William Byas Gibson bought the property in 1857 and enlarged it, with the main brick section complete by 1872.","why_significant":"The house is a physical reminder of the Gibson family's influence on agricultural, commercial and civic affairs in early Woodland and Yolo County. Architecturally it is described as the only remaining example of Modified Classical style in a city rich in Victorian buildings. Its park-like grounds and fireproof brick construction also suit its use as a county museum.","narrative":"Set back from Gibson Road behind old trees and shrubs, this brick house in southern Woodland grew in stages from a small 16-by-20-foot wooden building. William Byas Gibson, a Virginia-born farmer and Shorthorn cattle breeder, bought the property and about 320 acres in 1857. He added a two-story brick main house, finished by 1872 at a cost of $7,000, and later a smaller brick wing. The main block reflects modified Georgian massing, with a hipped roof and a central hall plan. An 1879 lithograph shows two-story verandas. A classical portico of four Ionic columns was added later, probably between 1890 and 1910. The walls are plastered and scored to imitate stone. The house is valued as a reminder of the Gibson family's role in the agricultural and civic development of Yolo County, and as the city's only surviving example of its modified Classical style. Yolo County acquired the site for use as a museum.","period_of_significance":"1857","architect_builder":"unknown","architectural_style":"Modified Georgian / Modified Classical Revival, with Monterey-type veranda and Mannerist-Italianate influences","criteria":[],"status_note":"Owned by Yolo County and being developed as the Yolo County Museum.
