Bioregional Building Materials Development | Summer Semester 2025

What range of natural raw materials can be found within a bioregion, and how can these be used as building materials?    

In the summer semester of 2025, students at HFT Stuttgart researched and analyzed which local raw materials from geological and biological reserves as well as industrial and agricultural production can be found in the Upper Palatinate region.

The focus was on the question of which waste materials are accumulated within local value chains and what potential lies in their recycling.

We then explored the region in cooperation with local stakeholders: samples were collected during short field trips and brought together in an exhibition. The potential of selected raw and waste materials as building materials was tested in practical experiments. Tests with different compositions open up visions of how the use of bioregional materials can contribute to the construction transition.

Cooperation project between the “Denk- und Macherei” and the Stuttgart Technical University of Applied Sciences, Faculty of Architecture and Design. Elective course in the interior design program, led by Dipl.-Des. Melissa Acker.
