Philip Drew is a Sydney based architectural critic who studied architecture at UNSW (B Arch) and has a Masters degree from Sydney University. He has travelled extensively in Japan, North America and Europe and is the author of 22 books including monographs on Frei Otto, Arata Isozaki, Glenn Murcutt, Peter Stutchbury and the Barcelona firm of MBM. His interests encompass nomadic buildings, specifically nomad tents and urban tents, lightweight architecture, vernacular buildings, and the Australian veranda and interest which flowed from his classic study of Glenn Murcutt's development of a new type of contemporary veranda-house. He was contributed extensively to international architectural encyclopedias and dictionaries and more than 340 articles and papers on design. His latest book is a critical evaluation of Joern Utzon and his Sydney Opera House which discusses the typology of opera houses which analyses how Utzon's departure from the conventional arrangement of foyer, auditorium, stage and back stage areas by inserting the stage between foyer and auditorium has imposed insuperable problems, past and future, for its long term operation. Philip Drew is a contributor to Indesign, Habitus, Architectural Review and Monument.
