ERNE

What ERNE does

ERNE AG Holzbau is a Swiss timber construction company founded in 1906 and headquartered in Stein AG, Switzerland, operating as the timber-construction arm of the privately held ERNE Gruppe (800+ employees across the group). The company designs, engineers, prefabricates, and assembles sustainable timber and hybrid building systems — including modular timber construction (Holz-Modulbau), timber system construction (Holz-Systembau), hybrid timber-concrete/steel/rammed-earth structures (Holz-Hybridbau), parametric facades, wood-metal window systems, and the proprietary SupraFloor® and SupraFloor® ecoboost2 wood-concrete composite floor platforms — for public institutions, residential developers, commercial real estate investors, healthcare providers, and research facilities.

The company operates as a total contractor (Totalunternehmer) under a project-based one-time contract model, delivering the full lifecycle from design through on-site assembly using its own industrial prefabrication facilities in Stein AG (Switzerland) and Sinsheim (Germany), supported by an in-house joinery and interior-fitout workshop. Revenue is generated through construction contracts, sale of prefabricated building systems, integrated joinery and service/maintenance work, and rental/sale of temporary modular buildings. Go-to-market is direct enterprise sales — tenders, direct invitations, and repeat institutional clients — in Switzerland and Germany, with a regional office in Penthalaz serving French-speaking Switzerland and a wholly-owned German subsidiary, ERNE GmbH, headquartered in Wiehl. Within the ERNE Gruppe, ERNE AG Holzbau is paired with sister company ERNE AG Bauunternehmung (concrete/masonry) to deliver full-stack building solutions from a single source.

Revenue model

1. Construction Contracts (Totalunternehmer / TU): ERNE acts as a total contractor (Totalunternehmer) and general contractor for building projects. Revenue is earned through project-based construction contracts covering the full project lifecycle: from design and engineering through to prefabrication, on-site assembly, and handover. The company also offers partial contracts (building systems, facades, windows, modular units) and operates as total performance competition (Gesamtleistungswettbewerb) partner.
2. Building Systems and Prefabricated Components: Sale and installation of proprietary building systems including timber-hybrid structures, timber modular units, facades, and window systems (Holz-Metallfenster). These are sold as standalone products or as part of larger construction contracts.
3. Integrated Services (Joinery, Interior, Service-Dienst): Additional revenue streams from joinery and interior fitting (Schreinerei, Innenausbau), renovation, room-in-room systems, and ongoing service and maintenance (Service-Dienst, Wartung, Instandsetzung, Umbau).
4. Temporary Modular Buildings: Rental and sale of temporary modular building solutions in Switzerland and Germany, with available modular units listed on the company website.

Core offering

ERNE AG Holzbau is a Swiss timber-construction company that designs, prefabricates, and assembles sustainable building envelope, facade, window, and interior-fit-out solutions for public, commercial, and residential projects. The company executes complex timber, wood-hybrid (SupraFloor®), and modular construction projects—often acting as total contractor (Totalunternehmer)—serving clients in Switzerland and Germany, and combines 110+ years of timber-craft expertise with industrial digital fabrication.

Product overview

ERNE AG Holzbau is a Swiss timber construction company offering a comprehensive portfolio of construction systems and technologies for industrial and commercial building projects. The portfolio is organized around core construction system products — Holz-Hybridbau (hybrid timber construction), Holz-Modulbau (modular timber), Holz-Systembau (system timber construction), Aufstockungen (building extensions), Fassaden (facades), and Fenstersysteme (windows) — supported by integrated service offerings including Gesamtleistungen (total contractor services), Schreinerei/Innenausbau (joinery and interior fit-out), and a Service-Dienst (maintenance and conversion). These systems are enabled by a suite of construction technologies: Digitale Fertigung (digital fabrication), Parametrische Fassaden (parametric facades), Stahl-Leichtbau (steel lightweight construction), and the SupraFloor® and SupraFloor® ecoboost2 wood-concrete composite floor systems. Additionally, ERNE offers Temporäre Räume (temporary modular spaces) for rapid space needs. The company operates as a total contractor (TU) delivering from design through assembly, with its own industrial prefabrication facilities ensuring precision and efficiency.

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Stora Enso Building Solutions: Division of Finnish-Sweded pulp-and-paper-turned-CLT giant supplying CLT panels and building systems across Europe. Indirectly comparable to ERNE as an upstream CLT supplier and increasingly active in full timber building solutions, with significantly greater scale and capital base.
• Implenia: Switzerland's largest construction and real estate services group, operating across general contracting, civil engineering, and real estate development. Competes with ERNE on large Swiss public/institutional total-contractor mandates, with broader portfolio but less specialization in timber construction.

Direct peers

• ALHO Systembau: German modular construction company producing prefabricated steel/timber modular buildings for schools, healthcare, offices, and public administration. Directly comparable to ERNE's Holz-Modulbau and temporary space offerings, with a stronger German footprint and broader material range.
• Blumer Lehmann: Swiss timber construction company with a long heritage, operating in modular timber, hybrid structures, and total contractor services. Most direct domestic peer to ERNE, competing in the same Swiss institutional and residential timber markets with comparable proprietary systems and prefabrication capabilities.
• KLEUSBERG GmbH & Co. KG: German modular construction specialist focused on public-sector buildings (schools, administrative buildings, kindergartens). Comparable to ERNE on the institutional/cantonal customer segment and modular project delivery model, primarily competing in Germany.
• WIEHAG GmbH: Austrian timber construction specialist with expertise in hybrid timber-concrete-steel structures and large-scale engineered timber buildings (including sports halls and industrial facilities). Directly comparable to ERNE on hybrid construction technology and total contractor delivery of complex timber projects.
• HESS TIMBER: German specialist for timber engineering, glulam structures, and complex timber roof/facade construction. Comparable to ERNE on engineered timber components and large-span timber solutions, competing for similar public and commercial projects in the DACH region.
• SchwörerHaus: German timber construction and modular home manufacturer offering prefabricated timber buildings for residential, commercial, and public-sector clients. Directly comparable to ERNE's Holz-Modulbau and Holz-Systembau product lines, with a stronger residential focus and significant German market presence.
• Cadolto Modulbau: German modular construction company specializing in factory-built modules for hospitals, schools, data centers, and laboratories. Directly comparable to ERNE's Holz-Modulbau and modular project execution, with similar factory-driven, speed-of-delivery value proposition in the DACH public-sector market.

Emerging players

• Binderholz: Austrian family-owned timber group producing CLT/glulam and engineered wood, increasingly moving downstream into full timber construction services. Comparable to ERNE on timber system technology and hybrid construction, though larger scale and more vertically integrated in raw material production.
