Only this type of building is selfliquidating by saving energy. For example-a 2-storey house with surface 200 sq. m. selfliquidates for 8 years. The heat isloation of the walls is the same as 90 cm brick wall. The final surface and everything at all in these houses is at client's choise. The construction happen on client's plot within 45 days for key. Before that for 30 more days the elements are prepered for assembling.
