The Collin Family Home in Saint-Hilaire is recognized for its unusual interior architecture and its usage in the Prohibition era.

Built circa 1865 by Honoré Collin, this building is a vernacular adaptation of the Regency style. Originally, the front façade of the home overlooked the St. John River, as that was the only route of transportation present at the time of its construction. While it may look ordinary on the outside, the structure of this building is rather unusual in a few significant ways. In the basement, there are large, whole cedars with the bark still on, which support the rest of the house. The first-story floor consists of five-centimeter spruce planks. Additionally, the kitchen ceiling is built from rough timber beams, while the living room features a coffered ceiling with squared-off plank flooring. Knee braces consisting of spruce roots support the roof and second-story floor, joined to the floor by pegs that can be tightened as needed. These features blend together to create a seamless and attractive design.

The house is also notable for its role in the Saint-Hilaire bootlegging scene. Throughout the Prohibition era of the 1920s and 1930s, the house was the location of a bootlegging operation, which was aided by its unique design. The basement of the home is unusually tall, being more than three meters high, so liquor trucks could easily come in to be unloaded away from prying eyes. Alcohol was then stored in the roof space of the front veranda, accessible through the wall of one of the upstairs bedrooms.
