What Sohm HolzBautechnik does
Sohm HolzBautechnik GmbH is a privately held, family-owned engineered-timber construction company founded in 1990 in Alberschwende, Vorarlberg, Austria. The company designs, fabricates, and erects mass-timber buildings using its patented DiagonalDübelholz (DD) system, in which kiln-dried fir, spruce, and white-fir lamellas are connected by diagonally pressed hardwood dowels and wave profiling rather than metallic fasteners, yielding a glued content of just 0.05% (roughly one-tenth of cross-laminated timber). Sohm serves residential, commercial, agricultural, public-sector, and special-construction clients across Austria, Germany, Switzerland, and Liechtenstein, operating three locations (Alberschwende HQ, Sohm AG Schweiz in Widnau, and Sohm Holzbau in Bellenberg, the rebranded former Gamper Holzbau acquired in 2023), with group headcount reported at 105 including 17 apprentice carpenters.
The company's core product stack comprises DiagonalDübelholz flat mass-timber elements (walls, ceilings, roofs) in dimensions up to 15 m length and 80–260 mm thickness; SohmVollHolz finger-jointed lamellas produced in-house at its own sawmill; and complementary BSH (glulam) and 3-layer plate products. The system carries European Technical Assessment (ETA) certification, REI90/REI60/EI60 fire-resistance ratings, and ISO 354 acoustic-performance certification for Aku-Top ceiling variants, enabling use in multi-story timber construction. Notable execution includes the LifeCycleTower ONE (8 floors in 8 days with 5 workers), the Seezeitlodge sauna village, the VAUDE production hall, multiple Sutterlüty retail projects, and award-winning civic and educational buildings.
Sohm makes money through two complementary streams: turnkey general-contractor construction services (one-time project revenue across all building categories) and direct wholesale sales of DiagonalDübelholz elements and prefabricated wall/ceiling elements to commercial customers at quote-based pricing. Go-to-market is entirely direct, sales-led, and relationship-driven, relying on Instagram presence, a downloadable project reference catalog, and trade-award recognition rather than digital or marketplace channels. The customer mix is diversified across enterprise, mid-market, SMB, and government segments with no single-customer concentration, supported by 300+ completed projects across all categories.
