It is impossible to understand the architecture of the twentieth century and of our own time without first coming to terms with Le Corbusier (1887–1965). His buildings can be found from Paris to La Plata to the Punjab and his influence has extended over several generations worldwide. Individual masterpieces such as the Villa Savoye at Poissy, the Chapel of Notre Dame-du-Haut at Ronchamp and the Parliament Building in Chandigarh, bear comparison with the works of any age. As well as an architect, Le Corbusier was also a painter, sculptor, urbanist and author; even a philosopher who ruminated upon the human condition in the modern era. He reordered the ground rules of the architectural discipline and invested his insights with a universal tone. This probing study of Le Corbusier’s work explores the interactions of ideas and forms in his individual buildings and in his oeuvre as a whole. By penetrating the design processes of his major buildings it reveals the architect’s struggle to reconcile the ideal and the practical and to give clients’ aspirations and society’s institutions a suitable symbolic form.
