Additions that read as if they were always there.
Why Ushii in Chiswick
Ushii delivers extension work across Chiswick (W4) 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 Chiswick site are on our payroll, which is why programmes hold and standards stay consistent from strip out to snagging.
Chiswick is a mature family-house market with strong conservation cover. Delivery here is about detailing extensions that read as if they were always there, refurbishing Bedford Park houses without spoiling the woodwork, and running the job to a programme the family can live around.
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 Chiswick, answered.
How much does a extension cost in Chiswick?
Cost follows scope, access and the condition of the building rather than the postcode. After a survey in Chiswick 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 bedford park arts and crafts houses in Chiswick?
Regularly. Bedford Park Arts and Crafts houses, Grove Park detached houses, Chiswick Mall riverside houses all feature in our Chiswick workload, and each one is surveyed on its own terms before we price anything.
Which areas near Chiswick do you cover?
We work across Kew, Barnes, Hammersmith, Acton 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.
