This book draws together classic and contemporary texts on the "Horizontal Metropolis" concept. Taking an interdisciplinary approach, it explores various theoretical, methodological and political implications of the Horizontal Metropolis hypothesis. Assembling a series of textual and cartographic interventions, this book explores those that supersede inherited spatial ontologies (urban/rural, town/country, city/non-city, society/nature). It investigates the emergence of a new type of extended urbanity across regions, territories and continents up to the global scale through the reconstruction of a fundamental but neglected tradition. This book responds to the radical nature of the changes underway today, calling for a rethinking of the Western Metropolis idea and form along with the emergence of new urban paradigms. The Horizontal Metropolis concept represents an ambitious attempt to offer new instruction to take on this challenge at the global scale. The book is intended fora wide audience interested in the emergence and development of new approaches in urbanism, architecture, cultural theory, urban and design education, landscape urbanism and geography.
