Parallel Cities: the Multilevel Metropolis

'Parallel Cities' examines the history of the multilevel city with a focus on elevated pedestrian systems as a recurrent concept in urban planning and design. The book chronicles the evolution and migration of this concept from 19th-century French social utopian thinkers and 20th-century Soviet Constructivist architectural circles to its incubation in postwar London, its theorization by members of CIAM and Team 10, and its eventual dissemination to North America and Asia, where extensive systems were built in cities such as Minneapolis, Calgary and Hong Kong.
