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.
Flatiron Building (Atlanta)
The English-American Building, commonly referenced as the Flatiron Building, is a building completed in 1897 located at 84 Peachtree Street NW in downtown Atlanta, Georgia, on the wedge-shaped block between Peachtree Street NE, Poplar Street NW, and Broad Street NW, also creating a one-block break in Williams Street. It was completed five years before New York's Flatiron Building, and shares a similar prominent flatiron shape as its counterpart. It was designed by Bradford Gilbert, a Chicago school contemporary of Daniel Burnham, the designer of the New York building. The building has 11 stories, and is the city's second and oldest standing skyscraper. The Flatiron building is protected by the city as a historic building in the Fairlie-Poplar district of downtown, and is listed in the National Register of Historic Places.
