Fallingwater
Fallingwater is a weekend retreat built over a 20-foot waterfall on Bear Run in Stewart Township, southwestern Pennsylvania. Designed by Frank Lloyd Wright for Edgar J. Kaufmann Sr. and Liliane Kaufmann, it uses exposed cantilevers, sandstone verticals, and concrete horizontals. Its 30° counterclockwise orientation ensures natural light in all rooms. Wright insisted occupants live *with* the waterfall — not look at it — using identical materials inside and out to dissolve boundaries. Trees were preserved via adaptive detailing. The design was judged unsound by Kaufmann’s engineers; the contractor secretly reinforced concrete elements. Structural vulnerabilities confirmed in 1994 led to steel supports and post-tensioning by 2002. At $155,000, it was one of Wright’s most expensive commissions.
