The old, concrete trade union building from the 1970s, designed by the Japanese architect Yoji Kasajima, helped to shape a clear concept. Tradition, balance, nature, contrast, enjoyment and tranquility have been the watchwords of the concept. True to Japanese tradition, the natural environment; light and transparency in the building materials have played an important role in the project. The result was a modern, asymmetric version of a Japanese emperor’s courtyard, with a large swimming-pool as its architectural heart. Several small huts, were created around the pool for different purposes, where the experience of cold and warm are constantly in focus, in everything from salt steam sauna to carbonated bath, rain showers and alpine tub. Some huts are in concrete, others with part trellis-clad components. The experience is in focus.
