A living dialogue with erosion and tradition in sustainable design

Above the dunes of Havre-Aubert Island, Magdalen House by atelier l’abri offers a masterclass in sustainable seaside architecture. Every design choice reflects a commitment to preserving the island’s dynamic coastline with eco-friendly practices. Situated on a plateau above protected sands, this compact home integrates seamlessly with its environment, honoring the historical building techniques of the Magdalen Islands.

Sustainable design: Strategic siting for ecological harmony

The house is thoughtfully placed away from the shoreline, safeguarding the dune ecosystem that thrives on delicate balances among vegetation, sand, and sea. The structure features timber piles that stabilize it along the most secure edge of the plateau, minimizing excavation and concrete use while maintaining breathtaking views of the surrounding landscape. This strategic siting is an integral part of the home’s environmental consciousness.

Respectful coexistence with local wildlife

The dwelling coexists peacefully with its natural neighbors, including birds and foxes, positioning itself as a non-intrusive architectural element. Its restrained design approach fosters a harmonious relationship with the native ecosystems, embodying principles of ecological design.

Reflecting a resilient architectural heritage

The design embraces a simple gable form and cedar shingle roof — hallmarks of the local Acadian style developed between the late nineteenth and early twentieth centuries. atelier l’abri sees this typology as evolving knowledge, akin to Nathalie Thibodeau Architecte’s approach with La Maraude.

Natural materials withstand maritime wear in sustainable design

Cedar shingles encase the exterior, aging gracefully to a silver-grey patina. Eastern hemlock supports the terrace, chosen for its durability against the elements, while marine-grade stainless steel mesh guardrails resist corrosion from salt air. These materials choices are all rooted in an environmentally sustainable ethos.

Interior connections to landscape and craft

Inside, pine flooring and paneling complement North American natural stone, maintaining a connection with the view outside. Local craftsmanship shines through in the fixtures and finishes, from Quebec-made lighting to custom millwork by Cap-aux-Meules artisans. The art and ceramics are island-made, adding intimate, handcrafted touches.

Efficient spatial design enhances living experience

The heart of the home, a central service core, includes the kitchen, utilities, and a staircase leading to a mezzanine. This layout prioritizes function while ensuring key living and sleeping areas access stunning natural light and wide vistas. A double-height living space extends the site’s immersive beauty indoors, further demonstrating the principles of eco-conscious design.
