A young growing family was excited about the idea of enlarging the ground floor of their 5-plex situated in Rosemont-Petite-Patrie. As they wished to keep their upstairs tenants, the clients agreed to sacrifice a portion of their backyard for the extension.

The 1350 sqft extension that we’ve nicknamed “the couleuvre” (the garden snake), includes a new staircase on the ground floor plan, a master bedroom and a bathroom. The ‘kids zone’, comprised of 3 bedrooms and an open concept bathroom, dominates the second floor.

The architectural parti consists of an angular black volume with spots of white, which twists and turns in a snake like manner, wrapping itself around the master bedroom clad in bricks salvaged from the demolition of the old garage.
