The coastal sauna named Löyly is located in Hernesaari, a former industrial area of Helsinki (FIN), which is currently being renovated. The sauna is an integral part of the Finnish way of life. Located directly on the waterfront, Avanto Architects have added a sharp-edged structure to the coastal landscape. Löyly sits on the harbor pier like a "stealth building." The building can be experienced 3 dimensionally via the terrace, the roof but also from the water. The uses include the next to the sauna, a restaurant and viewing terraces.
