Bonson – Collective

Located in Bonson (Loire), the residential development Le Green is recognised as the first multi-family building in France constructed with TimberROC wood-based concrete. The project embodies a commitment to combining environmental performance, occupant comfort, and exemplary construction quality. It forms part of the transformation of the station district and stands as a showcase for sustainable, bio-based housing.

Highlights :

  • Structural load-bearing walls (CS2) prefabricated in wood-based concrete
  • Wall-to-slab connection through concrete reinforcement
  • Off-site production and on-site installation by R-Technologies, ensuring speed and execution quality.
  • France’s first wood-based concrete apartment block
  • Strong example of innovation and cooperation between developer, social landlord and local authority
  • Promoting sustainable construction with high environmental value
  • Significantly reduced carbon footprint and natural summer comfort
