It has been a tremendous satisfaction to compile this book about the past, present, and future of the skyscraper. No other architectural genre captures our imagination and reflects our cultural and technological achievements like these towers that pierce the sky. We start off with the history and evolution of building high, from the Egyptian pyramids, Gothic cathedrals, and first American skyscrapers to the contemporary reality in Asia and the Middle East. We present two fascinating interviews, the first one with Carol Willis, the founder and director of the Skyscraper Museum in New York City, who explains the true genetics and economics behind the birth and future of the skyscraper. The second one with Italian artist, Giacomo Costa, who shares his vision about the relationship between the natural environment, human activity, and supernatural reality with provocative images of an apocalyptic urban future. Javier Quintana exposes the time gap between new architectural concepts and their built reality like Arne Hosek s City of the Future designed in 1928 and materialized in 1998 by César Pelli as the Petronas Towers in Kuala Lumpur or Sergei Lopatin s 1925 idea for the Veshenka Tower in Moscow, later observed as the Willis Tower (former Sears Tower) in Chicago in 1974. Another group of essays explore the global influence of Manhattan as a contemporary Babylon to be replicated across the world, or the role of the Italian Futurists, Japanese Metabolists, and Archigram, who influenced generations of architects and designers to push forward the concept of vertical living. In the Opinion section you will find critiques on some of the latest ideas for skyscraper design by some of the most forward-looking architects like the concept of pixilated tectonics in Le Project Triangle in Paris by Herzog & de Meuron and Rodøvere s Sky Village by MVRDV. On the other hand, Jean Nouvel redefined the Italian loggia towers of the seventeenth century with the Tour Signal in La Défense, Paris; while Morphosis Architects explores new programs for vertical density with The Phare Tower. Lastly, Studio SHIFT masterfully integrates their Miyi Tower in Sichuan, China, with the existing landscape. Central to this book are thirty projects from eVolo s 2009 Skyscraper Competition which look into the future of the skyscraper with the use of new technologies, programs, and aesthetic expression. Sustainability, globalization, flexibility, and adaptability are just some of the multi-layered elements explored by some the entries. You will find examples of cities in the sky, horizontal skyscrapers that link various cities, or emergency architecture for disaster zones. Finally, we present the work of Aranda / Lasch, a young New York-based design studio which develops their research on the observation of the patterns of organization in the natural world and its implementation in architecture and design. Their Quasi-Series furniture is designed following the assemblage logic of Quasi-crystals, where a structural pattern does not repeat itself.
