[2] The Brisbois House is two-and-a-half stories tall and built from locally extracted gray limestone.

Fluted Doric columns flank the front entrance, and molded trim forms the rest of the doorway; the lightness of these features reflects a Federal influence.

According to the investigation, Michael's son Bernard Walter Brisbois most likely built the house for himself and his widowed mother circa 1840.

While a building of the house's style and permanence would have been uncommon in the early 1800s, it fits the 1840s pattern of more elaborate homes being built for wealthy Prairie du Chien residents.

It is one of the most well-crafted extant homes in the city which dates from before 1850, and it is one of the oldest standing stone houses in Wisconsin.
