The Grotto Sauna perched at the north-west edge of a private island in Toronto, Canada is not only a cool place to relax, but also has a beautiful smooth design. The 800-square-foot freestanding sauna carefully sits on the island's prehistoric rock formations.
The builders are the PARTISANS. They’ve selected a concept of solid, simple presence on the exterior, while the interior followed dynamic air movements in curvature forms.
To minimize disturbance of the age-old rock, PARTISANS used a Leica 3D scanner to create a site model before working on the freestanding sauna design.
