Wimbledon is Victorian villas, Edwardian terraces. The streetscape is dominated by victorian villas, edwardian terraces, which means design decisions — roofscape, rear glazing, side returns, mansards — must respect the period rhythm of the row. Merton planning (Merton Council) decides applications here. Most permitted development rights apply normally in Merton for residential extensions.

Wimbledon sits within Merton, so applications are decided by Merton Council. Most single-storey rear extensions and side-returns on terraced or semi-detached homes in Wimbledon fall under Permitted Development — up to 3m deep (attached) or 4m (detached), under 4m high. Flats, listed buildings and conservation areas always require full planning. Article 4 status here: No. We check eligibility free at the site visit.

Every Wimbledon postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Wimbledon fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| SW19 | Wimbledon / Colliers Wood | Victorian villas, Edwardian terraces | A drawing package in Wimbledon / Colliers Wood may land with Merton Council or Wandsworth Council — SW19 crosses the boundary, and the SW19 policies map decides it street by street. |
| SW20 | Raynes Park | Victorian villas, Edwardian terraces | SW20 covers Raynes Park only; Merton Council handles the drawing package, and Raynes Park case officers apply the SW20 conservation-area map. |
| SW19 | Wimbledon Village | Georgian and Victorian villas | Neighbouring Wimbledon Village, where drawing package work is handled by the same Merton Council case officers. |
| SM4 | Morden | 1930s semi-detached, post-war flats | Neighbouring Morden, where drawing package work is handled by the same Merton Council case officers. |
| CR4 | Mitcham | 1930s semi-detached, post-war estates | Neighbouring Mitcham, where drawing package work is handled by the same Merton Council case officers. |
| SW19 | Colliers Wood | Edwardian terraces, post-war flats | Neighbouring Colliers Wood, where drawing package work is handled by the same Merton Council case officers. |
| SW19 | South Wimbledon | Edwardian terraces | Neighbouring South Wimbledon, where drawing package work is handled by the same Merton Council case officers. |
Roof pitch, wall build-up and plot depth change every few Wimbledon streets, and each one changes what a drawing package can achieve at that address.
How designation changes a Wimbledon drawing package: Merton Council maintains 28 conservation areas, including Wimbledon Village, John Innes, Mitcham Cricket Green. Inside any of them a Wimbledon drawing package cannot rely on permitted development, and the route becomes a £258 householder application determined in 8 weeks rather than a £120 prior approval in 6 weeks. Mitcham Cricket Green sets the tone for Wimbledon casework.
No blanket Article 4 over Wimbledon: Merton Council has not withdrawn permitted development across Wimbledon, so a drawing package outside a Wimbledon conservation area usually keeps it. The £129 Lawful Development Certificate is still the document a SW19 owner wants on file.
