Fallingwater is a vacation home designed by the American architect Frank Lloyd Wright. Wright was commissioned for the project by Edgar Kaufmann, owner of Kaufmann's Department Store in Pittsburgh. It was completed in 1939.
The house is an excellent example of several architectural principles embodied in the work of Wright, including dominant horizontal lines, low- ceiling interior space and strong integration with the landscape. It is perhaps best known for its concrete cantilevered construction which allows it to sit directly above a waterfall on Bear Run, a creek in the Laurel Highlands area of southwestern Pennsylvania.
