The home that Frank Lloyd Wright built in Phoenix, Arizona, for his son and daughter-in-law was just purchased by an anonymous buyer and will be transferred to an Arizona nonprofit organization. The house, which was erected between 1950 and 1952, was  sold to developers and was facing the possibility of being demolished for future development projects.

The Frank Lloyd Wright Building Conservancy petitioned the city to help protect the property as a landmark and collected more than 28,000 signatures in support of its preservation. Built six years before the Guggenheim, the structure is the only residence that features a similar circular floorplan.

"This purchase is a magnificent and generous action," said Larry Woodin, president of the conservancy. "It is a gift to the people of Phoenix, a gift to the worldwide architectural community and to everyone that cares about the history of modern architecture."

The Phoenix Business Journal reports that the house was sold for more than $2.38 million by an individual who preferred to remain anonymous.

Individuals, programs and organizations that provide large gifts to organizations might find nonprofit fundraising software advantageous to help contributors manage their donations.
