Planning Drawings · SM2 Sutton
Sutton applies careful householder control across SM2, a higher-value market of larger inter-war houses, with the Sutton Garden Suburb conservation interest nearby.
The borough-level guide to planning drawings in Sutton sets out how the same work is handled across the rest of the authority.
Planning drawings for Sutton start by establishing whether your scheme is Permitted Development, needs a Lawful Development Certificate, or full planning from Sutton Council. On SM2's larger inter-war and edwardian detached and semi-detached, the recurring questions are roof additions, rear and side-return extensions, and alterations within Sutton Garden Suburb (fringe). We draw existing and proposed plans, elevations and a site location plan to the council's validation checklist for Sutton, Belmont, South Sutton, Banstead fringe.
Across Sutton, Belmont, South Sutton, Banstead fringe in SM2, the dominant property is larger inter-war and edwardian detached and semi-detached houses around sutton and belmont, with leafy plots toward the surrey fringe. 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 Sutton property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SM2 streetscape.

Because SM2 is a higher-value market of larger inter-war and Edwardian detached and semi-detached houses on generous plots — ideal for substantial rear, side and wrap-around extensions and loft conversions. The wider plots give scope, and much runs on the Permitted Development route, confirmed with a Lawful Development Certificate.
Usually yes on the detached and semi-detached houses — a hip-to-gable plus rear dormer within the 50 cubic metre allowance, confirmed by a Lawful Development Certificate. The generous SM2 roofs often give excellent head height. We draw the scheme for Building Control too.
Often, given the larger SM2 plots — a two-storey side extension or a deep wrap-around, subject to Sutton's design and neighbour-amenity policy on daylight and plot coverage. We design within those limits and produce the planning and Building Regulations drawings together.
With SM2 houses around £600,000-£1m, a well-designed extension or loft adds significant family space and value in one of Sutton's most sought-after areas. The larger plots reward ambitious schemes.
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 SM2 address.
For a SM2 project across Sutton, Belmont, South Sutton, Banstead 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 Sutton application through every officer query to the decision.
Sutton (SM2) sits primarily in Sutton, so applications are decided by Sutton Council. Conservation areas within SM2 include Sutton Garden Suburb (fringe), 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 Sutton — 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 SM2'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 SM2 homes.

Every SM2 postcode district we draw in, the stock that dominates it and the authority that validates a planning drawing set there. SM2 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 |
|---|---|---|---|
| SM2 | Sutton / Belmont | Georgian villas, 1930s semi-detached | A planning drawing set at an SM2 address in Sutton / Belmont is determined by Sutton Council under its own Local Plan policies for Sutton / Belmont. |
| SM2 | Cheam | Georgian villas, 1930s semi-detached | Cheam sits inside SM2; planning drawing set proposals here are determined by Sutton Council. |
| SM2 | Belmont | 1930s semi-detached | Belmont sits inside SM2; planning drawing set proposals here are determined by Sutton Council. |
| KT4 | Worcester Park | 1930s semi-detached | Adjoining district to SM2, also inside Sutton for planning drawing set purposes. |
| SM1 | Sutton | Edwardian terraces, 1930s semi-detached | Adjoining district to SM2, also inside Sutton for planning drawing set purposes. |
| SM3 | Cheam / North Cheam | Georgian villas, 1930s semi-detached | Adjoining district to SM2, also inside Sutton for planning drawing set purposes. |
Roof pitch, wall build-up and plot depth change every few SM2 streets, and each one changes what a planning drawing set can achieve at that address.
Conservation areas covering SM2 (Sutton / Belmont): Sutton Council runs 17, and Cheam Village, Sutton Central, Carshalton Village are the ones SM2 (Sutton / Belmont) owners meet most. A planning drawing set inside a SM2 (Sutton / Belmont) conservation area loses permitted development, so the SM2 (Sutton / Belmont) submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Carshalton Village a planning drawing set is judged on the street elevation first.
No blanket Article 4 over SM2 (Sutton / Belmont): Sutton Council has not withdrawn permitted development across SM2 (Sutton / Belmont), so a planning drawing set outside a SM2 (Sutton / Belmont) conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a SM2 owner wants on file.
The building fabric around SM2 (Sutton / Belmont): 1930s semi-detached dominates; Edwardian terraces and villas in Sutton central; Victorian cottages in Carshalton; post-war in Hackbridge. Outer south London suburban; generally permissive; Carshalton and Cheam conservation areas add heritage in pockets. A planning drawing set in SM2 (Sutton / Belmont) is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Sutton Council.
