Room, designed by Anthony Gormley, at The Beaumont Hotel, Mayfair, London, UK

The bedroom of this unique suite occupies the interior of a giant semi-abstract sculpture by Antony Gormley, which dominates the entrance front of The Beaumont on Brown Hart Gardens. A dark, mysterious, cave-like space, ROOM encourages its occupants to enter a different state of consciousness, to enjoy at the very least a quiet, meditative pause, a prelude to a good night's sleep and the chance to withdraw, for a while, from the busy world outside. The wood-panelled bedroom is approached up stairs from the sitting room and the marble bathroom, which are decorated, like all the rooms in The Beaumont, in a soft Art Deco style. The suite is 69 square metres (745 square feet) in size, and also has a large private hallway and a guest bathroom. Source: thebeaumont.com
