For the surfaces of the interior construction were almost exclusively raw larch 3-layer panels used. This consistency creates a uniform, calm impression, which exudes an exceptional cosiness due to the used material. The functionality of the multilayer panels is fully utilized for the construction of the installations. Natural lime plasters, lime paint and rough sawn spruce boards cover walls and ceilings in an equally ecological manner. The handling of existing beams, which assimilate the modern fixtures, shows the cautious approach to rehabilitation. The incurred spatial relationships provide insights and create new living space. The radiant warmth of the wall heating and the tempering system of the enveloping surface ensure a pleasant and healthy room climate.
