It was designed in 1935-1936 and built in four phases between 1937 and 1961.","why_significant":"The nomination argues the house is the first building designed on a hexagonal geometric pattern, using a 120-degree angle throughout, a pattern since used in hundreds of buildings. Wright also planned it to grow and change with the family. It has been praised by critics, plaqued by the AIA as one of seventeen Wright buildings to be retained, and studied by visitors since 1937.","narrative":"Set into the brow of a gently sloping hillside on the Stanford University campus, this one-story redwood, brick and glass house was designed by Frank Lloyd Wright for Paul and Jean Hanna in 1935-1936. Construction began in 1937 and continued in four phases over 25 years, adding a hobby shop, guest house, library, master suite, garden house and pools. Its plan rests on a hexagonal grid with a 120-degree angle, which the nomination describes as the first use of that pattern in a building. Wright conceived the whole project at the outset and designed it so non-bearing walls could be unscrewed and rooms reshaped as the family changed. The AIA plaqued it in 1966 as one of seventeen Wright buildings to be retained, and architects and other visitors have studied it since 1937. The Hannas gave it to Stanford in 1974, and the university planned to use it for a visiting professorship.","period_of_significance":"1900-","architect_builder":"Frank Lloyd Wright","architectural_style":null,"criteria":[],"status_note":"Described in 1977 as in excellent condition and unaltered on its original site; occupied as a private residence, owned by Stanford University after a 1974 gift.
