Moshe Safdie explains that probably more than half of his lifetime design work is unbuilt, and he considers his unbuilt work to be some of his most significant work. In this richly illustrated book, replete with detailed diagrams, sketches, models and studies, Moshe Safdie explains that for those who design in order to build, not succeeding in building is never a failure (there are many reasons why a project might not be built) because these designs are part of the evolution of an architect's work. This volume is a fascinating journey through Safdie's thoughts and career, and also a historical reference of the social and political forces at play at the time. Not only a treatise on Safdie's unrealized concepts, this book is also a wonderful affirmation that there is valuable heritage in the unbuilt. Includes a number of significant projects from around the globe.
