Dean of Columbia School of Architecture in New York, Bernard Tschumi has been known since the 1970s as one of architecture's most radical theoreticians and designers, seeking to expand the domain of architectural thinking to embrace ideas from philosophy, psychoanalysis, semiotics, film, literary theory, and art criticism. This book reproduces the most important of his written work over the past 15 years, focused around the concept of space as the common denominator within cities, architecture and social structures.
