SUSTAINABLE MATERIALS – LISI consists largely of renewable resources and sustainable materials. Wood is used as a raw material for construction and insulation. Not only is it carbon-neutral but it also has a positive effect on the indoor climate and comfort in the home. As a natural product, wood is the ideal material for a prefabrication of houses – ease of use and transport. Under the aspect of the conscious handling of raw materials, the LISI house is designed to use all parts of the tree – from heartwood to the bark. Wood is therefore not only used as a construction material, but also inside the walls and ceiling panels, or in the furniture. Thus, the wooden structure is can also be felt and smelled.
