In collaboration with Frener&Reifer we executed the shop and fabrication design of the Durst Headquarters extension. The façades connect the historic low rise office building (By architect Othmar Barth) with a new modern tower (By architect Monovolume). The façades, based on the orientation, take advantage of different materials and technologies. The main facade is realized in aluminum panels characterized by double curvatures and punched windows placed in niches. The glass roof of the lower part twists becoming the tower’s glass façade. Our scope of work comprised the structural, thermal and acoustic engineering, the full design and 3dmodeling for the aluminum, steel and glass facades.
