Frank Lloyd Wright's Fallingwater House Completes Major Conservation Project

The Western Pennsylvania Conservancy has announced the conclusion of a three-year conservation program at Fallingwater, the iconic house designed by American architect Frank Lloyd Wright. The project, led by New York-based Architectural Preservation Studio under president Pamela Jerome, addressed long-standing structural issues including water damage, leaks, and material degradation. The house, built in the mid-1930s for Pittsburgh retail magnate Edgar J. Kauffman in Mill Run, Pennsylvania, has faced persistent problems due to original design choices such as the absence of through-wall flashing and the use of river pebbles in concrete, which led to alkali-silica reaction and debonding. The $7 million initiative involved repairing stone walls, sealing joints, replacing windows and doors, and re-waterproofing roofs and terraces. Despite previous conservation efforts, including work by the same studio in 2004, this comprehensive campaign was deemed essential for the preservation of the UNESCO World Heritage Site, which attracts approximately 150,000 annual visitors. The Western Pennsylvania Conservancy has managed the property since its donation by the Kauffman family in 1963. Final touches are scheduled for completion next month, coinciding with the house's 90th anniversary, with documentation of the work to follow. Fallingwater was included in the UNESCO list in 2019 alongside other Wright designs like the Guggenheim Museum.
