Mass tourism, the advanced automation of the salt industry, migration and aging, and, last but not least, the protection of nature and cultural landscapes are the themes of the Salzkammergut in Upper Austria. In Hallstatt, a mountain village at the foot of the Dachstein-mountain, these developments are coming to a head. The population of 800 inhabitants is confronted with 200,000 tourists each year, usually arriving with coaches in large tourist groups for a few hours. This overwhelmes the infrastructure of the place, with all consequences for the natural environment. One viewing platform after another is built on still more exposed locations. Ropeways, parking lots and souvenier shops have a boom. In addition to uprising tourism, the traditional salt mining industry as an employer is getting smaller and smaller. Few highly-qualified staff is needed, which is driving the exodus of the young, well-educated. The topic of my work, the House of Nature, shall selfconsciously oppose these tendencies. A house with a contemporary, high-quality architectural design will draw attention to these problems, which are also problems of natural protection. With the local building materials of wood and stone, this should provide a forum for information, discussion and research, and thus also sustainable jobs. It should also be an example for the local population and show that the traditional building heritage can be pursued and made ready for the future even without plastic windows and cheap thermal insulation façades.
