A district-by-district read of Merton: where we draw, the prevailing housing type, and the office that takes a drawing package from each address. Fee figures below come straight off the 2026 statutory England scale.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| SW19 | Wimbledon / Colliers Wood | Victorian villas, Edwardian terraces | Wimbledon and Colliers Wood sit either side of the SW19 line with Wandsworth, and that is settled plot by plot. |
| SW20 | Raynes Park | Victorian villas, Edwardian terraces | SW20 is Raynes Park alone; Merton handles it, with officers working to the conservation mapping drawn for that district. |
| SM4 | Morden | 1930s semi-detached, post-war flats | SM4 covers Morden only, so a package from there is validated and determined by Merton from start to finish. |
| CR4 | Mitcham | 1930s semi-detached, post-war estates | Mitcham lies wholly inside CR4, which keeps the whole process with one council, from validation through to the decision. |
| SW16 | Streatham / Norbury | Edwardian terraces, post-war flats | SW16 reaches into Lambeth, Wandsworth, Merton and Croydon, which makes the boundary check the first job on any Streatham or Norbury scheme. |
| SW17 | Tooting / Earlsfield | Edwardian terraces | SW17 through Tooting and Earlsfield is shared with Wandsworth, so the determining council is read off the address rather than the district. |
How steep a roof is, what the walls are built from and how far the garden runs back change from one Merton street to the next, and all three shape what a drawing package can propose.
How designation changes a Merton drawing package: Merton Council maintains 28 conservation areas, including Wimbledon Common, Wimbledon Village, John Innes. Inside any of them a Merton drawing package 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. Wimbledon Village sets the tone for Merton casework.
No borough-wide Article 4 here: permitted development survives across Merton outside conservation areas and listed curtilages, which makes a Lawful Development Certificate at £274 the sensible record for an SW19 owner to hold. Worth knowing alongside it: 246 of 735 larger householder prior approvals were refused over the same three years, so the deeper rear extensions are not waved through.
Merton housing stock: 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. Read that before choosing a drawing package route in Merton — construction, not postcode, sets what is achievable.
