Why Ushii in Richmond
Ushii delivers extension work across Richmond (TW9 · TW10) with directly employed trades. Not a broker, not a list of numbers passed to whoever is free that week. The carpenters, roofers, electricians and gas engineers on your Richmond site are on our payroll, which is why programmes hold and standards stay consistent from strip out to snagging.
Richmond is family-house country. Detached houses backing onto the park, Georgian terraces on the Green, listed cottages on the hill. Delivery here is about respecting the streetscape, working within Richmond upon Thames' conservation policies and getting the family back in before the next school term.
South west London boroughs are generally pragmatic, but river proximity, tree preservation orders and conservation area status all shape what gets consented. We check the constraints before you commit.
The best extensions do not announce themselves. Brick coursing lines up. Ridge heights sit down. New glazing frames the garden without stealing focus from the original house. We build extensions the way conservation officers wish everyone did.

Common questions
House extensions in Richmond, answered.
How much does a extension cost in Richmond?
Cost follows scope, access and the condition of the building rather than the postcode. After a survey in Richmond we issue a fixed, itemised price so you can see exactly what each element of the extension carries. There are no provisional sums hidden in the back pages.
Do you work on georgian houses on richmond green in Richmond?
Regularly. Georgian houses on Richmond Green, Detached family houses on Richmond Hill, Petersham cottages all feature in our Richmond workload, and each one is surveyed on its own terms before we price anything.
Which areas near Richmond do you cover?
We work across Kew, Petersham, East Sheen, Twickenham, Ham and the wider London area, with a directly employed team rather than local trades brought in for the day.
Do we need planning permission?
Many rear extensions fall under permitted development. Anything on a listed building, in a conservation area or beyond PD limits will need consent. We assess this at feasibility.
How do you match old brickwork?
We take physical samples to a handmade brick supplier and dry-lay panels for you to approve before ordering.
