The Wolff House is a charming example of French Norman architecture with its formidable massing, steeply pitched hipped roof, hipped dormers, and a round tower with a conical roof. A limestone stringcourse marks the division of the brick walls into two stories. Stepped back behind the tower is a low front-facing gable, and false half-timbering and French windows opening onto a small balcony give this gable a medieval appearance. The elliptically arched entrance is sheltered by a buttressed and gabled porch with decorative spindle trusses in the gable end. Heimer of Milwaukee designed the house, and Stengel Construction Company built it.
