Delivering in Belgravia
Belgravia is where the basement code, the party wall surveyors and the discretion of the client converge. Delivery here is about doing the difficult work quietly. Our teams work Eaton Square, Chester Square, Belgrave Square and the Wilton Crescent side streets on a repeat basis, and know how to run a two-year job on a garden-square terrace without becoming the reason a neighbours' association is set up.
Ushii is a London construction house working with private clients, family offices and developers across Belgravia 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 Belgravia clients ask.

Are you a Grosvenor Estate approved contractor?
We work under Grosvenor licences for alteration regularly. Our project managers know the surveyors and the standard conditions applied to Belgravia leases.
How do you manage a basement in a Belgravia terrace?
Structural engineer led scheme, sequenced pin and underpin, party wall awards in place before excavation, and a full BIA where required. Neighbour liaison runs weekly for the duration of the excavation.
What's a realistic budget for a whole-house Belgravia project?
For a full refurbishment without a new basement, £1.5m to £4m depending on floor area and specification. With a double-storey basement, expect £4m to £10m plus.
