Inspired on the Te Mazcal, a native central/ north American traditional ritual that takes place inside a sauna, this timber structure was designed to be assemble and dismantle in about 3 hours. Notched timber portals meet at the central ring plywood connection. Two tensioned steel cables hold the tension on the structure avoiding it to flatten. Two layers of canvas hold a thick layer of recycled INSULPRO insulation while a log burner provides the heat for this nomadic sauna to host 15 people on an unique urban experience. Outside a bath filled with cold water is waiting for the users for a refreshment. A series of changing rooms built with pallet timber enhance the contrast between the public and private environments brought to contrast in the project.
