An international survey of projects completed during the 1990s using high-tech forms and materials for environmentally intelligent means. Bringing together approaches by established practitioners - Richard Rogers, Norman Foster, Nicholas Grimshaw and Michael Hopkins - with a new generation of architects - Thomas Herzog, Von Gerkan Marg, Design Antenna and Future Systems - this book presents their examples in detailed form. The introduction charts the evolution of high-tech architecture and its progression toward more ecological concerns, while the movement as a whole is considered in a broader architectural context. At the heart of the book is a selection of 40 of the world's most sophisticated projects, each with a description of its unique architectural and technological features, as well as extensive plans, drawings and sketches. The reference section includes biographies and technical details of each project.
