GUSTAVE

What GUSTAVE does

GUSTAVE – INGENIEUR BOIS is a French structural engineering firm headquartered in Bonneville, Haute-Savoie, operating as an SAS with €40,000 share capital and four offices (Paris, Lyon, Toulouse, plus the Haute-Savoie HQ). The firm specializes exclusively in timber construction, with technical depth in CLT (cross-laminated timber), glulam (lamellé-collé), and hybrid wood-steel-concrete structures. GUSTAVE executes three core professional service lines: Maîtrise d'œuvre (engineering and project management across ESQ/APS/APD/PRO/DCE and ACT/VISA/DET/AOR phases), Expertises (structural diagnostics, pathology analysis, and judicial expertise as sapiteur for insurers and courts), and Plans d'EXE / Plans d'atelier (execution and workshop plans plus 3D modeling for timber contractors).

Commercially, GUSTAVE generates revenue on a project-based professional-services basis — typically as a percentage of construction cost or fixed fees per engagement, with pricing not publicly disclosed. Its go-to-market is consultative, field-based B2B sales targeting architects (e.g., Moreau Kusunoki, PCA-STREAM, AUM/Keops, NP2F), property developers (EMERIGE, COVIVIO, Pichet/Legendre), and public-sector clients (SOLIDEO, SNCF Réseau, Région Auvergne-Rhône-Alpes, Etablissement Public Reconstruction Notre-Dame). The firm is led by five named associates (Antoine Roux as Président, plus Boyer, Clamaron, Bron, Cagnin) with a roster of engineers drawn from ENSTIB, ESB, Polytech, CHEC, INSA Lyon, ESTP, and ECAM La Salle.

Visible project scale ranges from €320K mountain refuges and pedestrian bridges to the Paris 2024 Olympic Village (16 buildings, 24,600 m², with €15M of wood works inside an €88M total). Landmark projects include Tour P13 Le Berlier — the tallest timber building in France at 56m, delivered without an ATEX — and AMO engagement on the Notre-Dame de Paris timber reconstruction feasibility. The firm has accumulated six industry awards since 2019 (BATIACTU Trophée, FIBOIS regional and departmental awards, CADWORK competition) and operates with roughly 14 team members total. No external investors, PE/VC backing, or acquisitive activity is evidenced.

Direct peers

• Bollinger + Grohmann: Germany-based structural engineering consultancy with a strong timber and hybrid structures practice serving architects on complex buildings. Comparable to Gustave as a specialist engineering consultancy embedded in award-winning architectural projects (Olympic Village analog: complex public and cultural buildings).
• Pirmin Jung Ingenieure: Swiss specialist timber engineering firm offering structural design, feasibility studies and detailed execution planning for large-scale timber and hybrid projects. Directly comparable to Gustave on technical scope (CLT/glulam expertise) and project-based B2B service model.
• Simonin SAS: French wood construction firm combining structural engineering, prefabrication and installation of glulam/CLT buildings. Operates in the same French market and project types as Gustave, with overlap on mid-rise timber and public infrastructure projects.
• Schlaich Bergermann Partner (SBP): German structural engineering consultancy renowned for innovative timber, hybrid and long-span structures, including heritage work. Comparable to Gustave on technical sophistication, signature architectural projects and presence in landmark European public commissions.
• Arbonis (Vinci Construction): French subsidiary of Vinci specializing in wood structure design-build for residential and public buildings, including timber engineering and prefabricated wood frames. Closest French competitor to Gustave, with comparable CLT/glulam capabilities but a more vertically integrated contractor model.
• Timbatec Holzbauingenieure: Swiss timber engineering consultancy providing structural engineering, 3D modeling and workshop plans for CLT and glulam projects across Europe. Closest analog to Gustave in terms of service offering (engineering + execution plans) and target clients (architects, developers, public bodies pursuing mass-timber buildings).
• HESS TIMBER: German engineered-timber specialist delivering structural design, fabrication and assembly of large-span glulam and hybrid timber structures. Comparable to Gustave on complex structural engineering scope for landmark buildings (stadiums, public facilities, bridges).

Broad incumbents

• WIEHAG GmbH: Austrian engineered-timber constructor combining structural engineering, prefabrication and assembly for large timber buildings (often sports, commercial, public). Broader and more industrial than Gustave but competes for the same flagship architectural timber projects.
• Stora Enso Building Solutions: Pan-European CLT/glulam manufacturer offering design-assist, technical advisory and engineered wood products used on the same projects Gustave services. Adjacent rather than directly competing: a CLT supplier whose technical support overlaps with specialty timber consultancies.

Others

• ITECH (École d'ingénieurs) spin-outs / SNBC Bois consultancy ecosystem: Adjacent ecosystem of timber engineering consultancies, R&D labs and industry bodies (including France Bois 2024) that Gustave partners with and competes against on public sector timber mandates. Relevant context for understanding the French timber engineering competitive set rather than a single direct rival.
