Every Merton postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Merton 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. |
| SM4 | Morden | 1930s semi-detached, post-war flats | SM4 covers Morden only; Merton Council handles the drawing package, and Morden case officers apply the SM4 conservation-area map. |
| CR4 | Mitcham | 1930s semi-detached, post-war estates | Mitcham sits wholly inside CR4, so Merton Council validates every drawing package submitted from an CR4 address. |
| SW16 | Streatham / Norbury | Edwardian terraces, post-war flats | SW16 straddles a boundary: Streatham / Norbury addresses fall to Lambeth Council or Wandsworth Council or Merton Council or Croydon Council, so confirm which authority validates the drawing package before submitting SW16 drawings. |
| SW17 | Tooting / Earlsfield | Edwardian terraces | SW17 straddles a boundary: Tooting / Earlsfield addresses fall to Wandsworth Council or Merton Council, so confirm which authority validates the drawing package before submitting SW17 drawings. |
Roof pitch, wall build-up and plot depth change every few Merton streets, and each one changes what a drawing package can achieve at that address.
How designation changes a Merton drawing package: Merton Council maintains 28 conservation areas, including Wimbledon Village, John Innes, Mitcham Cricket Green. Inside any of them a Merton 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. Wimbledon Common sets the tone for Merton casework.
No blanket Article 4 over Merton: Merton Council has not withdrawn permitted development across Merton, so a drawing package outside a Merton conservation area usually keeps it. The £129 Lawful Development Certificate is still the document a SW19 owner wants on file.
The building fabric around Merton: 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 drawing package in Merton is scoped against that stock first. Our Merton fixed fee starts at £840; the £1,750 Complete package runs the Merton scheme through Merton Council planning and building control in one go.
