A vast dome covering part of Manhattan in a diaphanous skin; Frank Lloyd Wright’s mile-high skyscraper; a 19th-century ‘Gothic’ cathedral; or Vladimir Tatlin’s design for a stupendous monument to the Third International ... Some of the most exciting buildings in the history of architecture were never constructed, yet the plans survive. Illustrated with reproductions of architectural drawings, paintings and prints, this book surveys 50 abandoned schemes including ideal cities, eccentricities such as The Triumphal Elephant, and more recent green experiments.
