This unique visual history documents in pictures the most exciting and dynamic period of architecture: from the early 20th century to the present day, covering all the key movements, styles and architects, together with many lesser known but important names and buildings. Through archival and full-colour photography, plans and architectural drawings, the book illustrates the changing nature of architecture and its expansion during this period from the early developments of concrete and the steel frame, through national styles of architecture and the eruption of Modernism to the influence of science and engineering in the post-war period, the provocative arguments of Postmodernism in the 1980s, right up to today's superstars and global brands.
