Patrick Ranch is an excellent example of the type of home built by large landowners in Sacramento Valley during the last half of the 19th century. The house was built by pioneer rancher William Northgrave on land once owned by James Marshall.

The substantial and well crafted residence has the general character of an Italian villa. The bracketed wooden cornice and window dressings give it the Italian style; however, the balustraded walk on the roof and the lathe work on the porches are reminiscent of early New England sea coast homes. The architectural classification would probably be California eclectic.

The carpenters and stone masons were the same men who built the Bidwell Mansion in Chico. The architecture of the Patrick House is similar to that of the Bidwell Mansion with some modification.
