Why Ushii in St John's Wood
Ushii delivers extension work across St John's Wood (NW8) 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 St John's Wood site are on our payroll, which is why programmes hold and standards stay consistent from strip out to snagging.
St John's Wood is a detached villa market with a mansion-flat backdrop. Delivery here is about protecting the garden, working with the local planning department at Westminster City Council, and keeping neighbours in adjacent villas informed. Our teams have the postcode on the day book most weeks.
North London boroughs vary widely on permitted development, roof extensions and rear additions. We confirm what your specific street allows before drawings are paid for.
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 St John's Wood, answered.
How much does a extension cost in St John's Wood?
Cost follows scope, access and the condition of the building rather than the postcode. After a survey in St John's Wood 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 detached and semi-detached villas in St John's Wood?
Regularly. Detached and semi-detached villas, Avenue Road houses, Wellington Road mansion flats all feature in our St John's Wood workload, and each one is surveyed on its own terms before we price anything.
Which areas near St John's Wood do you cover?
We work across Regent's Park, Maida Vale, Marylebone, Hampstead 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.
