Designed by Finnish firm K2S Architects, Ltd., the Sauna Sirola is built on a narrow site between the rocky sides of a lake and a gravel road. The V-shaped scheme sets two facades, one, sheltered and bright, oriented towards the water, and the other on the back, separated from the road by a protection wall. The building comprises a living room, a sauna and an open-air recreational space [materialicious / arkinetia blog].
