Fallingwater

Fallingwater is a house museum in Stewart Township in the Laurel Highlands of southwestern Pennsylvania, United States. Designed by the architect Frank Lloyd Wright, it is built partly over a waterfall on the Bear Run stream. The three-story residence was developed as a weekend retreat for Edgar J. Kaufmann Sr., the owner of Kaufmann's Department Store in Pittsburgh, and his wife Liliane. The Western Pennsylvania Conservancy (WPC), which has operated Fallingwater as a tourist attraction since 1963, maintains 5,000 acres (2,000 ha) surrounding the house.

Edgar Kaufmann Sr. had established a summer retreat at Bear Run for his employees by 1916. When employees stopped using the retreat, the Kaufmanns bought the site in July 1933 and hired Wright to design the house in 1934. Several structural issues arose during the house's construction, including cracked concrete and sagging terraces. The Kaufmanns began using the house in 1937 and hired Wright to design a guest wing, which was finished in 1939. Edgar Kaufmann Jr., the Kaufmanns' son, continued to use the house after his parents' deaths. After the WPC took over, it began hosting tours of the house in July 1964 and built a visitor center in 1979. The house was renovated in the late 1990s and early 2000s to remedy severe structural defects, including sagging terraces and poor drainage.
