The original house was constructed around 1807.
This is a Georgian style, clapboard house on a raised basement.
The first floor had two rooms with a rear hallway.
Each of the rooms had a separate entrance door to the front porch.
Because these doors were very close to each other, a false door was built between them.
They were framed together to result in an architecturally pleasing facade.
Both of these rooms have fireplaces with carved Federal mantels.
The door frames and moldings are also in Federal style.

The south facade has a portico supported by four Doric columns.
The pediment has a semi-elliptical window.
It is decorated with dentate molding.

The south facade has single nine over nine lights on either side of the doors.
Each wing has four nine over nine lights evenly spaced.
In the second story, there are pairs of six over six lights to the left and right of the porch gable.

The single-story wings were built in the 1930s.
The east wing has two rooms with a fireplace.
The west wing has three rooms.
Two of these have fireplaces.
The wings use a Greek Revival style for the mantels and woodwork.
The rear hallway extends along the north side of each wing.

A floor plan of the first floor with the wings has been published.
