[1] The hotel has a 19th-century façade, being the former Queen Anne's Chamber, a Second World War-time residence of lobbyists and civil servants.

The building was renovated in 2014 to be London's first Conrad Hotel, part of the Hilton Worldwide group.

[2] Artwork at the hotel includes Chris Levine's 'Lightness of Being' a holographic portrait of Queen Elizabeth II and a large sculpture entitled 'The House Always Wins' by Evil Ed and Dan Robotic.

It was the war-time location in Westminster for those lobbyists and civil servants whose industries faced dramatic impact from the onset of war.

One of the earliest tenants of note was The Brewers' Society, who between 1909 and 1917 took premises in Queen Anne's Chambers to engage government with its growing concern over the output of beer and imposed limits on the use of sugar in brewing at a time of rationing.
