It is a wood-frame, stucco-surfaced residence in the Prairie School style, with strong horizontal emphasis, banded windows, overhanging eaves, accentuated piers, a hidden doorway and a string course below the second-story window ribbons. The plan is a symmetrical modified cruciform with multiple levels, built-in furnishings and an open layout, and it has no applied ornament. It was conceived as a $3,500 economy house. The house is one of three Wright designed in Highland Park and one of his early Prairie houses. Its plan follows the modified cruciform type established in the Ward W. Willits House of 1902 and later used in the Robie House of 1909. It represents a key period in Wright's career and retains its original hardware. Its condition is listed as deteriorated, and some art or leaded glass windows have been removed.
