Louis I. Kahn (1901-74) was one of the single greatest influences on world architecture in the second half of the twentieth century. This book provides a comprehensive critical overview of Kahn's architecture, examining his works chronologically and exploring key themes and their evolution throughout his career. Including both built and unbuilt projects, each of the architect's major buildings is analysed, beginning with the design process and ordering ideas, followed by the methods and materials of construction, and finally a 'walk-through' of the spaces themselves - recognizing that Kahn's primary concern was interior space and its experience. Each project is extensively illustrated with photographs that convey the spirit of Kahn's work and a concept development portfolio documents the inspirations and ideas that led to the finished design.Robert McCarter's authoritative text explores how Louis I. Kahn redefined modern architecture. Featuring a selection of original drawings and photographs from the Louis I. Kahn Archives and newly redrawn plans, this book also includes selected writings by Kahn and the first publication of the complete chronology of Kahn's buildings and projects, compiled by William Whitaker, Chief Curator of the Louis I. Kahn Archives. This monograph is an indispensable reference work on this renowned architect.
