The stage set model for Hoffmann consisted of a ball of modeling clay and a piece of cardboard, which was already slightly curved. Only gradually did it become clear what technical challenges would be hidden in it.

The 8.6m x 8.6m platform stands in an otherwise almost empty black room. In the middle with a height of 1.6m, the level can be tilted in all directions. A continuous accessibility with the usual traffic loads and the movement with 60 people leads to a construction that leaves the usual construction method of the Komische Oper far behind.

In order to take into account the set-up times in repertoire operations and the safety aspects, all movement-relevant components were brought together in a core element. The construction in the form of a cardan joint, which is driven in the two axes by two hydraulic cylinders each, enables movements in all directions when superimposed.

Due to the load assumptions and the geometry, correspondingly powerful cylinders were used. The specially purchased hydraulic unit was in the basement, and the hose lines were permanently installed in the building.

The weight of 4 t for the core and a total weight of the platform of approx. 8 t as well as approx. 4 t person load on the four positions of the core element were loaded with construction spindles via the turntable onto the foundation in the lower stage. Four lifting units with tilting towers and commercially available jacks were installed in the construction for moving. Special transport vehicles were designed to transport and attach the heavy booms.

Each axis was operated by a technician with a joystick, the four additional dead man's switches distributed in the corners of the stage provided comprehensive supervision and safe operation. An infrared camera and a hand-painted scale were used to monitor the pitch, which in practice was quite sufficient for the magical and musical movements.
