The building was designed by architect Richard Seifert and constructed as the Britannia Hotel by Grand Metropolitan Hotels from 1967 to 1969.[4] It has a classical red-brick facade facing Grosvenor Square, and a modern concrete, brick and glass facade facing the main entrance, on Adam's Row. The hotel was renamed the Britannia Inter-Continental London in 1981, after Grand Metropolitan acquired Inter-Continental Hotels.

The hotel was bought by Millennium & Copthorne Hotels on 7 October 1996 and renamed the Millennium Britannia Hotel.[5] It was renovated in 2000 and then renamed the Millennium Hotel London Mayfair.[6] The hotel's Pine Bar was the site of the poisoning of Alexander Litvinenko in 2006.[7]

The hotel was renovated again beginning in November 2017, at a cost of £50m. It closed in July 2018 and will reopen in 2019 as The Biltmore, Mayfair, operated by the LXR Hotels & Resorts luxury division of Hilton Hotels.[8]
