The new 96-bedroom hotel currently under development at Admiralty Arch in London will fly the Waldorf Astoria Hotels & Resorts flag when it opens in 2022.
The sale of Admiralty Arch to private developers was part of a wider sell-off of unused government buildings back in 2012.
Admiralty Arch Waldorf Astoria will have three restaurants plus a rooftop bar, meeting and events space and a spa.
Waldorf Astoria will share the building with private residences and a private members club.
Hotel design will be led by Michael Blair and David Mlinaric.
