Designed to offer a living experience deeply rooted in the landscape, La Maison de la Baie de l’Ours establishes an intimate dialogue between nature and its occupants. Designed by ACDF Architecture, every architectural component resonates with the site — whether through blurred interior-exterior transitions, immersive pathways that dramatize movement from one zone to another, powerful horizontal framings created by deep cantilevers, or the use of stone monoliths that serve both as structural anchors and physical extensions of the terrain. The result is a unique form of immersion into the exceptional setting of Saint-Donat-de-Montcalm, in the heart of the Lanaudière region, north of Montreal.
Located on the shore of Lac Archambault, the house offers a living experience that is both enveloping and open. Despite its size, it remains discreet when viewed from the lake. It forms a protective, almost secret place — one that gives a sense of being sheltered, while still allowing for full immersion in the surrounding nature. Through careful framing, recesses, and controlled transparency, the project explores a subtle paradox: to see without being seen.
The architecture of La Maison de la Baie de l’Ours is articulated through three main elements, designed as complementary layers. Together, they allow the home to engage with the landscape in a refined and sensitive way.
The first element is a vast timber roof structure that defines both the architecture and the spatial experience of the home. Composed of glulam beams assembled into a coffered system, it creates deep cantilevers that extend the interior into the landscape. Appearing to float above the ground, this roof frames carefully composed views of the lake and surrounding mountains, while softening the boundary between inside and out.
The second element consists of a series of stone walls that function as both structural supports and sculptural gestures. Integrated into the terrain like natural extensions of the bedrock, they ground the house firmly within the site.
The third element consists of darker wooden volumes that house the bedrooms and service areas. Less open and more inward-looking than the main living spaces, these volumes are set back from the roof structure to create moments of privacy and retreat. Together, these three layers define an architecture that is both protective and open, with each part contributing to a nuanced and site-sensitive interpretation of place.
“We didn’t want to impose a shape on the landscape—we wanted to reveal what was already there,” says architect Maxime Frappier.
The living areas are organized in a fluid sequence designed to support both conviviality and privacy. The kitchen — with its cozy dinette — and the sunken living room open wide to the lake. At the center of the plan, the dining room enjoys a double visual connection to both the forest and the water, deepening the immersive experience.
The fireplace serves as the central gathering element. Visible from all shared spaces, it anchors the kitchen, dining room, and living room, creating a warm, unifying presence around which domestic life revolves.
A secondary kitchen, hidden within a dark wood volume and accessed via a discreet passage, supports gatherings without interfering with the main social spaces. To the rear of the kitchen, a large screened terrace unfolds beneath the roof’s overhang. Equipped with retractable mosquito screens, it becomes a true outdoor living room—protected from the elements and insects, while remaining in constant dialogue with nature. An outdoor fireplace placed in perfect alignment with the indoor hearth creates a striking symmetry. From the kitchen island, both fireplaces are in view, reinforcing the continuity between interior and exterior, and heightening the immersive connection with the landscape.
Flanking the central living spaces are two distinct wings — one dedicated to the parents, the other to the children. A partial upper level, located above the children’s wing, houses a guest suite and the family’s workspaces, providing both privacy and spatial fluidity in daily life.
The primary suite is accessed via a glazed corridor, designed as a true threshold between shared areas and a quieter world. Bathed in light and open to the surroundings, this passage enhances the sense of retreat and eases the transition to a slower, more peaceful rhythm.
The parental suite includes a lake-facing bedroom, an intimate lounge, a generous walk-in closet, and a bathroom that opens onto the forest. The seamless spatial flow between these elements creates a sensory continuity with the surrounding landscape, encouraging calm, introspection, and a deep connection to nature.
Outside, a sunken terrace, bordered by built-in benches and a fireplace, extends the atmosphere of calm and reflection. Nestled into the terrain, it invites deep connection with the elements — water, wood, and stone — offering a living experience that is both immersive and grounded.
The children’s bedrooms open generously onto the landscape and have direct access to a private terrace — an ideal spot for relaxation in nature. From this terrace, a small wooden bridge crosses over a planted zone to reconnect with the main terrace. This simple gesture reinforces the connections between the project’s different layers, and enhances the continuity between indoor and outdoor spaces.
La Maison de la Baie de l’Ours expresses a vision of architecture in which form, material, and lived experience come together to reveal the richness of place. Far from imposing a spectacular gesture, the project focuses on unveiling what the site already offered: light, topography, proximity to water, and the density of the forest.
Through precise composition, honest materiality, and constant attention to spatial experience, architecture here becomes a medium of connection — between people, between interior and exterior, between the built and the natural.
