From the beginning of the 1960s Utrecht University campus has been located outside the city, on the De Uithof terrain. A master plan by OMA/Rem Koolhaas from the early 1990s designated zones to be filled with high-density development to spare the landscape. Each zone has been given a character of its own. The Faculty for Economics and Management, for five thousand students and four hundred staff, lies in a zone known as the ‘Casbah’. Based on the notion of this traditional North African form of settlement, the long shallow building has only three storeys with a neutral facade enclosing a sheltered world of patios, rooms, halls, footbridges, stairs and leisure places.
