The Farnsworth House was designed and constructed by Ludwig Mies van der Rohe between 1945 and 1951. It is a one-room weekend retreat in a once-rural setting, located 55 miles (89 km) southwest of Chicago's downtown on a 60-acre (24 ha) estate site, adjoining the Fox River, south of the city of Plano, Illinois. Mies created a 1,500-square-foot (140 m2) house that is widely recognized as an iconic masterpiece of International Style of architecture.
