The site is situated in Ranco in the Lake District - Chile, over a dark granite rock at the shore surrounded by mountain cypresses.

The project consists of a sauna with a roofed terrace and a change room, each of them looking towards different views from the rock to the lake. The three of them connected by a north-south oriented circulation.

The interiors are clad in Alamo, a kind of cottonwood tree; on the other hand the exterior is clad in oak wood because of its strength in harsh weather conditions which will turn grey, similar to the original buildings in the area.
