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 heater, winter use. However, as the pine cladding wrapped the entire building, and the whole structure, despite insulation, thinner than in standard housing, typical solutions could not be used.
VELUX staff provided help on solving of the insulation issues, suggesting the use of foil normally applied in flat roof constructions, glued to the windows from all sides. This proved to be the most successful solution, although it caused a slow and precise work flow, as the windows are located very close to one another. Thanks to use of prefabricated wooden elements the construction of one hut, including the built-in furniture, took only two weeks.
