Sir Denys Lasdun is one of Britain´s most eminent living architects, whose career spans the entire period of Modernism in British architecture. His notable buildings include the Royal College of Physicians in Regent´s Park, the University of East Anglia, the European Investment Bank in Luxembourg and the National Theatre on London´s South Bank. In this first full-length study of the architect, William Curtis offers a critical assessment of Lasdun´s ideas and achievements, tracing the evolution of his architectural language and his continuing preoccupations. With detailed analyses and many outstanding illustrations from the architect´s own archive, the author presents a challenge to the critics of Modernism and demonstrates the enduring and human qualities of Lasdun´s work.
