Adaptive reuse of OSI GThe conversion of the OSI Ghia Factory in Turin – a place of historical importance which, however, was historically left in a state of underutilization – into a new establishment pointing to the modern urban industry can be a way to fill the gap between heritage preservation and current urban development. This study is examining how the transformation of industrial brownfields can give a fresh impetus to the development of sustainable urban areas and at the same time rescue cultural and architectural inheritances. The OSI Ghia Factory, which is a vivid reminder of Turin’s industrial age, offers not only an opportunity but also a challenge in the reopening of a historically valuable and yet forgotten area, which meets the needs of the economy and society in the wake of the renewal of culture and history.
