Falling Water Villa, located on a waterfall on a rocky hillside deep in a rugged forest in southwestern Pennsylvania, about 90 minutes from Pittsburgh, is one of the most famous houses in America. For American architect Frank Lloyd Wright, the design of Fallingwater was a personal milestone, as it clearly marked a turning point in his career. After this late career triumph, Frank Lloyd Wright went on to create a series of highly original designs that validated his claim to be "the world's greatest architect".

Fallingwater consists of two parts: The main house of the clients which was built between 1936-1938, and the guest room which was completed in 1939. The original house contains simple rooms furnished by Wright himself, with an open living room and compact kitchen on the first floor, and three small bedrooms located on the second floor. The third floor was the location of the study and bedroom of Edgar Jr., the Kaufmann's son.The rooms all relate towards the house's natural surroundings, and the living room even has steps that lead directly into the water below. 

The circulation through the house consists of dark, narrow passageways, intended this way so that people experience a feeling of compression when compared to that of expansion the closer they get to the outdoors. The ceilings of the rooms are low, reaching only up to 6'4" in some places, in order to direct the eye horizontally to look outside. 

The beauty of these spaces is found in their extensions towards nature, done with long cantilevered terraces. Shooting out at a series of right angles, the terraces add an element of sculpture to the houses aside from their function.The terraces form a complex, overriding horizontal force with their protrusions that liberated space with their risen planes parallel to the ground.
