From the architect. The Farnsworth House, built between 1945 and 1951 for Dr. Edith Farnsworth as a weekend retreat, is a platonic perfection of order gently placed in spontaneous nature in Plano, Illinois. Just right outside of Chicago 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.
