Since 2011, the Swiss city of St. Gallen’s public hospital KSSG–OKS has been undergoing a comprehensive rebuilding and extension program. Developed by Zurich-based firm Fawad Kazi Architekt in collaboration with the KSSG–OKS planning consortium, the vast undertaking will completely transform the site into a large, coherent building complex by 2029.This third volume of the eventually five-part monograph on this major and hugely demanding urban development project is dedicated to Haus 07A, the largest of the new buildings, which gives the entire complex a new urban face. A high-rise that mainly hosts the hospital’s wards is founded on a three-story elongated base with a spacious public roof terrace and including also the main entrance to the entire hospital complex.Text in English and German.
