It also stands on the site of the Fernandez waterfront enterprise, begun in 1854, which became Pinole's first operating industry and a trading port.","narrative":"Built in 1894 for Bernardo Fernandez, this 20-room mansion at 100 Tennent Avenue in Pinole is a two-story wood-frame house over brick, with attic rooms and a full basement. Its eclectic design combines Second Empire, Queen Anne and Eastlake elements, a mix often called the San Francisco Style. A monumental exterior stairway leads to a spindle-work porch, and a tower-like projection rises to a small mansard roof with dormer windows. Inside, features include a pressed leather wainscot, oak floors with inlaid borders, walnut balusters and a living room divided by an archway with Doric columns. The house sits on the site where Fernandez began a waterfront business in 1854, which became the first operating industry in Pinole. His docks, warehouses, shipping and mail service made the landing a trading center for West Contra Costa County. The nomination describes the mansion as the only significant house of its era and style remaining in the city.","period_of_significance":"19th Century; 1894 (construction)","architect_builder":null,"architectural_style":"Eclectic late 19th century \"San Francisco Style\" combining Second Empire (French Mansard), Queen Anne and Eastlake, executed in wood","criteria":[],"status_note":"Listed as in good condition, with a continuing restoration program in progress; the form describes it as a private residence and notes a conversion of the original library to an office.
