What iconic Wright building was built over a waterfall?

Fallingwater is the iconic Frank Lloyd Wright building built over a waterfall. Designed in 1935 for Pittsburgh department-store owner Edgar J. Kaufmann and his family, the house stands above Bear Run in Pennsylvania’s Laurel Highlands.

Wright positioned the main house directly over the stream and waterfall rather than placing it downstream, where the Kaufmanns had initially expected to build. His goal was to make the family live with the waterfall, hearing and experiencing it as part of daily life rather than merely viewing it from a distance.

The house is celebrated for its cantilevered reinforced-concrete terraces, local sandstone, broad windows, and organic relationship with the landscape. Construction of the main house took place in 1936–1937, with a guest wing completed in 1939. Fallingwater is sometimes mistakenly confused with Taliesin, Wright’s Wisconsin home and studio, or the Guggenheim Museum, his New York museum.
