Fallingwater, Edward J. Kauffman Guest House designed by Frank Lloyd Wright, Mill Run, Pennsylvania, 1935

Fallingwater, so named because of its location at the top of a waterfall, illustrates Wright's concept of melding the built and natural environments. The low flat roof and rough cut stones that make up this house cause it to blend to its surroundings, so that it appears as a cliff's edge. Wright attempted to design his buildings so that they enhanced the occupants' enjoyment of the natural landscape. This "organic" architecture made popular by Wright influenced NPS architects who designed buildings in park settings, particularly evident in the low-profile structures at Daingerfield and Tyler State Parks.
