Maurice Mentjens developed a multifunctional retail layout for the new entrance area. The cash desk and the presentation units echo the elemental architecture of Aldo Rossi, the designer of the museums building: cubes, beams, and cylinders. Maurice Mentjens is an admirer of Rossi's ideas on architecture. All his designs are constructed with elemental contours, predominantly powerful geometric figures: cubes, beams, and cylinders. We have continued along the same architectural lines.’  The telescopic inner tower of the central entrance hall is echoed in the cash desk design. It's like a bandstand or a well on an adjacent city square. The circular form is split into three functional segments: admission ticket sales, shop, and the art lending library. The pedestal in the centre is crowned with a palm plant. This is a nod to the conceptual potted palm assemblage by Marcel Broodthaers which is part of the Basic Collection. A comparable collage is grouped around the cash desk: three circular presentation disks plus a tall, white pillar on which posters can be displayed. The elongated wooden pyramid forms a counterbalance to these. It is a reinterpretation of the stone sculpture by Sol LeWitt that adorns one of the internal courtyards.
