Decorative wood brackets extend down along facade to second floor banding.

Historical Summary:

In contrast with the ornamented Queen Anne or Stick style houses of the mid to late 19th century, the design of this residence exemplifies the new simplicity, formality, and symmetry distinguishing Oak Park houses around 1900. The rusticated stone foundation and large fluted columns recall historical styles, but the rectangular masses and geometrc detailing reflect on interest in Prairie style principles. The clapboard exterior is divided by a prominent stringcourse, and windowed dormers project from the steep hipped roof on all sides (Ridgeland Revealed, p28).
