An Ontario Haven Designed In Deep Dialogue With Nature

A commitment to sustainability defines the work of Toronto-based Dubbeldam Architecture + Design, led by founder and principal Heather Dubbeldam. That commitment, which is present online and through media coverage, led to a commission for an off-grid residence in Muskoka, Canada for a professional couple. The clients, who had already purchased land for a lakeside retreat, were drawn to the firm’s values and design approach. Consulting with Dubbeldam, the clients requested “a front-row seat to the forest and the lake.”

Before the home was designed, the couple camped on the 180-acre site to understand the area and pinpoint exactly where to build. “This experience let them get to know the site in a very genuine way: Where the early light hits, which areas stay coolest on hot afternoons, and where the best breezes move through at night,” Dubbeldam says. She integrated this place-based knowledge into her design, maximizing the connection between indoor and outdoor spaces.

Dubbeldam Architecture Embraces Nature In This Off-Grid Escape

The two-level home maximizes views of the surrounding trees with expansive floor-to-ceiling windows. On the upper level, the living and dining areas feature dramatic lake views. Family members can dine at a custom oak table, gather around a cast concrete hearth, and perch upon a 17-foot window bench. Stone and white oak millwork define the airy kitchen. Bedrooms are on the lower level, each with dedicated exterior entrances for easy access to the outdoors. Natural light floods the home, and every circulation route ends in a large window.

Throughout the residence, the architect relied on natural materials and neutral furnishings. “Every finish was chosen for its quiet presence and tactile quality, allowing the interior to harmonize with the surrounding landscape rather than compete with it,” Dubbeldam explains. “And all of the wood species were sustainably harvested and milled in the region.” Grayed cedar and charcoal-stained spruce define the exterior, complementing nearby trees. Inside, hemlock ceilings and oak floors bring texture and warmth.

A Home That’s Sustainably Rooted

When the couple first camped on the site, they had to paddle across the lake to reach their land because there was no existing road. As construction of the residence began, a new road was constructed to bring in materials and workers. There were plenty of challenges during construction, including heavy snowfall and temperatures that dropped below safe working levels. And Dubbeldam carefully considered each tree that was removed, working to minimize impact. “This approach is what gives the cottage its feeling of being completely immersed in nature,” she says, “with the trees remaining close enough to create an intimate connection to the landscape.”
