The supporting structure is a cable net system. Dead loads are transferred by vertical cables. Horizontal loads are absorbed by horizontal cable braces. The cable braces consist of two pre-stressed cables stabilized with stainless bracer rods. To compensate possible deformations of the building, the ends of the cables are anchored to the primary structure with springs. The glass panels measure 1.7 x 3.2 m respectively 1.7 m x 1.5 m. They are point supported with stainless steel rotules and spiders.
