Leaks are a given in any Wright house. Indeed, the architect has been notorious not only for his leaks but for his flippant dismissals of client complaints. He reportedly asserted that, “If the roof doesn’t leak, the architect hasn’t been creative enough.” His stock response to clients who complained of leaking roofs was, “That’s how you can tell it’s a roof.”
Wright’s late-in-life triumph, Fallingwater in Pennsylvania, celebrated by the AIA poll as “the best all-time work of American architecture,” lives up to its name with a plague of leaks; they have marred the windows and stone walls and deteriorated the structural concrete. To its original owner, Fallingwater was known as “Rising Mildew,” a “seven-bucket building.” It is indeed a gorgeous and influential house, but unlivable. For its leaks there can be no excuse.
