Training course & Discovery days - Raw earth construction

From May 25 to 28, 2021 Atelier LUMA in collaboration with BC Materials organized a series of workshops around raw earth building materials and techniques. The workshops took place in the Parc des Ateliers, in the framework of the rehabilitation of the building Magasin Électrique.

The first course Building with Raw Earth and the discovery days allowed participants to learn about and experiment with raw earth, to obtain building materials adapted to the economic and ecological challenges of our time.

Day 1 - Tuesday, May 25, 2021: Research and development of raw earth

Day 2 - Wednesday, May 26, 2021: Pisé

Day 3 - Thursday, May 27, 2021: Raw earth brick

Day 4 - Friday May 28, 2021: Clay plaster

From autumn 2021, you will have the possibility to improve your knowledge with 5-day courses on this building material.

This training is organized with the Pôle Culture & Patrimoines which allows you to benefit from your training rights.

This training course and the discovery days are part of the Magasin Électrique project.

Developed in collaboration with BC Architects and Assemble, the rehabilitation of the Magasin Électrique building implements design strategies and materials adapted to architectural projects built for uncertain futures.

By mapping the Arles region, the Magasin Electrique team has identified a wide variety of resources and know-how in order to reconstitute building materials based upon the principles of non-extractivist architecture.


BC Materials

BC materials is a cooperative company producing building materials based on local resources and more specifically raw earth. The BC team engages in experimental projects through which they design bioregional and circular architecture, study educational and construction processes and produce new materials using local waste streams such as excavated earth.

BC materials was commissioned by Atelier Luma to create and produce materials from local resources for the construction of their future workspace in the Parc des Ateliers.

L’Atelier Kara

Founded in August 2017 by architect Timur Ersen, Atelier Kara specializes in pisé craftsmanship. Pisé is a very old construction method where raw earth is compacted in a formwork; the Atelier makes works of environmental and architectural quality. It develops new pisé construction processes, improves tools, invents and experiments with new floor and wall finishes.


Architect and artist, Isabella Breda has dedicated herself since 2006 to developing works in raw clay. She specializes in artistic renderings in interior architecture and takes advantage of her interventions to create ephemeral installations. She thinks of the architectural surface as a skin, a membrane that filters the data between the interior and the exterior and sublimates, through her work, the aesthetic and artistic value of the earth material. To her, space is a fullness that welcomes the paths of those who cross it, makes visible the coherence of the signs left by the different passages, feels the history, the life, or does not feel at all. In the earth, she leaves her imprint, suggests her passage, while giving the material the opportunity to express itself.

Briques Technic Concept

The company Briques Technic Concept is mainly born from an ethical will, from a desire to protect the environment. We are on earth to live, limiting as much as possible our impact on nature. (The sharing of knowledge and the establishment of a fair market is at the source of our concerns.)

The company was created in 2012, following the meeting between a man and a material. It is a company that is constantly innovating, both on the product and on the production processes. We are part of a process of continuous improvement and perseverance to democratize the use of the material and improve its national recognition and normative.
