Rosewood Hotels and Resorts has revealed its upcoming hotel in the former US Embassy in London's Mayfair will be called the Chancery Rosewood.
The site is due to open in 2024 and is being developed in partnership with property company Qatari Diar.
The Grade II-listed building was designed by Finnish architect Eero Saarinen and opened in 1960. It was the first purpose-built chancery in London and housed the US Embassy until 2017.
Once complete the new hotel will include 139 rooms and suites, dining areas, an Asaya wellness facility, five retail outlets, meetings and events spaces, and a 750-capacity ballroom.
Its interiors will be designed by French architect Joseph Dirand, a "longtime admirer of Saarinen".
A press statement from Rosewood said: "Taking inspiration from the sophistication of the 1920s and the creativity and glamour of the 1960s, the design scheme will draw from a warm, rich colour palette and feature refined, Art Deco-style detailing, walnut panelling and marble and brass accents, altogether channelling the ambiance of a traditional British gentlemen's club."
Rosewood expects the hotel to be the first in the UK to receive a BREEAM outstanding rating for sustainable development.
It will be Rosewood's second hotel in London and sixth in Europe. The company manages 27 luxury hotels, resorts and residences worldwide.
Rosewood recently pulled out of plans to transform the Royal High School site in Edinburgh into a hotel after proposals were rejected by the council.
