Located in Endell Street, Covent Garden, the club was founded by musician Dave Stewart and co-founder of Microsoft and philanthropist, Paul Allen. It opened in 2004 following the transformation of the former St Paul's Hospital.
The new bedrooms intend to provide a twist on usual hotel amenities with inspiring turndown cards, brain power tool kits by the School of Life and erotic mini bars by Holloway Smith Noir.
Each of the new bedrooms will feature works of arts from contemporary artists and designers including Alyson Mowat's terrarium house plants and Rick Guest's portraits of Royal Ballet dancers.
Guests will also be able to make use of all member privileges including the club's art production and screening facilities, as well as enjoy events such as comedy nights, mixology classes, industry networking drinks and chef master classes.
Bedrooms will be available in four sizes: small, medium, large and suite, with bookings being taken from 5 January.
