The new living room ceiling above the new carport was constructed as a HBV panel ceiling. This way the whole building could be stiffened. Additionally there was an energetical remediation by insulation between the rafters and a thermal insulation composite system of the walls, entirely following the KfW energy-efficiency standards. The new cubic building is now used in all three floors: On the ground floor the new HBV panel ceiling forms a carport for two cars.
On the top floor the living space was expanded from 58m² to 100 m², and the roof is used as a deck. This innovative idea was topped off by a front facing made of horizontally mounted larch timber, giving the cubic shape a modern look.
