The concept imagined by the association developed around the theme of duality, recreating the existing volume through a “sister house”, or Maison Soeur, that sets out through its clean signature. The residence is a veterans’ home, common dwelling of Montreal’s 1950s working-class neighbourhoods, it was imperative to honor its architectural heritage. The stakes consisted in emphasizing the volume characteristic to this type of building, while providing it a second life that better answered to the new owners’ need for space. The extension thus displays itself as a reinterpretation of the prevailing structure, through its silhouette and its physicality. The roof’s double-sloped archetype is duplicated, as is its masonry envelope.

In the later extension, openings and luminosity are accentuated by large windows. The layouts of the interior spaces are distinct, favoring connexions between the indoor and outdoor spaces. The layout ensures copious light throughout the interior spaces, whose pale hues contrast with the dark brick of the newly designed facades.
