This article describes the first full-scale realization of a double-layered, folded plate structure (DLFP), for a new hall for the Théâtre Vidy Lausanne. (Fig. 1). Enabled by a novel double-tenon connection technology, the shape of the components simultaneously serves as a joining aid for rapid and precise assembly, as well as for a direct transfer of the forces between the plates and in between the two layers of the construction. This is made possible by project-specific CAD plugins. These allow an algorithmic generation of the component geometries and the CNC ISO6983 G-code for the fully automatic 5-axis simultaneous machining.
