Renowned London nightclub Annabel’s is to be given a new lease of life with plans to incorporate a range of leisure and wellness facilities as part of relocation proposals.

The basement nightclub in Mayfair, which has hosted the likes of Princess Diana, Sir Mick Jagger, Frank Sinatra, Kate Moss and Madonna in its 50-year existence, could soon be providing a substantially revamped offering. Restaurateur Richard Caring, who bought the club from founder Mark Birley in 2007 as part of a £95m deal, wants to move Annabel’s to larger premises two doors down from the current site and provide all-day amenities to members.

Plans submitted to Westminster City Council detail designs by architects Feilden+Mawson for a “high quality private members’ day and evening club.”

The new Annabel’s would include a modern private members’ health club, comprising a gym, medical and spa treatment rooms, private fitness studios, a sauna, steamroom and a club bar with healthy food offerings. This would sit alongside a revamped nightclub, plus a new daytime lounge and several dining areas.

The planning application states: “The client’s main aspiration is to develop the site to provide a high quality private members’ day and evening club by moving the iconic Annabel’s two doors down to no. 46 to provide new daytime lounge and dining spaces including terrace dining for current and future members whilst keeping Annabel’s at the heart of Berkeley Square."

Health Club Management has contacted operator Caprice Holdings for further details of the proposed health club.
