Why Ushii in Islington
Ushii delivers extension work across Islington (N1) 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 Islington site are on our payroll, which is why programmes hold and standards stay consistent from strip out to snagging.
Islington's Georgian and early Victorian townhouse stock is some of the finest in London. Delivery in Canonbury, Barnsbury and around Duncan Terrace means running work under LB Islington's conservation controls, protecting original joinery and cornicing, and coordinating tightly with neighbours on narrow streets. Our directly employed teams work here throughout the year.
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 Islington, answered.
How much does a extension cost in Islington?
Cost follows scope, access and the condition of the building rather than the postcode. After a survey in Islington 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 canonbury square and de beauvoir georgian townhouses in Islington?
Regularly. Canonbury Square and De Beauvoir Georgian townhouses, Barnsbury and Thornhill Square terraces, Duncan Terrace and Colebrooke Row houses all feature in our Islington workload, and each one is surveyed on its own terms before we price anything.
Which areas near Islington do you cover?
We work across Highbury, Barnsbury, Canonbury, Clerkenwell, De Beauvoir 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.
