A modern office building with a timeless appearance, characterized by contemporary functionality. The gallery façade made of aluminium and glass with integrated solar shading is the old and new visual highlight of the building, which is characterized by volume flow controllers and ventilation sashes that can be operated manually via the window handles. Ventilated glass cladding and an all-glass vestibule at the entrance ensure optimum energy savings. The large louvre façade also conceals state-of-the-art thermal insulation glazing. Barrier-free and convenient access is provided by automatic sliding doors.
