A steel grid, made of built-up sections consisting of flat steel bars, and supported on four columns, serves as the supporting structure of the roof; the coffered grid extends beyond the column axes on all sides. The four frame columns, which are fixed at the bottom and in the grillage at the top, allow for vertical load transfer and provide stability to the structure. At the roof edges, the suspended vertical steel elements supporting the facades are rigidly connected to the cantilever beams of the roof. The roof cladding consists of square glass panels directly attached to the steel elements. Each façade glass panel is supported by four stainless steel brackets and shingled both horizontally and vertically..
