Wenger Holzbau AG

What Wenger Holzbau AG does

Wenger Holzbau AG is a Swiss timber construction specialist headquartered in Unterseen, Canton of Bern, operating through two production facilities (Unterseen headquarters founded 1954 and Steffisburg branch opened 1994) with a team of 70-80 employees supplemented by an annual intake of 6 apprentices. The company operates across four core service divisions: Ingenieurholzbau (engineering timber construction), Zimmereiarbeiten/Umbau/Renovationen (carpentry, conversions, renovations), Holzsystem- und Fassadenbau (prefabricated wood systems and facade construction), and Schallschutz (EMPA-tested sound barrier walls made from Swiss spruce/fir with certified >32dB performance).

The business runs a sales-led, project-based model with direct client engagement spanning consultation, structural planning, in-house CNC-based prefabrication (Hundegger ROBOT-Drive cutting system), and on-site assembly by dedicated project managers. Customers include public-sector entities (cantonal and municipal infrastructure, schools, hospitals), commercial clients (BLS railway infrastructure, enterprises), and individual homeowners across German-speaking Switzerland. Sound barriers are produced using vacuum-pressure-impregnated Swiss timber sourced via partnership with Imprägnierwerk Willisau, with an estimated 50-year product lifespan.

Wenger Holzbau AG is privately held, family-rooted (transitioned from founder Paul Wenger to Markus Wenger to current CEO Alexander Rindlisbacher in 2018), Minergie-certified, and a certified apprenticeship training company (Lehrbetrieb). In 2024 the firm spun off its joinery activities into W-Werk AG (Marco Wüst) and acquired new CNC capacity, while continuing to celebrate its 70+30-year milestone. The company carries no external institutional investors and operates exclusively in the domestic Swiss market.
