Building with clay and rammed earth is as old as the history of mankind, yet the material continues to be as modern and contemporary as almost any other building material with regards to its ecological properties and building physics. Martin Rauch was introduced to earthen building not by architecture, but rather through his training and early work as a ceramicist, stove-maker and sculptor. Within the last 35 years, he and his company, Lehm Ton Erde, have developed and implemented many techniques and projects relating to rammed earth. Crucial in the material’s development is not only continual improvements in production processes and possibilities, but also its establishment within contemporary architecture and aesthetics. Many buildings and installations have been realised in collaboration with international and renowned artists and architectural offices, which has enriched building with earth both from a technical and creative perspective.
