Statement of Significance (as of designation - May 11, 1976):
A summer house built for a Pittsburgh millionaire, Fallingwater (1937) has been called the most famous modern house in the world. The house, cantilevered over a waterfall, is one of Frank Lloyd Wright's masterworks.

Condition:
Parts of the house are overstressed and are beginning to fail. Water leakage is damaging the roof and interior furnishings.

The Living Room cantilevers were successfully strengthened in March 2002. Strengthening of the main floor cantilever is clearly a dramatic aspect of the building’s restoration; however there are many other vital components that were repaired or restored that will ensure the long-term preservation of this National Historic Landmark. They include: *Installation of an expansion joint where the canopy meets the guest house * Restoration and repair of the corroded, and in some locations inoperable, steel sash that comprises the framing of the windows and doors throughout the building. * Conservation of all interior built-in and free standing Frank Lloyd Wright-designed furniture and woodwork that has been damaged by ultraviolet light, high humidity and water penetration over the past 60+ years * Restoration of the badly corroded steel supports and spalled concrete treads of the stairs that connect the living room to the stream. * Waterproofing/roofing of all terraces and flat roofs to properly shed water. * Cleaning and repointing the exterior stone walls * Structural strengthening of Edgar Kaufmann Sr.’s cantilevered terrace with carbon fiber.
