Book excerpt: This book presents the best 60 projects of the 2006, 2007, and 2008 Skyscraper Competition. An investigation by architects, students, and designers on the future of the skyscraper. What is the skyscraper in the beginning of the XXI Century? What is the historical and social context of these mega-structures? What is their response towards the urban fabric? Is the modern skyscraper a city in and of itself? Is the human scale lost? Talented architects have entered these competitions to explore, re-think, and speculate on this fascinating architectural genre. Each project includes a full description by the author as well as several illustrations and drawings. In addition, reknown architects were invited to present their thoughts on this fascinating architectural genre.
