Mace is main contractor on the £2bn scheme where construction started in 2020 for developer Caudwell.

John Cunningham, Chief Executive of Mivan, said: “Our appointment as principal contractor at 1 Mayfair reflects the confidence placed in Mivan to deliver projects of the highest calibre.

“These residences represent the very top of the super-prime market, and we are proud to be among the few contractors in London with the capability and experience to deliver residences of this standard in partnership with our esteemed client Caudwell.”

The appointment follows Mivan’s successful handover of The Chancery Rosewood, the transformation of the former US Embassy in Grosvenor Square into a luxury hotel.

Mivan was responsible for the fit-out of 144 suites, the Eagle Bar, and the central atrium, working with main contractor Multiplex and luxury developer Qatari Diar.
