The solution by renowned architectural firm MRLV was to replace the old, ailing roof truss with a steel-free construction. The architect collaborated with the structural engineer Stefan Heidrich from WTM Engineers, and they developed a roof design without any load bearing metal supports or joints.
Any metal joints that can still be seen today only served as an assembly aid, and they remain there without static importance. According to Voss, ”Industrially manufactured, dimensionally stable Kerto® LVL (laminated veneer lumber) helped us to achieve an efficient solution. We were thus able to develop an object-specific design that meets both the static and the economic requirements.”
