The Farnsworth House built for Dr. Edith Farnsworth as a weekend retreat, is a platonic perfection of order gently placed in spontaneous nature in Plano, Illinois. Situated in a 10-acre secluded wooded site with the Fox River to the south, the glass pavilion takes full advantage of relating to its natural surroundings, achieving Mies' concept of a strong relationship between the house and nature. The single-story house consists of eight I-shaped steel columns that support the roof and floor frameworks, and therefore are both structural and expressive. In between these columns are floor-to-ceiling windows around the entire house, opening up the rooms to the woods around it. The windows are what provide the beauty of Mies' idea of tying the residence with its tranquil surroundings. His idea for shading and privacy was through the many trees that were located on the private site.
