The division of the structure into a base area, main building and upper section is reflected by the three-dimensional treatment of the façade, which expresses the different functional zones of the building. “In the base area, the pillars are spaced 6.75 m apart and so provide ample transparency towards the outside for semi-public functions such as reception areas, conference rooms, training premises, cafés and a canteen,” explain the architects.
“The main structure above contains the office areas and is characterised by the sculptural and authoritative pillars spaced 1.35 m apart. The upper section of the building houses the technical areas and features more modest pillars spaced just 0.675 m apart. In this way, it is not only the volume of the building that is graduated, the structure of the façade is also progressively concentrated as it ascends, in keeping with the holistic design approach.”
