The Hostess House was designed by famed architect Julia Morgan, the first woman to become a certified architect in the state of California. The building was constructed in the Craftsman style, and includes a number of trademark Morgan elements, such as the use of wooden beams.
After the war, all the buildings were torn down at the camps and the lumber sold. The city of Palo Alto purchased the house and moved it to its current location. There, it became the country's first municipality-sponsored community center. It was added to the National Register of Historic Places in 1976.
