This is the first book to comprehensively cover the evolution of airport design, from the start of commercial aviation in 1919 to the present day. Many books have been written about airport design at a particular moment in history, but none have rigorously considered why, where, when and how the ideas we now take for granted originated. This book traces the history of airport design considering the philosophies adopted by designers, the functional layouts they have developed and the resultant form of the airport through a series of 40 case studies divided into 7 eras of approximately 20 years each. The themes include: The philosophies underpinning airport design The evolution of design responses How airports have avoided obsolescence Identification of the key turning points The evolution of master plans and terminal concepts in response to increasing traffic volumes The future of airports in terms of environmental sustainability and the Covid-19 hiatus The case studies are international, covering the USA, Germany, the UK, France, the Netherlands, Singapore, Saudi Arabia, Japan, Hong Kong, Malaysia, South Korea, Thailand, Spain, United Arab Emirates, China, Turkey, Mexico, Australia and Poland. They are illustrated with full colour, many of which have not been published before and form part of an incredible graphic package. This book is essential reading for architects, engineers, planners and environmentalists alike.
