Clark by builder Fred B. Butterfield.","why_significant":"The house is presented as an outstanding example of Victorian design combining Eastlake ornamentation with bays and gables, with a high degree of architectural and historic integrity. It is also tied to William S. Clark, a banker, real estate developer, businessman and mayor who helped shape the growth of southwestern Eureka through Clark's Addition.","narrative":"Built in 1888 at the corner of 14th and C Streets in Eureka, this redwood cottage is covered with Eastlake ornamentation. Fred B. Butterfield supervised the skilled craftsmen who built it for William S. Clark. The one-and-a-half-story house has a hipped roof, side and front gables with hanging stickwork grillwork, square and slanted bays, and an elaborate entrance porch with spools, sunbursts, scallops and pierced cylinders. Inside, the parlors and dining room keep their darkened natural woodwork, oak graining, plaster medallions and polished mantels. Clark was a banker, real estate developer, businessman and twice mayor of Eureka. He and his father subdivided and enlarged Clark's Addition, a large residential area of southwestern Eureka. The Clarks lived in the house until 1923, and it was later divided into apartments without major damage to its character. A 1906 remodeling and some later changes were modest, and the house keeps a high level of integrity.","period_of_significance":"1888 - 1923","architect_builder":"Fred B.
