Nestled beneath the vaults of the London Palladium, Mason House opens as London's most exquisite nightlife offering. Taking its namesake from 1737, at which point the majority of residents on Argyll Street were Masons, and as such, the interior designers intended to create a space that resembles a Masonic Temple. This Argyll Street party venue boasts exposed brick arches, leather banquet seating and Victorian-style oak wood bars as well as other original features, all of which have been restored to their original glory to give the space a contemporary feel.

Entering through the crypt, guests can spend their time in the Main Club Room, complete with a black and white checkered dance floor and table service; alternatively, Room 33 offers an alternative music room, with a secret entrance, operating on an invitation only basis. Mason House plays host to some of the most exclusive musicians from across the world, pumping out an eclectic mix of genres on the Funktion 1 state of the art sound system. Mason House also showcases art from young, up-and-coming artists from across the UK.
