On Zelgstrasse in Uster, the client UBS Sima is building a pioneering residential quarter with a clear focus on environmentally conscious and future-oriented system construction. Originally planned as a conventional construction project with 164 apartments, it developed into a flagship project for sustainable, fast and low-emission construction - with minimal noise and traffic pollution - thanks to an innovative competition process. With the help of the TS3 system, the residential development is being built in the shortest possible time.
