[2][3] The group has founded two design offices, Concept Bois Structure (CBS) in Paris and Concept Bois Technologie (CBT) in Lausanne, a wood prefabrication plant, Ecotim, created in 2005 in Savoie, and a construction supervision company, Lifteam, created in 2006.

[4][5] CBT is the continuation of a start-up company at the l'École polytechnique fédérale de Lausanne (EPFL) [6][7][8] aimed at transferring the research work carried out at the school by Jean-Luc Sandoz under the guidance of Julius Natterer, who was then head of the school's wood chair, into the practical field.

[11][12] The group designs numerous structural concepts such as frameworks and floors like Dalle O'Portune and D-Dalle.

It stands out for its ability to meet the highest demands in terms of performance, durability and aesthetics, and is thus recognized for its contribution to the realization of ambitious projects in the field of timber construction.

[20] The Group also has a presence in French Guiana, where it has been constructing buildings in local tropical materials, such as for CNES,[21] since 2015.
