Built in 1903 in downtown Madison, the Robert M. Lamp House is the oldest Frank Lloyd Wright-designed house in the city and an important early work between the Chicago School and the emerging Prairie School. Created for Wright’s lifelong friend Robert M. Lamp, the house occupies a secluded mid-block keyhole lot approached by a narrow driveway, with the steep site shaped into terraces and layered gardens. Its modern boxy form, hidden entry, and open interior plan centered on a large living room anticipated ideas that became highly influential in Wright’s later houses and in Prairie School domestic architecture. It was listed on the National Register of Historic Places in 1978.
