Ingébois

What Ingébois does

Ingébois is a French independent engineering consultancy (bureau d'études) founded in 2007 and headquartered in Douai, Hauts-de-France. The firm specializes in structural engineering and building envelope design for timber construction, with technical depth in cross-laminated timber (CLT), glulam, timber-frame systems, passive building standards (Passivhaus), and biosourced/local wood supply chains. Its core deliverable is the structural design package — load calculations, connection detailing, fabrication drawings, and on-site construction supervision — supplemented by site diagnostics and custom consulting, plus autonomous steel engineering and concrete partner integration for multi-material projects.

The firm serves architects, general engineering firms, and project owners (maîtres d'ouvrage) across France, with documented projects spanning educational facilities, healthcare buildings, commercial real estate, sports and cultural venues, municipal public buildings, and infrastructure (notably a €7.5M Sanef highway canopy mandate). A portfolio of 38+ completed projects has accumulated since 2012, including Passivhaus- and BEPOS-certified buildings up to R+5 / 15,000 m², supported by a sustained record of regional and national wood construction awards.

Ingébois operates as a project-based professional services firm with a small team of approximately 10 people, including Partner and structural engineer Laurent LEPAUL. Revenue is generated through fee-for-service engagements quoted per project; pricing is not publicly disclosed. The firm has raised no external funding, remains privately held, and distributes services via direct client relationships, a project portfolio website, and LinkedIn — with no public AI, API, or platform layer.
