The Fisher House, also known as the Norman Fisher House, was designed by the architect Louis Kahn and built for Dr. Norman Fisher and his wife, Doris, a landscape designer, in 1967 in Hatboro, Pennsylvania. Characterized by its dual cubic volumes, stone foundation and detailed cypress cladding, the Fisher house stands as a clear statement of how Kahn was working at the time, and how his work differed from that of his contemporaries. In the Fisher House, Kahn eschews the linearity of the modern plan and focuses on a simple geometry, allowing the cubes to provide a separation of public and private space. Known widely for monumental works like the Salk Institute and the Richards Medical Center, the Fisher house stands as a testament to Kahn’s ability to work with the details of small residential architecture. The Fisher House stands as the clearest example of Kahn's unique architectural style at the time, his use of the two almost perfect cubes differing greatly from much of what was being done at the time and setting him apart in his own field of design.
