The two-story, frame, front gabled, Colonial Revival house is symmetrical in plan, with the exception of the wrap-around porch.

It features Georgian corner pilasters, pedimented dormers, wooden belt courses, an Adamesque-style cornice with dentils and decorative modillions, and an elliptical fanlight.
