The book covers the entirety of Gowan's work, from his early employment with Powell and Moya and Lyons Israel Ellis through a selection of key projects from his partnership with James Stirling, such as the Leicester Engineering Faculty, 1963. Since then, Gowan has realised 40 years of work under his own name, including the Schreiber House, 1964, one of the most significant houses to be built in Britain in the past century. Following his designs for social housing in the 1960s and 70s the book profiles Gowan's work through to the present day, where at 83 he is completing the Humanitas Hospital in Milan.
