Planning Drawings · SW20 Raynes Park
Merton applies suburban householder control across SW20, with a conservation pocket around Cottenham Park; a settled family market.
This page covers one part of the borough. For the full picture — fees, timelines and the council's current position — read planning drawings in Merton.
Planning drawings for Raynes Park start by establishing whether your scheme is Permitted Development, needs a Lawful Development Certificate, or full planning from Merton Council. On SW20's inter-war and edwardian semis and detached houses, the recurring questions are roof additions, rear and side-return extensions, and alterations within Cottenham Park, Wimbledon West Side fringe. We draw existing and proposed plans, elevations and a site location plan to the council's validation checklist for Raynes Park, West Wimbledon, Cottenham Park, Motspur Park fringe.
Across Raynes Park, West Wimbledon, Cottenham Park, Motspur Park fringe in SW20, the dominant property is inter-war and edwardian semis and detached houses around raynes park and west wimbledon, with larger houses toward wimbledon common. 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 Merton Council judges each on design quality and neighbour impact. We survey the specific Raynes Park property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SW20 streetscape.

Getting around SW20: Raynes Park and Motspur Park rail to Waterloo, plus Wimbledon nearby for the District line and tram.
Property values: around £400,000 for a flat and £800,000-£1.3m for a house — a useful gauge of the build value an extension or loft adds in SW20.
Borough character: Wimbledon is heavily conservation-controlled; outer Merton (Morden, Mitcham) is permissive.

Planning + building regs + structural.
Listed, conservation or complex sites.
Yes. The inter-war and Edwardian semis and detached houses around Cottenham Park and Grand Drive suit rear, side and double-storey extensions plus loft conversions, much of it within Permitted Development outside the conservation area, confirmed with a Lawful Development Certificate. We confirm the route and draw to Merton's checklist.
Often, on the wider semi and detached plots around Coombe Lane — a two-storey side or rear extension, subject to Merton's design and neighbour-amenity policy on side-space and daylight. We design within those limits and produce the planning and Building Regulations drawings together.
Usually yes on the semis — a hip-to-gable plus rear dormer within the volume allowance, confirmed by a Lawful Development Certificate, provided you're not in the Cottenham Park conservation area. We check the constraints for your road and draw it for Building Control.
With SW20 houses around £800,000-£1.3m and direct rail links to Waterloo, a rear extension or loft adds family space worth comfortably above the build and drawing cost. SW20 is a sought-after family suburb.
With Raynes Park property at around £400,000 for a flat and £800,000-£1.3m for a house, the professional drawing fee is a small fraction of the value the work adds to SW20's inter-war and edwardian semis and detached houses. Merton 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 SW20 address.
For a SW20 project across Raynes Park, West Wimbledon, Cottenham Park, Motspur 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 Merton Council (8 weeks for a householder application). We carry the Raynes Park application through every officer query to the decision.
Raynes Park (SW20) sits primarily in Merton, so applications are decided by Merton Council. Conservation areas within SW20 include Cottenham Park, Wimbledon West Side 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 Raynes Park — 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 Merton Council Building Control or an approved inspector. On SW20'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 Raynes Park (SW20) property at around £400, 000 for a flat and £800, 000-£1.3m for a house, 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 SW20 homes.

Every SW20 postcode district we draw in, the stock that dominates it and the authority that validates a planning drawing set there. SW20 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 |
|---|---|---|---|
| SW20 | Raynes Park | Victorian villas, Edwardian terraces | A planning drawing set at an SW20 address in Raynes Park is determined by Merton Council under its own Local Plan policies for Raynes Park. |
| SW20 | Wimbledon | Victorian villas, Edwardian terraces | Wimbledon sits inside SW20; planning drawing set proposals here are determined by Merton Council. |
| SW19 | Wimbledon / Colliers Wood | Victorian villas, Edwardian terraces | Adjoining district to SW20, also inside Merton for planning drawing set purposes. |
| SM4 | Morden | 1930s semi-detached, post-war flats | Adjoining district to SW20, also inside Merton for planning drawing set purposes. |
| CR4 | Mitcham | 1930s semi-detached, post-war estates | Adjoining district to SW20, also inside Merton for planning drawing set purposes. |
Roof pitch, wall build-up and plot depth change every few SW20 streets, and each one changes what a planning drawing set can achieve at that address.
Conservation areas covering SW20 (Raynes Park): Merton Council runs 28, and Wimbledon Common, Wimbledon Village, John Innes are the ones SW20 (Raynes Park) owners meet most. A planning drawing set inside a SW20 (Raynes Park) conservation area loses permitted development, so the SW20 (Raynes Park) submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Wimbledon Common a planning drawing set is judged on the street elevation first.
SW20 (Raynes Park) permitted development status: there is no borough-wide direction from Merton Council, so a planning drawing set at a SW20 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a SW20 (Raynes Park) sale to argue it later.
The building fabric around SW20 (Raynes Park): Victorian villas in Wimbledon; Edwardian terraces in Tooting and Colliers Wood; 1930s semi-detached in Morden and Raynes Park; post-war flats in Mitcham. Wimbledon is heavily conservation-controlled; outer Merton (Morden, Mitcham) is permissive. A planning drawing set in SW20 (Raynes Park) 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 Merton Council.
