The Koopmans building, together with the Goossens and Cobbenhagen buildings, form a monumental ensemble designed by architect Jos Bedaux. To accommodate the Faculty of Economics, the offices in the Koopmans building have been renovated and expanded with education and conference rooms. The typology of the Koopmans building has been leading in the renovation; a modernist high-rise slab on 'pilotis' in the landscape. The originally closed walls of the central corridor have been opened, allowing light to penetrate into the heart of the building and creating a relationship with the individual workspaces along the façade. Meeting spaces and communal facilities have been added to the corridor. The Koopmans building forms the new main entrance to the Bedaux ensemble. On the ground floor a glass curtain wall has replaced closed walls and a new seminar room at the head of the building has replaced offices. Thus reinforcing the typology of the building whilst creating a renewed orientation on the other buildings of the ensemble and the surrounding landscape of the Warandebos.
