Staatstheater am Gärtnerplatz, Munich, Germany

The Staatstheater am Gärtnerplatz is a listed building in the centre of Munich. In the course of a general renovation, the foyer, auditorium and stage were refurbished and a new extension for rehearsal rooms and administration was built.

To make the new building possible on the completely overbuilt site, several underground floors were necessary, which were built in a watertight building pit enclosure more than 10 m deep. During the extensive work in the excavation pit, the stability of the directly adjacent residential buildings, as well as the listed façade, had to be guaranteed at all times, and the complete functional preservation of the historic stage had to be maintained.
