The A.G. Thomson house is a good example of the Colonial Revival style. The style was prevalent in the United States for a long period of time ranging from the 1800s until the middle 1900s. Colonial Revival houses are typically symmetrical on the front façade and common to the style are small front porches to accentuate the entry. The front door is often highlighted with fanlight and/or sidelight windows.

The Colonial Revival encompasses numerous sub-styles including the Gambrel Roof style (or Dutch Colonial as they are often called) which is illustrated by the A.G. Thomson house. The Gambrel Roof sub-style was prevalent from approximately 1895 to 1915 and would occasionally include a rear cross gambrel as does the A.G. Thomson house. The Gambrel Roof sub-style accounts for approximately 10 percent of Colonial Revival houses in the United States. The roof dormers and multi-pane windows present on the Thomson house are also very typical of the style as is the one story, enclosed side porch to the left of the house.

Interesting features of the A.G. Thomson house first and foremost include its size. Gambrel Roof Colonial Revival houses were typically two stories with the gambrel roof enclosing the second story. The A.G. Thomson house, however, pushes the gambrel roof up to the third story creating a much larger curb presentation borrowing, perhaps, from the Neo-Classical style which was also fashionable during the era, but without the full height portico on the front.

Another noteworthy feature of the A.G. Thomson house is its strong influence from the Shingle style. The Shingle style was losing favor toward the end of the 1800s but this house still shows strong stylistic influences almost ten years later. The influences include the use of shingles as an exterior cladding choice although clapboard siding (and later brick) was far more common on Colonial Revival houses. The shingle style lacks trim detail on its vertical surfaces with no corner boards and very little or no window trim. Paladian windows were a frequent feature in the Shingle style and serve the A.G. Thomson house well as they were also occasionally seen in Colonial Revival examples.

The most redeeming feature of the A.G. Thomson house is that it still retains its original shingle siding, which would be a costly endeavor to replace today. Further, the house in general has been fairly well maintained and has not suffered from inappropriate remodels or additions. The 1919 addition to the rear of the house was done tastefully and is in keeping with the original house in both style and use of materials. The owner also kept true to the house’s design in the two out buildings on the property (a garage and a shop). The out buildings themselves show popular influences from the evolving Colonial Revival style both in the wide shed dormer of the garage and in the gambrel-end presentation of the shop (as opposed to the side presentation of the house). The interior, exterior, and the out buildings retain their original design integrity, shy of a few instances, and stand as a good solid example of a popular style of architecture on the American landscape.
