Why Ushii in Holland Park
Ushii delivers extension work across Holland Park (W11 · W14) 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 Holland Park site are on our payroll, which is why programmes hold and standards stay consistent from strip out to snagging.
Holland Park is a village inside prime London. Family houses on Addison Road, garden-square terraces on Norland Square, laterals on Holland Park Avenue and Kensington Park Gardens. The clients are private, the programmes are honest, and the standard of finish is unforgiving. We build here often and take referrals from architects working on the same streets.
West London conservation areas control frontages, roof lines and window profiles closely. We design around those constraints rather than arguing with them after refusal.
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 Holland Park, answered.
How much does a extension cost in Holland Park?
Cost follows scope, access and the condition of the building rather than the postcode. After a survey in Holland Park 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 addison road detached houses in Holland Park?
Regularly. Addison Road detached houses, Norland conservation area terraces, Holland Park Avenue mansion flats all feature in our Holland Park workload, and each one is surveyed on its own terms before we price anything.
Which areas near Holland Park do you cover?
We work across Notting Hill, Kensington, Shepherd's Bush, Ladbroke Grove 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.
