The PalaisQuartier development in the City of Frankfurt combines restored historical buildings and modern complexes into a huge area for shopping, entertainment and leisure facilities as well as offices and hotels. Waagner-Biro was responsible for the roof and facade structure of building D which contains
a shopping mall and a concert hall. The organic shaped roof is created with a triangular steel lattice and infill panels made of glass and metal panels. The rhombus structured façade part of building D includes a trumpet formed building part which connects the façade and the roof through the building.
