Designed in 1935 by Frank Lloyd Wright, Fallingwater or Kaufmann Residence is one the famous architect’s most recognizable works. Located in rural southwestern Pennsylvania, about 43 miles (69 km) southeast of Pittsburgh, Fallingwater is constructed over a waterfall on Bear Run river. The house was designed as a weekend home for the family of Liliane Kaufmann and her husband, Edgar J. Kaufmann, owner of Kaufmann’s department store. [source]

Time cited it after its completion as Wright’s “most beautiful job”; it is listed among Smithsonian’s Life List of 28 places “to visit before you die”. It was designated a National Historic Landmark in 1966. In 1991, members of the American Institute of Architects named the house the “best all-time work of American architecture” and in 2007, it was ranked 29th on the list of America’s Favorite Architecture according to the AIA.
