A 190-key, 5-star hotel with restaurant, bar, conference facilities, spa and gym. 1 Hotel Mayfair is the UK flagship for Starwood’s sustainable luxury hotel brand.
The hotel is part new-build and part conversion of an existing 1970 building, thereby making large savings of embodied energy, carbon and site waste. The two new-build floors accommodate guestroom suites with views overlooking the Ritz Hotel and Green Park. Works to the existing building presented a number of challenges including mixed construction types and disparate floor levels that called for clever solutions.
The hotel is part of a 240,000 sq. ft. mixed-use project by Crosstree Real Estate Partners that includes sustainably-designed offices and prime retail.
