Lehm Ton Erde office building

The three-storey office building, constructed from load-bearing rammed earth and connected directly to the production hall, has grown over the past six years with plenty of dedication and perseverance, as well as a great deal of hands-on effort. Today, it brings together the diverse activities of Lehm Ton Erde Baukunst GmbH under one roof.

In one room, construction sites are planned and coordinated, while prefabricated components are produced next door and new production techniques are tested and refined. In between, students diligently polish their Dorodango spheres. Planning, production, workshops and research are integrated here, creating real synergies and encouraging the transfer of knowledge. Throughout the building, earth can be experienced in (almost) all its forms: as solid rammed earth walls and wall linings; as clay plaster; as a rammed earth floor and loose infill; in the casein finish on timber surfaces; and as a timber–earth composite slab, which is a further development of the ceiling system first realised in the Hortus project. Local, vapour-permeable materials were consistently prioritised out of conviction and respect for the location.

 

The office serves as both an experimental field and a showcase for our own craftsmanship and that of local partners. Visible throughout are rammed earth walls and floors, ornamental tiles, custom-made lights by Karak, a casein floor developed in collaboration with David Ledetzky and on-site, hand-woven shading elements by Emmanuel Heringer. In short, this is a building that demonstrates what can happen when many hands, curious minds and a shared ambition come together. Or, to put it differently: it’s amazing what you can build with a little help from friends.

Production type
In situ production

Covers the entire on-site process — from setting up the project-specific formwork & compacting the material to final finishing and detailing.

Prefabricated production

Factory-based production, including the creation of production plans, mixing & tamping, as well as drying, packaging, & transport.

Services
Production techniques & machinery

Planning & provision of the essential infrastructure, machinery rental & production techniques. Services of design & protoyping of customized, project-specific solutions.

Research & development

In cooperation with universities & other research institutions, as well as for feasibility studies to excel solid & massed construction techniques with earth-based building materials.

Advice & planning

We offer comprehensive technical expertise for rammed earth projects, from initial consultation to detailed specialist planning across all project phases.

Knowledge transfer

Workshops & training programmes for a wide range of building-sector professionals, focusing on solid & massed earthen construction types, complemented by expert supervision.

Recipe development

Customized research & development of rammed earth mixture – from analyzing local sources or excavated material to adjusting the recipe to fulfil pre-defined expectations.
