Milpitas Ranchhouse

Why it's listed
Built between 1929 and 1930 in the San Antonio Valley south of King City, this ranch house served as headquarters for William Randolph Hearst's ranching operations. Architect Julia Morgan, who was designing Hearst Castle at San Simeon at the same time, laid it out in a modified double E plan with a central arcade, towers, and a cupola. Reinforced concrete, whitewashed to resemble stuccoed adobe, forms the walls, and the roof is handmade red clay tile. The design echoes nearby Mission San Antonio de Padua, about half a mile away. Hearst reportedly used the building only occasionally, mainly the dining room. The Army bought about 164,000 acres from Hearst in 1940, and the house became part of Fort Hunter Liggett. It has since served as housing for soldiers, an Officer's Club, and a guest house. Modifications since 1940 have been minor, including interior murals and updated bathrooms and kitchens. At the time of listing it was 47 years old.
Significance in brief: The building is significant as the work of Julia Morgan, the first woman licensed as an architect in California, and for its association with William Randolph Hearst and his ranching operations in the San Antonio Valley. It is also a well-designed example of Mission-style architecture, sited near Mission San Antonio de Padua. It remains largely unaltered since the 1930s.
