The walls and roof have a simple wooden structure and pine cladding. They are well insulated and rear-ventilated, which allows a good climate in the summer and, with electrical heaters, a good indoor temperature in winter as well.
As the pine cladding wrapped the entire building, and the whole structure is thinner than in standard housing, typical solutions could not be used.
Thanks to use of prefabricated wooden elements the construction of one hut, including the built-in furniture, took only two weeks. First cabin was opened to the public in May 2017, the rest followed during the course of summer.
