This project was our contribution to a limited competition of the city of Heidelberg in 2008. The task was to renovate and to supplement the main building of the city's theater and philharmonic orchestra, taking into account several listed buildings. In addition to the refurbishment, the focus of the bid task was the optimization of the functional processes, the economic and energetic efficiency and the integration of the new parts in the urban context of the historic old town. The complex relationship between reality and imagination was the focus of our idea. The concept was to integrate the new theater spatially as a theater of the people in the city.
