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.

Detailing for Belgravia houses

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.

Do I need planning permission for an extension in Belgravia?

Alongside planning and listed building consent, the estate's licence to alter governs everything from stucco colour to mews roof heights. 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 Belgravia?

Belgravia is covered by Westminster City Council. The Belgravia Conservation Area protects the white stucco terraces, the garden squares and the mews behind them as a single set piece.

How long does a project in Belgravia usually take?

Twelve to twenty months for a large stucco house including a basement.

What kind of properties do you work on in Belgravia?

Large white stucco houses, garden square terraces and mews properties, most of them held on Grosvenor Estate leases. Our Belgravia work is mainly full house refurbishment, basement and pool installations, stucco and stonework repair, and mews conversions.

Do you use subcontractors on Belgravia projects?

No. Every trade on site is directly employed by Ushii, so the people who price your Belgravia project are the people who build it.
