Covering Morden
We cover Morden and the postcode districts CR4, SM1, SM3, SM4, SW19, SW20. Neighbouring towns we cover include Mitcham (1 mile), Wimbledon (2 miles), Worcester Park (2 miles), Tooting (2 miles).
Ewell, in Surrey, is roughly 4 miles from Morden 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.

Proportion matters on a porch more than on any other extension, because it is at the front. We match the roof pitch and brick and keep the front door in proportion with the house windows.
Planning and approvals in Morden
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.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
