What holzius does

holzius S.r.l. G.m.b.H. is an Italian-headquartered manufacturer of prefabricated solid timber building elements, based in Laas/Lasa in South Tyrol (VAT IT02454290217), and operating as a subsidiary of the Rubner Holding AG timber-construction conglomerate. Founded in 2005 with 101–250 employees, the company designs and produces glue-free and metal-free solid wood wall, ceiling, roof, and beam elements for custom-built residential, hospitality, public, and commercial buildings across Italy, Germany, and Austria.

The underlying technology is a patented connection system using precision-milled tongue-and-groove joints (Gratleiste) that joins individual solid wood boards without adhesives or metal fasteners, while preserving the natural growth direction of the tree. The product portfolio is anchored on Vollholz-Wandelemente (wall elements), Schallschutzwände (soundproof walls), Vollholz-Decken- und Dachelemente (ceiling/roof elements), and Vollholz-Zahnbalkenträger (toothed beam carriers), with add-on modules including Vollholz-Akustikdecke (acoustic ceiling), Klimafräsungen (precision-milled climate channels for radiant heating), and Holz-Beton-Verbund-Decke (wood-concrete composite ceilings).

Revenue is generated on a custom project-quotation basis, with each engagement treated as a one-time license-style project involving design consultation, prefabricated element production at the Laas facility, and on-site assembly delivered through a channel network of regional carpentry partners including Holz Pabst, Zimmerei Fleischmann, and Holzbau Brida. Go-to-market combines direct sales with event-driven demand generation (Klimahouse trade fair, cantiere aperto open-site events, CPD-accredited webinars for architects) and architect/planner referral partnerships. Reference projects span the 5-star DAS GERSTL Family Retreat (1,000+ m³ of timber, ~820 t CO₂ stored), the Stelvio National Park Val Martello Parkhütte at 1,990 m altitude, and individual custom homes in Austria and South Tyrol.

Revenue model

1. Custom solid timber homes: holzius designs and produces custom, individually planned solid timber houses. Each home is a unique single piece (Unikat) tailored to the specific wishes of the residents. Revenue is generated through the sale of complete timber home projects including design consultation, prefabricated elements, and assembly support.
2. Prefabricated solid timber building elements: holzius sells individual building elements including wall panels, ceiling/roof elements, acoustic ceilings, climate-milled elements, toothed beams, and wood-concrete composite floors to architects, builders, and construction partners. Products are sold as standalone components for integration into broader construction projects.

Core offering

holzius designs and produces prefabricated, glue-free and metal-free solid timber (Vollholz) building elements — including wall panels, ceiling and roof elements, soundproof walls, toothed beam carriers, wood-concrete composite floors, acoustic ceilings, and climate-milled elements — and delivers complete custom-designed solid timber house shells and construction projects across Italy, Austria, and Germany. Elements are joined via a patented precision-milled tongue-and-groove (Gratleiste) system, with wood assembled following the tree's natural growth direction.

Product overview

holzius is a solid wood construction company specializing in glue-free and metal-free solid wood building systems. The product portfolio centers on structural building elements including wall elements (Vollholz-Wandelemente), soundproof walls (holzius-Schallschutzwände), ceiling and roof elements (Vollholz-Decken- und Dachelemente), toothed beam carriers (Vollholz-Zahnbalkenträger), and wood-concrete composite ceilings (Holz-Beton-Verbund-Decke). These core structural products are complemented by add-on modules such as acoustic ceilings (Vollholz-Akustikdecke) and climate carvings (Klimafräsungen) for radiant heating integration. All elements use a patented interlocking connection system with ridge strips (Gratleisten) rather than adhesives or metal fasteners, and are manufactured from untreated solid wood (typically spruce, larch, and Swiss stone pine) following the natural growth direction of the tree.
