Fritz-Pflaum-Hütte, Design StudyTUM × ETH Zurich
Design study for the German Alpine Club, Bayerland Section This design study explores the repair and extension of the Fritz-Pflaum-Hütte for the German Alpine Club. It was developed by the Professorship of Digital Fabrication at the Technical University of Munich together with the Chair of Architecture and Human Augmentation at ETH Zurich. The work builds on the master’s studio and a joint survey of the existing hut.
The existing annex is dismantled, with its stones to be reused in a new extension on the uphill side. This houses the entrance, dry toilet, water point and storage. The additional roof collects rainwater, leaving the main hut for cooking, shared living and sleeping. Curved rows of shingles run across the roof and façades, with their arrangement planned digitally.
As a student assistant at TUM, I was responsible for the 3D visualisations, point clouds and renderings, as well as the building services concept and its diagram. The drawings were developed within the project team. The study shown here records the design stage of August 2026.
