Wood is not associated with the destruction of nature, but it has to be degraded with the attributes "cheap", "not very durable" and "poor". It was once the material of times of need. As a building material, however, the purely natural product is not to be despised. Since wood breathes, it is an ideal climate regulator, even thin wooden walls insulate well. Their thermal insulation is also sufficient. And it appears - compared to steel, glass and concrete - to many people cozier and sweeter. Beyond the romanticism of a log cabin, an atrium house was built in Kuchl near Salzburg. The architect couple Christine and Horst mainly used larch and spruce wood and, for special areas, also industrial multilayer panels. The frame construction was made of larch wood. The horizontal formwork is also made of larch wood and will take on a weathered, gray appearance over the years. The house closes the cold north side and has not a single window in this direction. The insulation consists of waste paper (cellulose). Paper granulate was provided with a binding agent and blown into cavities. The construction costs of the house with 240 square meters of living space, in which a family of five lives, were kept within limits at less than 20,000 Schillig per m².
