Extensions in and around Roehampton
We cover Roehampton and the postcode districts SW13, SW14, SW15. Neighbouring towns we cover include Putney (1 mile), Barnes (2 miles), Wimbledon (3 miles), Earlsfield (3 miles).
Just over the Surrey border, East Molesey is about 6 miles away. 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.
What it costs in Roehampton

Planning rules that apply in Roehampton
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.
The planning position for a specific Roehampton address depends on its history and any designations, which is why we check it at the first visit.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).

Common questions in Roehampton
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Roehampton, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Roehampton?
Yes. We cover Roehampton and the surrounding parts of Greater London. Site visits are free and there is no obligation.
How long does this take for a Roehampton home?
2–5 weeks for drawings, depending on the council and the complexity of the project.
Who are building control?
Either your local council’s building control team or a registered building control approver. Both inspect the work and issue the completion certificate.
What are the insulation standards for an extension?
In England, new walls in an extension should achieve a U-value of 0.18 W/m²K, roofs 0.15 and floors 0.18, with windows at 1.4 and rooflights at 2.2. Wales, Scotland and Northern Ireland set their own figures.
