The house is in Fort Washington, Pennsylvania, a section of Whitemarsh Township approximately twenty miles from downtown Philadelphia. William Whitaker, curator of the University of Pennsylvania’s Architectural Archives and co-author of The Houses of Louis Kahn, points out that in all of his residential projects, Kahn was sensitive to the history of a place, choice of materials, and how to situate a house within its landscape.1 Fort Washington represented a specific historical context as well as an opportunity to think about the future. Estate farms and pastureland mark the landscape, reminders of the region’s past. Also “formative to Kahn’s approach” was the nearby William Stix Wasserman House (1932), a modernist country home designed by William Lescaze and George Howe, Kahn’s colleague and former partner.
