Wiehag

What Wiehag does

WIEHAG Holding GmbH is a fifth-generation, family-owned engineered timber construction company headquartered in Altheim, Upper Austria. Founded in 1849 by Josef Wiesner as a master carpentry workshop and now led by CEO Erich Wiesner, WIEHAG produces glued laminated timber (glulam / Brettschichtholz) bearing systems, custom connection systems, and roof/ceiling/wall elements at its Altheim campus. The company's vertically integrated offering spans engineering and consultation, prefabricated production, logistics, on-site installation, project management, and quality assurance, with a proprietary Special Truss System capable of supporting 250+ ton loads and handling components up to 30 meters in length.

WIEHAG serves two distinct customer streams. Its enterprise project business delivers large-scale hybrid timber buildings — including the 182-meter Atlassian Central Sydney tower, the World of Volvo hub in Gothenburg, the BESTSELLER Logistics Center West, the Mercedes-Benz SWI fast-charging park, and the upcoming Raiffeisenlandesbank Upper Austria headquarters — for commercial, institutional, and industrial clients across Europe, the UK, and Australia via offices in Germany, Spain, the UK, and Australia. A separate direct-to-consumer residential line, WIEHAG Bau GmbH, builds private homes and commercial structures in timber or brick in the Austrian regional market, supported by the WIEHAG WOODY online platform for ordering standard BSH products.

Revenue is project-based and negotiated per contract, with no public pricing. The firm has invested in a "Green Factory" energy self-sufficiency program combining a 3MW biomass combined heat and power plant with a 1MW rooftop photovoltaic system, and sources 100% PEFC-certified wood, with 16 of 20 sawmill suppliers based in Austria. The company has won the EY Entrepreneur Of The Year 2024 (Sustainability & Greentech), MIPIM 2026, and other industry awards, and is privately held with no institutional investors identified.
