What KLEUSBERG does

KLEUSBERG is a German family-owned modular construction company founded in 1948, headquartered in Wissen, Germany. It operates three core business areas: Modulares Bauen (turnkey modular buildings with up to 95% factory pre-fabrication), Mobile Raumsysteme (temporary container-based buildings for rent or purchase), and Industrie-Räume (room-in-room systems installed within existing production facilities). Its customer base spans public-sector education buyers (school authorities, municipal building companies), healthcare providers (hospitals, research labs), and industrial enterprises (manufacturers, logistics operators) primarily in Germany, with limited reach into Austria.

The company's underlying technology combines steel-frame modular construction with a proprietary Holz-Hybrid (wood-hybrid) system that pairs structural steel frames with cross-laminated timber (Brettsperrholz) walls, floors, and ceilings, achieving up to 96% recyclability. Its flagship product platform, the Schulbaukasten, offers 44 pre-configured modular segments enabling schools to be digitally configured and delivered in 10-12 weeks. Production is distributed across at least four dedicated manufacturing facilities (Werk 1 Wissen, Werk 2 Kabelsketal-Dölbau, Werk 3 Remseck, Werk 6 Gröbers, Werk 7 Morsbach), supported by regional sales offices in Hamburg, Berlin, Düsseldorf, München, Frankfurt, Olpe, and St. Marien (Austria).

KLEUSBERG generates revenue through three primary streams: (1) turnkey modular construction projects billed as one-time general-contractor (Totalübernehmer) fees, (2) sale and rental of mobile room systems and container-based solutions, and (3) construction consulting and project management services embedded in the turnkey offering. The firm sells primarily through direct enterprise field sales to institutional clients, supplemented by public-sector tendering, regional sales offices, expert consultation appointments booked via its website, and presence at trade events such as SCHULBAU Frankfurt and the Heinze ArchitekTOUR. No public pricing is disclosed, but the Schulbaukasten is marketed with a guaranteed fixed price (Festpreis garantiert), and KfW energy-efficiency subsidies are referenced.

Direct peers

• ALHO Group: German family-owned modular construction company producing steel-frame modular buildings for schools, healthcare, offices, and housing. Closest direct competitor to KLEUSBERG in the German Mittelstand modular market, with overlapping product portfolio and customer segments.
• SÄBU Holzbau und Systembau: German manufacturer of modular timber-frame and steel-frame buildings for educational, administrative and residential use. Comparable mid-sized German competitor with overlapping public-sector customer profile.
• Cadolto Modulbau: German modular construction specialist, particularly strong in healthcare and laboratory buildings. Highly comparable to KLEUSBERG's UKB Universitätsklinikum Bonn-style projects, with similar turnkey delivery model and factory prefabrication.
• Containex: Austrian-headquartered provider of container-based modular space solutions (Containerx), overlapping with KLEUSBERG's Mobile Raumsysteme business. Particularly comparable in DACH-region rental and temporary-building markets.
• KOMA Modular: Polish-based modular construction company with growing European footprint in schools, offices and residential. Comparable product offering and turnkey approach, with a more cost-competitive cost base from Polish production.

Broad incumbents

• Algeco (Modulaire Group): European leader in modular space rental and sales, explicitly named alongside KLEUSBERG as a European modular construction peer. Larger scale, broader geographic footprint, and stronger recurring-rental revenue model make it a broad incumbent rather than a pure direct competitor.
• Portakabin: UK-headquartered European modular building specialist with strong healthcare, education and office verticals. Comparable customer segments and turnkey delivery model, but with broader geographic reach and a more developed rental fleet.
• Laing O'Rourke: UK-headquartered international construction firm named in industry lists alongside KLEUSBERG as a European modular construction peer. Substantially larger scale and broader scope, competing on larger institutional and infrastructure tenders.
• Skanska: Swedish-headquartered global construction and development company cited as a European modular construction peer alongside KLEUSBERG. Operates modular construction as part of a much broader infrastructure and real-estate portfolio.

Regional players

• Wolf System: German-Austrian timber construction specialist with modular building capabilities, particularly in agricultural, industrial, and energy sectors. Comparable in regional timber-hybrid modular construction and overlaps with KLEUSBERG's Holz-Hybrid offering.
