A new home for the theatre group MC was made in the former ‘East Purification Hall’ on Westergasfabriek’s terrain in Amsterdam. This production house is for young theatre-makers, to make new developments in the studios and room to make audio and visual recordings, to rehearse, to assemble and present. The heart of the monument is the ‘black box’ auditorium. This space can be used in different ways with a flexible wall and flexible seating. A 125-year old crane, from this terrain was used for the structure. The auditorium and other spaces hang on this crane.
