It has a pyramidal roof with a small front gable to one side, clapboard walls and an asphalt roof. A double gallery runs across the front and south side, with flat balusters on both floors. The original porch supports were replaced with two-story square brick columns, while round half-columns on brick piers also appear on the ground-floor porch. The main entrance has a triple bay, with windows on each side of a door framed by sidelights and a transom holding good leaded glass. Windows have one-over-one lights, and an interior brick chimney rises through the house. The property sits on a well-kept, prominent corner lot in a residential part of the Heights. It is noted for its architecture and because it remains in the hands of the builder's family, still serving as a residence.","period_of_significance":"1900--","architect_builder":"Paul W.
