Inspiration came directly from the site, an island located in Georgian Bay, Canada. The unique and rugged landscape is a prehistoric geological record, carved by shifting plates and glacial erosion. We were also inspired by the notion of a Grotto, a secret internal world, internally carved by natural forces. Thus, we were inspired to create a piece of architecture that evolved out of its surroundings. Outside, the sauna is a mysterious object embedded in the landscape, while within awaits a sublime world of complexity, wonder and delight.
