While searching for an ideal site in the Bavarian region of Germany for the bioregional construction of a hemp house, the occurrences of local natural resources such as hemp, wood, clay, limestone, and granite were identified and recorded. The resulting mapping of bioregional materials with their potential for the construction sector was analyzed in order to identify the areas offering the greatest potential for the regional supply of building materials. Four circles with a diameter of 50 km thus define these locations.

   Subsequently, by focusing on the materials available within one of these areas, the land area required to build 100 standard houses using only these materials (excluding technical equipment and accessories, for the purposes of this exercise) was represented. Our analysis therefore demonstrates the feasibility of bioregional and ecological construction, despite current limitations related to infrastructure. Nevertheless, this approach offers an innovative vision of how sustainable architecture can rethink and revitalize local resources.
