For the assembly of the oversized glass fins and panes, two suction units with counterweight and three-axial adjustment were developed specifically for this project. Only the specially developed suction systems made it possible to lift the glass into the final, double inclined position. During assembly, the glass fins were temporarily stabilized by custom-fit timber supports that formed the contour of the façade. Only when the façade panes were inserted, the façade became self-supporting. Particularly spectacular was the installation of glass fins which were inserted in one piece, featuring 24m heigth and a weight of 5t each.

Glass fins form the supporting structure for the suspended all-glass construction. These were assembled from parts with lengths of up to either 16m or 8m. Static fastening was on the ceiling at a height of 20m, above that, the construction cantilevers up to 4m to form a balustrade for the roof garden above. The façade comprises glass panes measuring up to 16m x 3,20m and 8m x 3,20m. The dead weight of the façade panes, which are up to 3.5t, is absorbed at the lower end of each pane by crosspieces, known as transoms. All steel components directly connected to the glass had to be designed as bolted connections in order to rule out accuracy losses due to welding distortion. There are six entrances along the façade, consisting of gold-colored stainless steel portals. These portals are necessary for static reasons in order to fix the doors and separate them from the suspended façade, so that the movements between the roof and floor can be absorbed.
