Frank Lloyd Wright’s most iconic, and easily most popular home. The house was built partly over a waterfall in Bear Run at Rural Route 1 in the Mill Run section of Stewart Township, Fayette County, Pennsylvania, in the Laurel Highlands of the Allegheny Mountains. For the decades since the public opening of Frank Lloyd Wright’s Fallingwater, the home has been a point of pilgrimage for the famed architect’s fans. Four million people have already visited the home.
This organically designed private residence was intended to be a nature retreat for its owners. The house is well-known for its connection to the site: it is built on top of an active waterfall which flows beneath the house. The fireplace hearth in the living room is composed of boulders found on the site and upon which the house was built — one set of boulders which was left in place protrudes slightly through the living room floor. Wright had initially intended that these boulders would be cut flush with the floor, but this had been one of the Kaufmann family's favorite sunning spots, so Mr. Kaufmann insisted that it be left as it was. The stone floors are waxed, while the hearth is left plain, giving the impression of dry rocks protruding from a stream. Integration with the setting extends even to small details. For example, where glass meets stone walls, there is no metal frame; rather, the glass is caulked directly to the stone. There are stairways directly down to the water. And in the "bridge" that connects the main house to the guest and servant building, a natural boulder drips water inside, which is then directed back out. Bedrooms are small, some even with low ceilings, perhaps to encourage people outward toward the open social areas, decks, and outdoors. The active stream (which can be heard constantly throughout the house), immediate surroundings, and locally quarried stone walls and cantilevered terraces (resembling the nearby rock formations) are meant to be in harmony, in line with Wright's interest in making buildings that were more organic and which thus seemed to be more engaged with their surroundings. Although the waterfall can be heard throughout the house, it can't be seen without going outside. The design incorporates broad expanses of windows and the balconies are off main rooms giving a sense of the closeness of the surroundings. The experiential climax of visiting the house is an interior staircase leading down from the living room allowing direct access to the rushing stream beneath the house-Wiki
