What ALHO Systembau does

ALHO Systembau GmbH, headquartered in Friesenhagen, Germany, is a family-owned general contractor specializing in modular building construction. Founded in 1967 by Albert Holschbach, the company operates the proprietary ALHO Stahlmodulbauweise (steel modular construction system) and a complementary Holzhybridbauweise (wood-hybrid construction system), manufacturing 3D room modules in its own ALHO Raumfabrik factory with up to 90% prefabrication. Buildings of up to 6–7 floors are produced under controlled indoor conditions, then transported and assembled on-site with average on-site construction times of approximately 10–14 weeks, delivering schedule gains of roughly 70% versus conventional construction. The group also owns the FAGSI and ProContain brands for standardized mobile room containers, with a newly opened production hall in Morsbach-Lichtenberg in 2025.

The company's core technology rests on a free-span steel skeleton with non-load-bearing interior walls, enabling flexible reconfiguration, expansion, and dismantling. Modules are supported by in-house BIM/CAD planning, pre-approved Typenstatiken (type-calculated structural engineering), and an aBG F30 general building approval that accelerates permitting. ALHO holds the DGNB Mehrfach-Zertifikat in Gold for its entire building system, ISO 9001/45001/50001 certifications, RAL-GZ 613/619 quality marks, EN 1090-2 welding certification, and Blue Angel labeling. A partnership with Klöckner & Co SE supplies Nexigen® green steel (electric-arc-furnace, up to 100% scrap), reducing CO2 in steel content by approximately 30%.

Commercially, ALHO sells primarily through direct enterprise sales as a Generalunternehmer or Totalunternehmer on fixed-price (Pauschalpreis) contracts, serving public sector, healthcare, education, residential/social housing, office/administrative, and select federal customers across Germany, Belgium, Austria, Switzerland, Luxembourg, France, and the Netherlands. Minimum economic project size is approximately 500 sqm gross floor area. The group employs over 1,400 people across the Holschbach family-owned enterprise, with named customers including BImA (federal), LMU Klinikum München, Universität Bonn, Universität Augsburg, Klinikum Braunschweig, Wertachklinik Bobingen, VOLVO Dietze, Stadtwerke Wedel, and Familiesheim Mosbach eG. Pricing is project-specific and not publicly listed; the company cites verified 12% lower lifecycle costs versus conventional construction. Revenue is not publicly disclosed.

Revenue model

1. Modular Building Projects (Generalunternehmer): ALHO acts as a general contractor (Generalunternehmer) or total contractor (Totalunternehmer) delivering turnkey modular buildings at a fixed price (Pauschpreis). Revenue is generated on a project-by-project basis as one-time project revenue. The company provides all construction services including planning, production, transport, assembly, and finishing. The minimum economic building size is approximately 500 sqm gross floor area (BGF).
2. Container Rental and Sales (FAGSI/ProContain): The FAGSI brand, part of the ALHO Group, rents and sells standardized mobile room containers (ProContain) for temporary space needs in the construction industry and other sectors. This represents a separate revenue stream from the modular building business.
3. Professional Services (Planning & Architecture): When acting as Totalunternehmer, ALHO provides architectural planning, building permit planning, and specialized engineering (TGA, statics, fire protection, building physics, sustainability certification). Planning services may be included in the turnkey package or offered separately.
