Working in Wimbledon
Our survey diary covers Wimbledon, including CR4, SM4, SW17, SW18, SW19, SW20. Nearby, we also take on projects in Morden (2 miles), Earlsfield (2 miles), Tooting (2 miles), Mitcham (2 miles).
Ewell, in Surrey, is roughly 5 miles from Wimbledon and also on our list. In London, space is at a premium and gardens are often short, so side returns, wraparounds and carefully planned rear extensions tend to make the most of every metre.

Do I need planning permission in Wimbledon?
In England a porch is usually permitted development if its ground floor area is no more than 3 m² measured externally, no part is over 3 m high, and no part is within 2 m of a boundary next to a road.
The planning position for a specific Wimbledon address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
