Located in a former industrial red brick neighbourhood, the 540 square metre Finnish pine sauna complex has been inserted in a former customs checkpoint, which later served as a warehouse building.
The design aims to build upon the notion of the late nineteenth century korttelisauna, or neighborhood sauna, where the community would come to fulfil basic hygiene needs.
Eager to respect the sauna's industrial past, while creating an authentic and "honest" sauna experience, the architects have layered the building's rough concrete finishes with natural, warm Finnish pine that is traditionally used in saunas in the country.
To create a cosy interior space, and to isolate the sauna from the city outside, the exterior windows are specially treated to create a soft and milky in appearance that evokes steam from a sauna.
"The resulting ambiance is a calm, peaceful one that creates a resounding appetite for sauna from the moment one steps inside," said the studio.
"Above all, the resounding commitment towards maintaining the integrity of the sauna experience echoes throughout Tullin Sauna, ultimately establishing a reliable, truthful, and welcoming living room that hosts the local community and beyond – a result we feel is perfect for the sauna capital of the world!"
