Designed in 1957, it is the first of the only two examples of the second type (known as Prefab #2) of the Marshall Erdman Prefab Houses. This house and the James McBean Residence have the same floor plan and vary only in minor details such as paint color and siting. Construction was completed in June, 1959 and the house was sold to UW-Madison mathematicians Walter and Mary Ellen Rudin.
