"The building consists of one horizontally directed spiral whose ends are interwoven with its middle part to generate the internal organisation. Differentiating the spiral allows for creating buffer zones between the functions as well as fulfilling the different spatial needs of the various programme parts. The spiral organisation allows for transition zones, offering acoustic buffering as well as forming a secondary routing system which gives the performers a side path, connecting the internal, private functions. Central in the concept of the building is the large room that can be flexibly used as working place, concert room and music theatre. Attached to this central room are a cafetaria, technical spaces and dressing rooms"
