In January 2025, Antonia Trager, a student assistant and Master's student at the University of Liechtenstein, delivered a guest lecture at Bauhaus-University Weimar. The invitation was extended as part of the university-wide lecture series Tomorrow’s Menu, organised by horizonte.

In her dual role, Antonia Trager spoke on behalf of the company Lehm Ton Erde as well as the earth HUB at the University of Liechtenstein. Her lecture focused on the philosophy and sustainable possibilities of earthen construction—particularly the material clay casein.

The event attracted great interest: both the lecture and the subsequent workshop were fully booked. Participants had the opportunity to experiment with the material themselves and engage in an in-depth exploration of the properties and applications of sustainable building materials.

The company Lehm Ton Erde was founded by Martin Rauch, who has been combining traditional craftsmanship with innovative technologies in earthen construction for over 30 years. His main focus is on rammed earth techniques, which enable resource-efficient building with a high standard of design quality. In recognition of his outstanding contributions to this field, Martin Rauch was awarded an honorary doctorate by the University of Liechtenstein in 2023.

Through this guest lecture and workshop, an important contribution was made to the discussion on sustainable building, fostering an exciting exchange between research, practice, and education.
