Hanna House by Frank Lloyd Wright

Hanna House was designed by Frank Lloyd Wright in 1936 for Stanford Professor Paul Hanna and his wife, Jean, specialists in childhood education. Wright had become interested in designing elegant and affordable homes for the American middle class to create a more harmonious, enlightened society. The long-term collaboration between the Hannas and Wright resulted in an unprecedented design: a house based on hexagonal geometry, with no right angles in the floor plan. This radical experimentation allowed Wright to explore open spatial planning. Hanna House was a turning point in his career, leading to ideas later evidenced in the Guggenheim Museum in New York.
