The trio of the Koopmans, Goosens and Cobbenhagen builings form a carefully considered ensemble in the campus of Tilburg university, designed by the architect Jos Bedaux. While retaining the original office spaces of the Koopmans building, the complete renovation will also offer the expansion of both the teaching and conference rooms as well as the accommodation of the Economics and Humanities faculties. Driving the renovation is the modern typology of the Koopmans building; the slab-shaped high-rise stands on ‘pilotis’ across the ground floor, with a central corridor on each level providing access to the individual offices along the façade. The masonry walls of this corridor are punctured with openings, allowing light to penetrate into the heart of the long, narrow plan. Consultation rooms and communal facilities are added along the corridor where the characteristic brickwork returns in perpendicular slabs, between which the offices are placed. The Koopmans building will form a new main entrance to the ensemble. To emphasize this role and strengthen the modern typology of the building, the ground floor offices have been replaced with a new seminar room and closed walls have been replaced with a series of glass curtain walls allowing both a new entrance into the building and enhancing this interior relationship with the exterior landscape.
