Fallingwater is one of Frank Lloyd Wright's masterpieces, but in the 1936 letter he threatened to walk off the job four months after work began.<br /><br />Fallingwater, a National Historic Landmark about 65 miles southeast of Pittsburgh, was built over a waterfall. Wright was paid $8,000 in architect fees for the job, and construction was completed in 1938, according to the Fallingwater website. Hall, the lead contractor, was paid $50 per week.<br /><br />The home was commissioned as a country retreat by the Edgar J. Kaufmann family of Pittsburgh, owners of Kaufmann's Department Store. The modern design, nestled into a rock mountainside, attracted immediate attention and was featured on the cover of Time magazine in 1938.<br /><br />The letter and an original blueprint of the house are being sold by RR Auction of Amherst, N.H.
