Why Ushii in Winchmore Hill
Ushii delivers extension work across Winchmore Hill (N21) 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 Winchmore Hill site are on our payroll, which is why programmes hold and standards stay consistent from strip out to snagging.
Winchmore Hill and neighbouring Grange Park hold some of North London's most substantial family houses. The Green conservation area sits at the heart of the village, and the surrounding streets run to large detached houses that benefit from proper refurbishment and considered extension. Our Enfield-based team works in N21 constantly.
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 Winchmore Hill, answered.
How much does a extension cost in Winchmore Hill?
Cost follows scope, access and the condition of the building rather than the postcode. After a survey in Winchmore Hill 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 winchmore hill green conservation area houses in Winchmore Hill?
Regularly. Winchmore Hill Green conservation area houses, Grange Park mock-Tudor detached houses, Bush Hill Park Edwardian houses all feature in our Winchmore Hill workload, and each one is surveyed on its own terms before we price anything.
Which areas near Winchmore Hill do you cover?
We work across Enfield, Southgate, Palmers Green, Grange Park, Bush Hill Park 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.
