Welcome to LehmTonErde

Lehm – Ton – Erde. Loam – Clay – Earth. These three words has been significant for the work of Martin Rauch for over 30 years. For us these words have a symbolic character and describe the whole philosophy of our work. Loam stands for handcraft and technology, Clay for artistic design, Earth for the sustainability of earth construction.

The company is based on our wide experience and ongoing innovation. We are capable of designing, planning and realising projects of any size. In our projects we set our standards very high. The focus of our work is concentrated on the rammed earth building technique – proven over thousands of years with new perspectives and developments.
