined by Sutton Council under its own Local Plan policies for Cheam / North Cheam. |
| SM3 | Cheam | Georgian villas, 1930s semi-detached | Cheam sits inside SM3; planning drawing set proposals here are determined by Sutton Council. |

| SM1 | Sutton | Edwardian terraces, 1930s semi-detached | Adjoining district to SM3, also inside Sutton for planning drawing set purposes. |
| SM2 | Sutton / Belmont | Georgian villas, 1930s semi-detached | Adjoining district to SM3, also inside Sutton for planning drawing set purposes. |
Roof pitch, wall build-up and plot depth change every few SM3 streets, and each one changes what a planning drawing set can achieve at that address.
How designation changes a SM3 (Cheam / North Cheam) planning drawing set: Sutton Council maintains 17 conservation areas, including Carshalton Village, Beddington Park, Cheam Village. Inside any of them a SM3 (Cheam / North Cheam) planning drawing set cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Beddington Park sets the tone for SM3 (Cheam / North Cheam) casework.

A Lawful Development Certificate at £274 is how a SM3 owner records that a planning drawing set was lawful.
