Fallingwater stands as one of Wright’s greatest masterpieces both for its dynamism and for its integration with the striking natural surroundings. Fallingwater has been described as an architectural tour de force of Wright’s organic philosophy. Wright’s passion for Japanese architecture was strongly reflected in the design of Fallingwater, particularly in the importance of interpenetrating exterior and interior spaces and the strong emphasis placed on harmony between man and nature. Contemporary Japanese architect Tadao Ando has stated: “I think Wright learned the most important aspect of architecture, the treatment of space, from Japanese architecture. When I visited Fallingwater in Pennsylvania, I found that same sensibility of space.”
Fallingwater or Kaufmann Residence is a house designed by architect Frank Lloyd Wright in 1935 in rural southwestern Pennsylvania, 43 miles (69 km) southeast of Pittsburgh.
The construction was plagued by conflicts between Wright, Kaufmann, and the construction contractor. Uncomfortable with what he saw as Wright’s insufficient experience using reinforced concrete, Kaufmann had the architect’s daring cantilever design reviewed by a firm of consulting engineers.
