Urs Raussmüller’s architectural project convincingly combined simplicity, aesthetics and practical function. The first stage was to reduce the Casino to its elementary structures. Then followed the installation, in every one of the heightened ground floor and first floor rooms (the central entrance hall excepted) of open-top cubes made of uniformly white walls. This minimal, but clear and purposeful intervention simultaneously fulfilled various requirements. The historical substance of the building remained untouched, and the budget that this restructuring entailed was relatively modest. Because they offered a maximum of wall space, the cubes proved to be ideal exhibition spaces. Moreover, the walls protected the fragile artworks from ultraviolet radiation emitted through the natural light. Finally, the cubes formed coherent and homogenous entities that could be easily removed at the end of the cultural year. In total, thirteen rooms had been recast in the building. Taken together, they represented a floor surface of 460 m2 and a wall length of 290 m.

The entrance hall, finally, is also a reception area, equipped with all the necessary furnishings to inform the visitor and sell tickets and catalogues.
