This main element breaks through a thin metal-clad roof surface, emphasizing its lightness as it is supported by slender columns and a latticework of steel beams. High glass walls with delicate frames enclose the hall and the audience areas, giving them a sweeping view of the fjord, the river and the city. In the rising landscape to the west, partially underground, three cinemas are fitted, made of cast concrete, with an art gallery above that opens onto the city. The design is characterized by industrial simplicity. The roof surface is made of lightweight roof elements with their standardized cladding of corrugated iron. The detail work with the steel support structures is standardized. The quay's concrete surface has been retained and brought directly into the foyer areas as polished concrete. The building is intended to be durable, open and stimulating for performers, whether they are amateurs or professionals.
