Hundhausen

What Hundhausen does

Hundhausen is a fourth-generation, family-owned German construction group headquartered in Siegen-Weidenau, North Rhine-Westphalia, founded in 1898. The company operates from five locations across North Rhine-Westphalia, Thuringia and Saxony (Siegen-Weidenau HQ, Siegen-Eisern precast plant, Eisenach, Weida, Hilmersdorf) and employs approximately 330 people through its core entities W. Hundhausen Bauunternehmung GmbH and Hundhausen-Bau GmbH Eisenach.

Its service portfolio spans the full construction value chain: architectural and engineering planning (including BIM-based 3D modeling), turnkey general contracting (Schlüsselfertigbau) on fixed-price, fixed-date terms, structural and civil engineering, road and underground construction, hydraulic engineering and flood protection, specialized foundation engineering using Kelly drilling up to 35m, Deutsche Bahn-qualified railway track construction, and in-house manufactured precast reinforced concrete elements at the Siegen-Eisern plant. Technology adoption centers on BIM, Lean Construction, GPS surveying and machine control, mobile site hardware, and Plus-Energy building standards (DGNB Gold at the new 2025 HQ).

Hundhausen generates revenue primarily through project-based construction contracts awarded by German municipalities, Deutsche Bahn/DB InfraGO, and commercial enterprises across retail (Kaufland, REWE), automotive (Daimler, Porsche), industrial (Komatsu, Benteler, Veltins) and real estate development. Pricing is quote-based with multi-year fixed-price turnkey contracts. The go-to-market is direct enterprise field sales via the regional office network, supplemented by a PQ-Vergaben prequalification stack (DVGW, WHG, AMS Bau, Meisterhaft 5-Sterne, EcoVadis Bronze) that gates access to public tenders.
