b-solution GmbH

What b-solution GmbH does

b-solution GmbH is an Austrian-headquartered (Hallein, Salzburg) construction technology company and wholly-owned subsidiary of the binderholz Group, founded in 2018 to industrialize multi-storey residential timber construction. The company offers the b_solution system, a configurable prefabricated solid wood construction kit using binderholz Brettsperrholz (BBS) cross-laminated timber for walls, ceilings, and roofs, supplemented by the proprietary b_box room module that integrates building services, a prefabricated bathroom, and structural load-bearing function into a single factory-finished unit. Projects can be configured by architects via a dedicated CAD plug-in that automatically generates a digital twin with cost calculation and production documentation, eliminating the need for specialized timber-construction expertise and enabling fixed price and schedule commitments.

The Hallein facility is engineered for serial production of components for up to 2,000 residential units per year under weather-independent conditions. The system is certified under Allgemeine Bauartgenehmigung aBG Z-9.1-935 and carries Ü/ÜA product certification monitored by Holzforschung Austria, plus PEFC chain-of-custody certification for the binderholz wood supply. b-solution generated measurable sustainability credentials, claiming approximately 27,000 tonnes of CO2-equivalent stored annually if 2,000 apartments are produced per year, an ESG narrative increasingly relevant to the cooperative and affordable housing market it targets.

Commercial activity centers on direct B2B project sales to housing cooperatives, project developers, public and nonprofit Bauherren, and architectural firms in the DACH region, complemented by ARGE-style joint ventures with construction partners such as Gustav Epple Bauunternehmung and a channel-locked procurement path via the GdW Framework Agreement for Serial and Modular Building 2.0. Named customers include wagnis eG (Augsburg), WGR Wohnungsgenossenschaft Reutlingen, GSP eG Berlin, Greenfields Buckow GmbH, Schlegel Concepts, Alpenländische Gemeinnützige Wohnbau, and WE Wohnungseigentum (Vienna), with marketing supported by trade fair presence (BAU, Expo Real), site visits, seminars, and a quarterly newsletter. Revenue is not publicly disclosed.

• BINDERHOLD (Binderholz Group): Parent group and broader binderholz portfolio (sawn timber, glulam, BBS CLT, pellets); comparable as the upstream supplier of BBS and as a mass-timber incumbent whose downstream offering overlaps with b-solution.

Regional players
