The project Hadlaub contributes to the discourse on nature-based design and the relationship between wood and wellbeeing. Influenced by the Japanese bathing culture, an architecture was created that appeals to all the senses of the body. The precision of the craftsmanship creates a sensual atmosphere in which everyday rituals can be celebrated. We experience the feel and scent of the materials in their raw state. The grain of the wood, the texture of the stone, the scent of the Hinoki bathtub, the natural shadows cast, the dim lighting of the toilet - All these details evoke a special mood and aesthetic that are in harmony with our idea about life and the flow of time. The basic idea of giving autonomy to the spaces and at the same time bringing them into a balanced relationship with interior, intermediate, exterior and metaphorical space is expressed in the integral design of the window coverings for the living room and bedroom. Here, the carpenter developed sliding windows in the form of a wooden lattice that can enclose the space or make it permeable, depending on their position. In this way, the respective change in the room also affects the perception and experience of the same. The incident light also draws a geometrically composed shadow image into the room. The bedroom wing with the bathroom was radically redesigned. The core task was to enable a Japanese bathing culture, namely a division into wet and dry areas and an intimate toilet. If you enter this living area through the original shoji sliding door with the Japanese calligraphy "Bamboo" by Shotei Ibata, you are led past the dressing room to the bathroom by a continuous slatted frame made of fine maple rods, a masterpiece by the carpenter. The built-in cupboard and toilet door open inconspicuously in the wooden panelling. In the wet area, which is separated by glazed sliding panels, the centrepiece is located on the black-polished coarse-grained concrete plinth: the original Japanese wooden bathtub, whose essential oil of Japanese cypress fills the room with a wonderful fragrance. The massive chrome steel fittings, reduced in form, also fit slenderly into the wooden structure. Opposite, the entrance leads to the tatami bedroom, which, like the toilet, is artfully finished with a natural clay plaster applied by Japanese clay builder Tatsuya Tokura. Tokura modelled the pattern of a slowly flattening wave on the wall in the bedroom, intentionally giving the room a washed-out texture. The ceiling was made with planks and struts of larch wood. The sideboard furniture at the futon top end was made from an old untreated trunk of red cedar. The captivating and unifying element of this entire sequence of rooms is the continuous wooden floor made of dark ash parquet cut out in the Japanese Naguri technique. It holds the room elements of this intimate complex together.
