Henry B. Clarke House
Clarke House may have been modeled on the home of William B. Ogden. The Clarke house is often described as the oldest surviving house in Chicago, although part of the Noble-Seymour-Crippen House in the Norwood Park neighborhood was built in 1833. (However, Norwood Park was not annexed to Chicago until 1893.) The Clarke House was designated a Chicago Landmark on October 14, 1970. It was added to the National Register of Historic Places on May 6, 1971.
Chicago Mill Company Office Building
The Chicago Mill Company Office Building is a historic commercial building at 129 North Washington Street in West Helena, Arkansas. It is a single-story wood frame structure, whose Craftsman styling includes broad eaves and a wraparound porch supported by square columns. Built c. 1920, it housed the local offices of the Chicago Mill Company, one of the largest lumber concerns to operate in West Helena when that business was booming in the 1920s and 1930s. It is one of the few commercial buildings in West Helena to survive from that time.
