EIGNER Bauunternehmung

What EIGNER Bauunternehmung does

EIGNER Bauunternehmung GmbH is a family-owned German general contractor headquartered in Nördlingen, Bavaria, operating continuously since its founding by master builder Josef Eigner on 17 August 1912. The company delivers end-to-end construction services across eight practice areas — Industriebau, Hochbau, Ingenieurbau, Tiefbau, Altbausanierung, Holzbau/Dachdeckungen, and Schlüsselfertigbau — covering residential, commercial, industrial, infrastructure, and heritage restoration projects, primarily across Bavaria and Baden-Württemberg (southern Germany). Notable delivered projects include the FC Bayern München administrative building and underground garage (15,000 m³, 2007), the Zott corporate headquarters and parking structure in Mertingen (2020), the Jugend- und Familiengästehäuser youth hostel (2007/2010), and the Schwaben Präzision industrial facility (2024). Each project is run by a dedicated personal project manager from planning through turnkey handover under a Festpreisgarantie (fixed-price guarantee), with revenue generated transactionally per project.

The firm's underlying service stack combines traditional construction trades — including an in-house Zimmerei (carpentry) division retained from the 1937 expansion and a 25,000 m² Bauhof at Reutheweg — with a proprietary 3D concrete and clay printing division operated by R&D specialist Florian Greiser using Rhino and Grasshopper CAD/CAM. This 3D printing capability has produced the award-winning Concrete Lightweight Ceiling, which reduces CO2 emissions by 35% versus original planning and delivers 40% material and 42% CO2 savings against conventional concrete construction; it earned the Bundespreis Ecodesign 2025 from the Bundesumweltministerium/Umweltbundesamt and the 2023 Architekturpreis Beton. The 3D printing service is now offered to third-party construction firms and architects, with consumer-facing aesthetic concrete components sold via the EIGNER Betonmanufaktur sub-brand.

Commercially, EIGNER runs a sales-led go-to-market anchored on personal project management, word-of-mouth referrals from architects and engineering firms, and leadership roles in regional trade associations (Bauinnung Nordschwaben, Kreishandwerkerschaft Nordschwaben, Handwerkskammer für Schwaben, GÜB). Customer acquisition is supported by participation in trade fairs (BAU Munich, Swiss Bau Basel) and regional sports sponsorship (the named EIGNER Angels women's basketball team, TSV 1861 Nördlingen). The firm employs approximately 160 staff, holds a stack of certifications including Präqualifikation, TÜV SÜD §19 WHG, AMS Bau, Gütezeichen Beton, MHAVO suitability, and CrefoZert (top 1.7% of German companies for creditworthiness since 2014), and is led by three Geschäftsführer — Werner Luther, Günter Diethei, and Wolfram Uhl — joined the firm in 1985, 1989, and 1998 respectively, who each rose from internal ranks.

Revenue model

1. Construction Contracting: Core revenue stream from construction contracts as a general contractor (Generalunternehmen) providing comprehensive services from planning through turnkey handover. Covers Hochbau (residential/commercial), Tiefbau (infrastructure), Ingenieurbau (civil engineering), Industriebau, Altbausanierung, Holzbau/Dachdeckungen, and Schlüsselfertigbau (turnkey). Revenue is project-based, derived from fees on individual construction projects. Fixed-price guarantees are offered for turnkey projects.
2. Turnkey Construction (Schlüsselfertigbau): As a general contractor, EIGNER delivers complete building projects from A to Z including planning, structural work, interior finishing, and final handover. All economic, energy, and construction aspects are covered in a holistic concept. This integrated approach generates revenue as a bundled service package with fixed-price guarantees.
3. 3D Concrete Printing Services: EIGNER offers 3D concrete printing services to other construction firms and architectural offices for custom building components. Revenue is generated through printing fees for custom-designed components. The company also sells aesthetically designed concrete products for interior and garden applications to private customers through its associated entity EIGNER Betonmanufaktur.
