Guy Rottier is the man behind a mulitfaceted, unclassifiable body of work in which art and architecture, poetry and technology, are in constant interaction. Dazzlingly uncompromising, Rottier set out to radically renew both the language of architecture and the disciple's standardised lifestyles. Mischievous, whimsical and free-spirted, he stood out all this life for an architecture more playful than entertaining, more childlike, breaking all the rules from traditionto the law of gravity so as to redynamise asclerotically ordered world. This catalogue retraces the career and the major projects of one of the most original "artchitects" of the second half of the 20th century.
