Diffusion Residence M is a minimalist home located in Montréal, Canada, designed by Alexandre Bernier Architecte. The architects’ vision for the M residence focused on defining spaces through physical and perceptual boundaries. This approach is evident in how the residence manages transitions—from public to private, from activity to rest, and from the individual to the collective. Their design prioritizes fluid movement and clear delineation of spaces that cater to both the vibrancy of family life and the need for personal retreat. The entryway defies the typical constraints of a functional passage, offering ample space for the family’s children to ready themselves for the day’s activities.

Mimicking the texture of the sidewalk, the mineral-tiled floor extends from the threshold, symbolizing the blend of the outside with the interior. The staircase within this area acts as a transitional element, demarcating the shift from the public sphere to the private home while a skylight above showers the space with natural light. Adjacent to the entrance is the office, a semi-public area designed to welcome clients or employees without disturbing the sanctity of the home. The continuity of the flooring from the entryway into this workspace reflects a modern necessity, accommodating professional engagements within the residential envelope. Drawing inspiration from Finnish architect Alvar Aalto, the design philosophy embraces the concept that a house should offer a seamless transition from outdoor to indoor spaces.

Aalto’s vision for a dual-faced residence—one presenting an aesthetic connection with the outdoors, the other offering warmth within—resonates through the M residence’s design. The rear facade’s transformation is a testament to this ethos. A full-length sliding door opens the house to the backyard, erasing the strict barrier between inside and outside. The integration of a garden shed marks the property’s boundary, while the garden itself becomes an extension of the living space. This outdoor area is designed for social gatherings or solitary contemplation, depending on the whims of the weather, turning the once utilitarian space into a celebration of nature within the urban fabric.
