Porcelænshaven, the fourth main building that comprises the CBS campus, is leased by CBS from the Danish Society for the Advancement of Business Education. Formerly the Royal Copenhagen Porcelain Factory, the factory has been converted into 20,000 m2 of student classrooms, study spaces, offices, and a student residence. A central feature of the building, a 1,000 m2 main hall used for large events, stands in the old location of the factory kiln hall. As part of the factory conversion, Henning Larsen Architects transformed the old raw material storage building into 3,800 m2 of modern study space.
