Book excerpt: Green roofs, artificial mountains and geological forms; buildings you walk on or over; networks of ramps and warped surfaces; buildings that carve into the ground or landscapes lifted high into the air: all these are commonplace in architecture today. New technologies, new design techniques and a demand for enhanced environmental performance have provoked a re-thinking of architecture's traditional relationship to the ground. The book Landform Building sets out to examine the many manifestations of landscape and ecology in contemporary architectural practice: not as a cross-disciplinary phenomenon (architects working in the landscape) but as new design techniques, new formal strategies and technical problems within architecture.
