Larch was used to integrate the building into its natural environment while also responding to time constraints: the site had to be completed within only six months. The structural framework, wall panels and siding were factory-manufactured and quickly assembled on-site.

The use of bio-based materials and the implementation of certain technical solutions also demonstrated STUDIOS’ ongoing commitment to sustainable, virtuous architecture.

A major element in the construction, wood is also highlighted within. Designed using warm materials, with a focus on energy efficiency and the comfort of users, Boréal is a three-level structure housing technical facilities, offices and common areas for the site’s operational staff.

Distributed around a large skylighted stairwell, the different spaces communicate between themselves and the outdoors.

Wood is also omnipresent throughout the interior of the building, where exposed cross-laminated timber panels and glued laminated framework bring warmth and harmony to the whole.

Boreal's environmental approach :

• A bioclimatic design
  - Different treatment of facades according to their climatic orientation
  - Natural ventilation
  - Green roof
  - Discreet integration into the site
• An off-site prefabricated timber construction
  - Glued laminated timber frame
  - Wooden floor / posts
  - Facades in CLT
  - Larch exterior cladding
• An architectural concept in favour for reversibility and flexibility
  - Removable floor
  - Free post trays
• Bio-based and local materials:
  - European wood
  - Soft linen-based flooring
  - Wood wool insulation
  - Wooden mill work
• Optimized energy performance and carbon footprint
  - EFFINERGIE + targeted
  - CEP = 60 kWh / m² / year
  - Dry sector worksite
