Wright adapted his Usonian plan to a steep site in this 2,350-square-foot house. It is T-shaped, with the entrance at the crossing. Access to the main living area is through a sky-lit loggia with an open well to a lower-level garden and stream. The functions of living, dining and work rooms are consolidated in a unified space that spans a 40-foot ravine. A balcony wraps two sides of the cantilevered living room. The bedroom wing anchors the house to the hill. At the center an atrium looks down on a reflecting pool and pulls up cool air for natural air conditioning. The Afflecks’ children donated the house in 1978 to Lawrence Technological University, which has undertaken its restoration.
