After an intensive planning period, the time has come. Today, the official groundbreaking ceremony for the new «Diamant» production building took place. With the new six-story building, which will provide space for 350 workplaces, we continue to commit our attention to the company location in Winterthur. 

This milestone at Kronaustrasse 7 was celebrated alongside the project team, the Strut Architekten, the city president Mike Künzle and all KELLER employees with Winti-Wurst and music.
