Delivering in Islington
Islington's Georgian and early Victorian townhouse stock is some of the finest in London.

Our directly employed teams work here throughout the year.

Answers
What Islington clients ask.
Do you work with LB Islington conservation officers?
Yes. Canonbury, Barnsbury and Duncan Terrace all sit in conservation areas. We prepare clean submissions and manage the officer relationship through consents.
Can you build a basement under an Islington terrace?
Yes, where the ground and party-wall position allows. We coordinate structural engineering, BIA and party-wall awards before ground breaks.
How do you handle neighbours on a Canonbury Square job?
Party-wall notices go out early, we hold noisy trades to agreed hours, and one project manager owns the neighbour relationship for the duration of the job.
Do I need planning permission for an extension in Islington?
Islington enforces conservation policy firmly, particularly on front elevations, windows and roof extensions visible from the street. 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 Islington?
Islington is covered by the London Borough of Islington. Canonbury, Barnsbury and the squares around Upper Street are conservation areas, and Article 4 directions remove permitted development rights across much of the borough.
How long does a project in Islington usually take?
Five to nine months for a terrace refurbishment, longer with a basement.
What kind of properties do you work on in Islington?
Georgian terraces around the squares, Victorian terraces and warehouse conversions off the canal. Our Islington work is mainly rear extensions, basement lowering and underpinning, full refurbishment and loft conversions to the rear.
Do you use subcontractors on Islington projects?
No. Every trade on site is directly employed by Ushii, so the people who price your Islington project are the people who build it.
