In the Spring of 2006 I got the opportunity to visit. One element that isn't featured most texts is that the home is placed on the north side of a hugh Maple tree that shades the entire residence.
The Farnsworth House, designed and constructed by Ludwig Mies van der Rohe between 1945-51, is a one-room weekend retreat in a once-rural setting, located 55 miles southwest of Chicago's downtown on a 60 acre estate site adjoining the Fox River (Illinois) south of the city of Plano, Illinois. The steel and glass house was commissioned by Dr. Edith Farnsworth, a prominent Chicago-based kidney specialist, as a place where she could enjoy nature and engage in her hobbies, playing the violin, translating poetry, and enjoying nature. Mies created for her a 1,500 square foot house that is widely recognized as an iconic masterpiece of modernist architecture. The home was designated a National Historic Landmark in 2006.
