The Frank Lloyd Wright House in Ebsworth Park (The Kraus House) was designed by Wright in 1950 at the request of Russell Kraus and his wife Ruth. Located in Kirkwood, Missouri, a suburb of St. Louis, the 1,900-square-foot house is sited in a grassy meadow beside a grove of persimmon trees. The house is an excellent example of Wright’s Usonian architecture, intended to provide middle-class Americans with beautiful design at moderate cost.
For his Usonian homes, Wright developed a “unit system” based on geometric shapes. The Kraus House is based on an equilateral parallelogram with a complex floor plan of intersecting parallelograms. Typical of Usonians, the house has an open living area, a central hearth, concrete slab floors with radiant heat, and a wall of glass doors that affords views of the landscape. The same materials are used both inside and out: brick, concrete, glass, and tidewater red cypress. The doors to the main terrace incorporate stained glass designed by Russell Kraus, a mosaic and stained glass artist.
