The former Tonhallen site in the small town of Villingen-Schwenningen in the Black Forest has lain empty for 20 years. The authorities expect this new development to both revitalize the town center and create a significant architectural bridge between the old town and the banks of the River Brigach. The decision-makers in the urban planning development process were convinced by the concept submitted by ATP Munich and the project developer S&P Commercial Development GmbH, a company of the Sontowski & Partner Group.
