4.  Kaufmann Residence, a house designed by Wright in 1935 in rural southwestern Pennsylvania.  well-known for its connection to the site: it is built on top of an active waterfall which flows beneath the house.  interpenetrating exterior and interior spaces and a strong emphasis placed on harmony between man and nature.  integration with the setting extends even to small details. Examples: there are stairways leading directly down to the stream, below the house. And in a connecting space which transitions from the main house to the guest and servant level, a natural spring drips water inside, which is then channeled back out. The guest quarters feature a spring-fed swimming pool which overflows to the river below. A glass-encased interior staircase leads down from the living room and allows direct access to the rushing stream below.

During the night, raw (unfiltered) seawater is pumped through exhibits, bringing in food in the form of plankton. Waste ocean water from the aquarium is returned to the Bay.
