For almost three-quarters of a century, as a critic and curator beginning in the 1930s, and as a practicing architect since the 1940s, Philip Johnson has been at the center of modern architecture's development. His celebrated Glass House, built in 1949 in New Canaan, Connecticut - a crystallization of Johnson's commitment to the high modernism of his mentor Mies van der Rohe - is perhaps the single most famous house of the twentieth century. Until now, however, that house has not been looked at in the context of Johnson's many other house projects. This book, the first to comprehensively survey Johnson's residential work, not only brings to light a largely neglected side of Johnson's achievement, but freshly illuminates his entire career.
