Beginning with his earliest encounters with Modernism in the late 1920s and continuing through his iconic work of the 1960s and 1970s, the authors trace the evolution of the architect's thinking, which began and matured through his design of houses and their interiors, a process inspired by his interactions with clients and his admiration for vernacular building traditions. Richly illustrated with new and period photographs and original drawings, as well as previously unpublished materials from personal interviews, archives, and Kahn's own writings, The Houses of Louis Kahn shows how his ideas about domestic spaces challenged conventions, much like his major public commissions, and were developed into one of the most remarkable expressions of the American house.
