Peter Cook's distinctive drawings have captivated and inspired generations of designers. Freed from stylistic or functional conventions, his graphic speculations have redefined the language of architectural communication. Speculations spans Cook's entire career, presenting some 160 drawings that range from student projects in the 1950s, through Archigram, to new work completed shortly before going to press. Arranged chronologically, these drawings chart the course of what can now be seen as an enthralling architectural adventure. Cook's own observations about the nature of architecture and urbanism, and the concept of the buildable, are complemented by pieces from architects Frank Gehry, Toyo Ito, Thom Mayne and Peter Wilson.
