Charpente Concept

What Charpente Concept does

Charpente Concept SA is a Swiss wood engineering and design firm founded in 1991 by Thomas Büchi and headquartered in Perly-Certoux (Geneva canton). The firm provides specialized engineering services for timber construction, including static calculations, structural dimensioning, execution plans, fire safety engineering (certified at AEAI Q3 expert level), technical expertise and diagnostics using the Sylvatest wood analysis system, and general construction management. Through its sister company REALIZ SA, Charpente Concept also delivers turnkey general contracting for energy-positive buildings. The firm's client base spans public institutions (CERN, OMPI/WIPO, CICR, Confédération Suisse), heritage and high-altitude projects (Notre-Dame de Paris diagnostic, Refuge du Goûter at 3,850m), private developers, and architects requiring complex wood structures.

The firm's technology stack combines proprietary systems — Lucido active facades coupled with photovoltaic cells and heat pumps, Resix metal-rod epoxy assembly methods, the Tensairity Airlight inflatable membrane bridge system, and the BISS self-service engineering module with 72-hour delivery — with certified domain expertise in sustainable, locally sourced timber construction. Projects range from villas and residential buildings (e.g., Aulne Nuovo THPE-certified apartments) to extreme-cantilever public buildings (OMPI's 34m cantilever conference room, the first worldwide for wood structure).

Revenue is generated primarily through project-based professional services contracts won via direct client relationships and competitive tendering, with supplementary income from the hourly-rate BISS self-service module and retail book sales (Le Bois Ma Passion at CHF 34, Fragments de lumière at CHF 39). The firm operates four offices across western Switzerland and Haute-Savoie, France, and has executed projects in Switzerland, France, Luxembourg, Norway, Gabon, the French West Indies, and the USA. The company is privately held, founder-controlled, with no external institutional capital disclosed.
