Like a cloth draped over seven spheres – that’s the image that the impressive steel and glass architecture conjures up in viewers of the multi-functional building in the heart of Warsaw. At approximately 10,000 m², the geometrically complex gridshell is a huge free-form surface. Triangular glass panels give the greatest possible flexibility to form the curvature. For the design of the steel nodes, Waagner-Biro developed the technology already used to construct the roof of the Great Court at the British Museum. Using this innovative technology created an architectural landmark whose elegance is unique throughout the country. It deservedly won the European Steel Design Award 2007.
