Shigeru Ban (Tokyo, 1957) is a Japanese architect, who studied in the United States (Southern California Institute of Architecture, 1980, and Cooper Union School of Architecture, 1984). This monograph study is centred on a series of projects which explore the possibilities of unconventional materials such as PTS (Paper Tube Structure). The work of Shigeru Ban posits the search for a personal path, always pioneering and deeply committed, in which experimentation provides the response to real architectural problems, as in the case of the shelters for those made homeless by disasters in Kobe or Rwanda.
