On Zelgstrasse in Uster, the developer UBS Sima is creating a pioneering residential neighborhood with a clear focus on environmentally conscious and forward-looking modular construction. Originally planned as a conventional construction project with 164 apartments, it evolved—thanks to an innovative competitive design process—into a flagship project for sustainable, rapid, and low-emission construction—with minimal noise and traffic impact. With the help of the TS3 system, the residential complex is being built in record time.
