In a quiet residential street of Montréal-Nord, an existing six-plex has been transformed and extended to house two group homes for children aged 6 to 12. The project gathers these two units under one roof, completing the urban fabric with a calm, domestic volume that blends into the neighbourhood while offering a structured and protective environment.

The intervention doubles the surface of the original building to organize two distinct households of seven children each, every one with its own living room, dining room and activity room. Shared spaces – including a bright kitchen, offices for clinical teams, meeting rooms and a small Snoezelen room – support everyday therapeutic work and daily rituals, balancing moments of collective life with quieter intervals.

Architecturally, the project builds on the existing structure while reconfiguring it in depth. The volume is clarified, openings are reorganized and a compact contemporary extension completes the figure of the house, connecting the interior to a simple planted backyard through covered terraces and a white perforated-steel exterior stair.

Behind its quiet presence in the street, the building absorbs a complete change of use, from rental housing to a specialized care facility. New seismic elements, fire separations and efficient mechanical and electrical systems are inserted into the existing shell with minimal expression, allowing a soft, domestic architectural language to remain in the foreground and to support the everyday lives of children in Montréal‑Nord.
