The new Spuiforum brings together a 1500 seat concert hall, a 1300 seat dance/opera hall and a 600 seat ensemble hall. The halls are stacked on top of each other and imbedded in a flexible structure of educational classrooms and studios for the Royal Conservatory. The heart of the complex is shaped as a monumental mountain of stairs, that brings visitors all the way up to the public roof that overlooks the city. The building is crowned with a large cupola hall for all kinds of public events. The filigrain exo-skeleton gives the façade a refined and festive expression.
