What S. Müller Holzbau AG does

S. Müller Holzbau AG is a privately held Swiss timber construction company headquartered in Wil, Canton St. Gallen, operating as a full-service "Ostschweizer Gesamtdienstleister" (Eastern Swiss full-service provider) for residential and commercial timber buildings. Founded in 2008 as S. Müller Holzbau GmbH, the company delivers an integrated end-to-end service spanning architecture and planning, building permit submission, in-house timber element production using a 100-meter CNC-controlled production line with two element robots, on-site assembly, facades, interior finishing, windows and doors, and post-handover services. Its core technology centres on prefabricated timber element construction (Holzelementbau), which shortens on-site construction time and enables millimetre-precise, large-format component manufacturing for complex architectural projects.

The company serves three primary customer segments: private homeowners (the dominant segment, ranging from single-family home builders to multi-family residential developers), B2B partners including contractors, architects and other timber builders (who purchase prefabricated elements and CNC-machined components), and commercial/institutional clients (with reference projects for Lidl Schweiz, AXA, SGKB and the Zurich Film Festival). Revenue is generated primarily through per-project construction contracts, supplemented by B2B hardware sales of prefabricated timber elements and property development (e.g., the WOLFIKON95 row houses marketed via the Von Holz AG platform). The business model is sales-led and consultative, with no reseller or distributor network: all projects are acquired and executed by the company's own architecture, production and construction teams. Pricing is quote-based in CHF, non-publicly disclosed, with payment terms governed by company AGB.

As of 2023 the company employed approximately 100 people (up from 15 at founding), operates a wholly-owned subsidiary VierD AG (mobile room concepts / event construction, founded 2016), and in 2025 moved into a newly completed production and office campus at Sirnacherstrasse 6a in Wil. Geographic focus is Eastern Switzerland, with projects executed across the cantons of St. Gallen, Thurgau, Zürich, Glarus and Aargau.

Müller Holzbau AG is a full-service timber construction provider delivering complete building projects from initial concept and architectural planning through prefabricated timber element production, CNC machining, on-site assembly, facades, interior finishing, windows and doors, and post-handover services. The company also sells prefabricated wood elements, CNC-machined components, and engineering services to B2B partners such as contractors, architects, and timber builders.

Product overview
