Performers' dressing rooms can be found on the ground floor and there is a staff room in the mezzanine behind the big hall. Rooms for production, sound engineering, interpreters and administration are all in the attic. Likewise, there is storage space for instruments in the basement. All of these rooms are accessible via staircases and elevators that are not connected to the public space. Event organizers can enter the inner courtyard via Sedanstraße and access the stage on ground level through the back wall of the main hall.
