a Chicago architect Palumbo commissioned specifically for the house. In 2001, Palumbo struck a deal with the state of Illinois, which agreed to buy the house for $7 million and open it full-time to the public, but state officials withdrew from the deal in early 2003, saying $7 million was too much to spend at a time of financial crisis. After owning the property for 31 years, Palumbo removed the art and put the property up for sale with Sotheby's in 2003, raising serious concerns about the future of the building. Preservationists and contributors from around the world, including the Friends of the Farnsworth House, began a concerted preservation and fund-raising effort to keep the house on its original site. With this financial support, the National Trust for Historic Preservation and Landmarks Illinois were able to purchase the house in December 2003 for a reported $7.5 million. Now operated as a house museum, the Farnsworth House is open to the public, with tours conducted by the National Trust. The house is listed in the National Register and is designated a National Historic Landmark by the United States Department of the Interior. Configuration The essential characteristics of the house are immediately apparent. The extensive use of clear floor-to-ceiling glass opens the interior to its natural surroundings to an extreme degree. Two distinctly expressed horizontal slabs, which form the roof and the floor, sandwich an open space for living. The slab edges are defined by exposed steel structural members painted pure white. The house is elevated above a flood plain by eight wide flange steel columns which are attached to the sides of the floor and ceiling slabs. The slab ends extend beyond the column supports, creating cantilevers. A third floating slab, an attached terrace, acts as a transition between the living area and the ground. The house is accessed by two sets of wide steps connecting ground to terrace and then to porch. Mies found the large open exhibit halls of the turn of the century to be very much in character with his sense of the industrial era. Here he applied the concept of an unobstructed space that is flexible for use by people. The interior appears to be a single open room, its space ebbing and flowing around two wood blocks; one a wardrobe cabinet and the other containing a kitchen, toilet, and fireplace block (the "core").
