The James Couzens House at 610 Longfellow is a substantial three-story residence with a full basement and attic, measuring approximately 70 feet long by 50 feet wide. The home remained in the Couzens family for decades, passing from James Couzens to his son Frank, and later to Frank’s widow, who lived there until 1962. After her remarriage and move to Grosse Pointe, the house was exchanged for a residence on LaSalle Boulevard and transferred to the Catholic Foreign Mission Society, which still occupied the property in 1975.

Constructed of brick and stone, the house features a gabled roof, rectangular windows divided by stone mullions, and prominent bay windows along the south (front) façade. Mature, well-developed gardens occupy the west side of the property. The interior is distinguished by elaborate carved wood paneling, used extensively on the ground floor in large, high-ceilinged rooms.

While the second-floor rooms are equally spacious and well lit, they are noticeably plainer in detail. The third floor contains a full-length ballroom, three servants’ bedrooms, a trunk room, and a cedar closet. The basement is notable for housing one of the earliest semi-automatic bowling alleys in the country, an unusual and luxurious feature for a private residence of its era.
