Covering Richmond
Across SW14, TW1, TW7, TW8, TW9, TW10, we can visit, measure and advise. Nearby, we also take on projects in Isleworth (2 miles), Hounslow (2 miles), Barnes (3 miles), Roehampton (3 miles).
For homes towards Surrey, East Molesey is around 5 miles away. Across London, terraced houses with narrow side returns and tight access are the norm, which shapes everything from party wall notices to how materials reach the back garden.
Will the council need to approve it?
In England the main routes are permitted development (ideally confirmed with a lawful development certificate, £274), larger home extension prior approval (£249, 42 days) and a householder planning application (£548, normally 8 weeks), with council fees as set from 1 April 2026.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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).

Fixed written price

Build and sign-off
The build is managed from start to finish, inspected at each stage and signed off on completion.
Common questions in Richmond
Will my neighbours in Richmond be involved?

Do you cover all of Richmond?
Yes. We cover Richmond and the surrounding parts of Greater London. Site visits are free and there is no obligation.
How long does this take for a Richmond home?
8–13 weeks typical decision period, depending on the council and the complexity of the project.
What happens if planning is refused?
You can revise the design and reapply, or appeal. We read the officer’s report and tell you honestly which option has a better chance.

In England, from 1 April 2026 the council fee is £548 for a householder application, £274 for a lawful development certificate for a proposed extension and £249 for larger home extension prior approval. Our handling fee is separate.
