Delivering in Barnet
Barnet is a substantial family-house market. Hadley Wood, Totteridge Village and Cockfosters carry some of the largest detached houses in North London, and the borough's planning department is used to well-drawn extensions and basement schemes. Our teams are drawn from neighbouring Enfield and work across the borough on whole-house refurbishments, side and rear extensions and lower-ground reconfiguration.
Ushii is a London construction house working with private clients, family offices and developers across Barnet and the surrounding prime postcodes. Every project is delivered by our own directly employed teams under a single point of accountability from first survey to final handover.

Answers
What Barnet clients ask.
Do you work in Hadley Wood?
Yes. Hadley Wood is one of our regular delivery areas, along with Cockfosters, Totteridge and Monken Hadley.
How do you handle LB Barnet planning?
We prepare clean submissions and respond to officer queries inside the borough's standard timelines. Larger schemes get pre-app engagement before submission.
Can you deliver a Hadley Wood pool?
Yes. Pool tanking, plant and coordination with pool consultants and landscape architects are handled by our project management team.
Do I need planning permission for an extension in Barnet?
Barnet supports extensions and loft conversions on most suburban stock, though replacement dwellings and Green Belt sites need a more careful approach. We confirm the position for your specific address before any design work begins, including whether the property sits inside a conservation area or carries an Article 4 direction.
Which council covers Barnet?
Barnet is covered by the London Borough of Barnet. Monken Hadley, Wood Street and Totteridge are conservation areas, with Green Belt policy affecting parts of the northern edge.
How long does a project in Barnet usually take?
Four to seven months for extensions, six to ten for a substantial refurbishment.
What kind of properties do you work on in Barnet?
Detached and semi-detached inter-war houses, larger modern houses in Totteridge, and Victorian cottages around Chipping Barnet. Our Barnet work is mainly large rear and side extensions, loft conversions, garage conversions, and full property refurbishment.
Do you use subcontractors on Barnet projects?
No. Every trade on site is directly employed by Ushii, so the people who price your Barnet project are the people who build it.
