This book focuses on the spaces of production in cities that both comprise factories that are significant in their design and contribute to a vital urban environment. This book re-examines the historic modernist and contemporary factories through the lens of an urbanist while provoking the future of urban manufacturing. It shows that now factories are cleaner and greener and they can be reintegrated in city life creating a new paradigm for sustainable urban industry that is also more self-sufficient. Illustrated with historic and contemporary photographs and manufacturing process diagrams.
