Cement-Free Residential Building: Building Culture of the Future in Earth and Timber

The building in Dornbirn was realised as a prototypical contribution to the development of resource-efficient construction methods using load-bearing rammed earth and timber. The aim was to implement a fully load-bearing solid structure made of prefabricated rammed earth elements under real conditions of use. Lehmit was involved in the project as specialist planner for the slab and the connection details.

House in Nofels: Densified Building in Earth and Timber

The single-family house in Nofels is defined by clear, functional architecture and the use of regional materials. The building responds to the conditions of its site: because of the existing development to the east, a compact form was chosen for an infill development. A low connecting structure links the new building to the existing one, serves as the main entrance and leads into the garden via a gently rising ramp. A terrace on the south side extends the living space and offers a shared place to gather outdoors.

Thermally Activated Earth-and-Timber Slab in the Lehm Ton Erde Office Building

In the new office building at the Lehm Ton Erde workshop hall, a timber beam slab with an earth infill and additionally integrated thermal component activation was realised. The space serves as an office and at the same time as a hands-on development field for the interplay of timber structure, earth mass and thermal activation.

Research Project Timber Earth Slab (TES) with the Technical University of Munich (TUM)

At the Technical University of Munich, the research project Timber Earth Slab (TES) investigated how mineral-bound earth material (with a binder from Oxara) and timber can be combined into a high-performance, resource-efficient floor system. This innovative construction system integrates the structural advantages of timber with the building-physics properties of mineral-bound earth material. Through the targeted interaction of these two materials, a unified and resource-efficient floor system for multi-storey timber construction is created.

Innovation with Depth: The multilayered rammed earth wall of the Walkeweg Auditorium, Basel

Specialised planning for Aequipe by Lehm Ton Erde and Lehmit With the new construction of the Walkeweg School auditorium in Basel, an innovative wall concept will soon be realized, based on the combination of timber and rammed earth: industrially prefabricated, structurally sophisticated, and architecturally expressive. The wall system, developed by Lehm Ton Erde, Lehmit, and Aequipe, stands as an exemplar of a new generation of resource-efficient, reversible, and aesthetically refined building envelopes made of earth and timber.

Hortus: Big-scale Earth and Timber

The Hortus project is more than just a building: it is proof that sustainable materials such as timber and earth can perform at scale. It was designed by Herzog & de Meuron and zpf and developed by Senn. Traditional building methods inspired low-carbon assemblies, regional resources were utilized, and a proposal for future-oriented construction was created. Yet sustainability means more than materials alone: it requires collaboration, innovation, and the courage to explore new paths together, as demonstrated by Hortus and the whole team involved.
