The Green Cabin, designed by Daymark Design Incorporated, is a 576-square-foot, boat-access-only retreat located on Roberts Island in Georgian Bay, Ontario, Canada. Completed in 2024, the cabin serves as a seasonal extension to an existing cottage on the property. The cabin is a contemporary interpretation of traditional cottage aesthetics, respectfully designed to complement the existing structures on the island. It features a standing-seam metal cladding that creates a continuous surface from the roof to the walls, giving it a sleek, modern appearance. Situated on a rugged, rocky outcrop, the cabin is oriented to maximize views of the expansive Georgian Bay. Its position was carefully planned to meet zoning bylaws and avoid obstructing views from neighboring properties. The all-metal cladding was chosen for its durability, protecting the structure from the severe weather conditions of the Georgian Bay region, including high winds, heavy snow, and lake exposure. A thin steel drip edge acts as a protective "eyebrow" over windows, directing rain away from the facade. In contrast to the restrained exterior, the cabin's interior is colorful and playful, with sloped ceilings and large windows that create a vibrant atmosphere. The space is designed to be versatile, functioning as a guest room, a lounge, or a workspace. The cabin is elevated to protect it from fluctuating lake levels and built to withstand the region's extreme climate. Small awning windows framed in natural ash allow for cross-ventilation during the warmer seasons, acting as "portals" to the surrounding nature. A centrally located skylight illuminates the interior, enhancing the sense of space and tranquility. Project credits Architect: Daymark Design Incorporated.
