The Hanna–Honeycomb House, also known as simply the Hanna House, located on the Stanford University campus in Stanford, California, United States, was Frank Lloyd Wright's first work in the Bay Area and his first work with non-rectangular structures. The house was chosen by the American Institute of Architects as one of seventeen buildings by the architect to be retained as an example of his contribution to American culture. It was recognized as a National Historic Landmark on June 29, 1989. Name The Hanna house, maintained by Stanford University, is called Honeycomb House because the Usonian structure's plan is fashioned on a hexagonal unit system, a module that replaced the octagon as Wright's favorite from this time on. — William Allin Storrer Design Begun in 1937 and expanded over 25 years, this is the first and best example of Wright's innovative hexagonal design. A Usonian home patterned after the honeycomb of a bee, the 3,570 square foot house incorporates six-sided figures with 120-degree angles in its plan, in its numerous tiled terraces, and even in built-in furnishings. In American National Bibliography Frederick Ivor-Campbell wrote "(the) Honeycomb House showed how Wright's system of Polygonal modules could provide the openness that he associated with freedom of movement while gracefully integrating the house with its sloping topography. The hexagonal modules of the floor plan gave the appearance of a honeycomb; hence the name of the house." There are no right angles on the floor plan. The Hanna-Honeycomb house was designed for Professor Paul Robert Hanna (1902-1988), and his wife, Jean Shuman Hanna (1902-1987), both well-known educators and for many years associated with Stanford University. The project was begun while they were a young married couple with three children. The home thus had four bedrooms and three bathrooms. In the years following the departure of the children, the house was expanded and modified (with Wright's assistance) as the professional and personal needs of the Hannas changed. Construction and restoration The construction process was not without difficulty. Wright's initial plans called for flat terrain, but the lot the Hannas purchased was hilly. Cost overruns meant that the original $15,000 price tag ballooned to over $37,000 ($ adjusted for inflation). Additionally, the Hannas discovered that their lot encompassed a portion of the San Andreas Fault. Wright, whose Imperial Hotel had survived the 1923 Great Kantō earthquake, was undaunted. Unfortunately, the home was severely damaged by the 1989
