It is also architecturally distinctive as a Downing cottage, apparently designed by architect Henry Cleaveland, and is possibly the only one in Chico.","narrative":"Known locally as the \"Little Chapman Mansion,\" this two-story clapboard house at 256 East 12th Street in Chico grew in stages over about thirty years. A brick pier foundation was laid in 1853, a small house was built on it in 1859, rooms were added in 1870 to form a T-shaped plan, and a second floor was added in 1874. The design follows A. J. Downing's \"Cottage in the Rhine Style,\" and architect Henry Cleaveland, who was in Chico at the time, possibly designed the additions. Augustus Chapman, a hotel, store and lumber mill owner, bought the property in 1870 and laid out the subdivision that became known as Chapmantown. Later owners included A. B. Collins and the Gilman Nelson family, who held it from 1883 to 1921. The house sits at an angle to the streets because it predates them, and the nomination describes it as possibly the only Downing cottage in Chico.","period_of_significance":"1800-1899","architect_builder":"Possibly Henry W.
