The contract to design, fabricate and erect the complex roof structure was awarded to seele. Above the apartments, the roof covering consists of 1,900 glass and aluminium elements, every one of which has different dimensions and angles. Special sections have been developed for the opening lights, whose functions were simulated and tested in a 3D model. The 176 steel beams of the primary structure trace the organic form of this building. Like the roof covering, the beams could only be designed with the help of a 3D model because each one has a different geometry: The upper flanges all have different angles, the depths of the webs vary and the lower flanges are rounded. Plant rooms in the upper central area are enclosed in aluminium louvres – further unique elements.
This project enabled seele to demonstrate its extensive expertise in structural glazing directly on site. It is not only the high number of different components and the constraints of the site that call for sophisticated logistics. Installation, too, with 90% of the panes of glass being bent cold on site but still with the necessary accuracy, was extremely demanding.
