Tadashi Kawamata (born in Japan in 1953, lives and works in Tokyo and Paris) has created in situ art all over the world and was the creative director of the Yokohama Triennale in 2005. His work is concerned with architectural space as a constructed urban or social environment or product. A rigorous examination of the human relationships that define it, as well as the manner of life that comes from them, helps him to gradually identify the nature of his undertaking. His pieces, which are mostly impermanent, are mostly built of wood and sometimes salvaged from the surrounding area.
 
Tadashi Kawamata's works recreate linkages between the past and the present, between the outside and the inside, between the current and the potential: they give the spaces a new identity, stressing the invisible but very real component of its cultural and social character. As we can see from Saint-experience, Thélo's the establishment of a community with which he shares the research and physical effort is the driving force and foundation for each of his undertakings.
