Delivering in Mayfair
Mayfair works are rarely straightforward. Grade II listed terraces on Mount Street, floors in mansion blocks off Park Lane, family-office headquarters behind Georgian facades on Grosvenor Street. The pattern is consistent: expensive material, tight programme, private client, and no tolerance for a subcontracted trade turning up in the wrong colour van. We deliver with our own people.
Ushii is a London construction house working with private clients, family offices and developers across Mayfair 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 Mayfair clients ask.
Do you work under Grosvenor Estate consents?
Yes. Our project managers hold live relationships with Grosvenor's building surveyors and prepare licence-for-alteration submissions that go through without repeated queries.
Can you fit out a Mayfair club without interrupting service?
Yes. Works are phased around opening hours, protected from the main circulation and delivered in defined shutdown windows when a full stop is unavoidable.
What discretion do you offer for principals?
NDAs are signed at first meeting. Site records, photography and any post-completion imagery are shared only with the client's approval.
