What Klaus does

KLAUS Gruppe is a family-owned German construction group headquartered in Augsburg, Bavaria, operating through five wholly-owned subsidiaries: KLAUS Wohnbau (residential development), KLAUS Hoch + Tiefbau (building construction, civil engineering, concrete prefabrication, raw material extraction), ECKLE Tiefbau and HOLL Tiefbau (regional civil engineering and road construction), and recycling+ GmbH (construction material recycling). The group serves private residential customers, commercial/industrial clients, and public-sector/municipal authorities primarily across the Augsburg, Munich, Ulm, and surrounding Bavarian corridor regions. The legal entity is structured as KLAUS GmbH & Co. KG, a German limited partnership, with KLAUS Geschäftsführungs-GmbH as general partner and Dipl.-Ing. (FH) Jörg Klaus as Managing Director (Geschäftsführer).

The company's core technology stack centers on physical construction execution rather than software, anchored by vertically integrated capabilities spanning raw material extraction (own gravel pits in Königsbrunn and Lösau), in-house concrete prefabrication (~12,000 customized components annually at the Kissing facility, including stairs, balconies, facades, and structural elements), and full-service construction delivery. A distinctive proprietary offering is the DINO® Dachhebesystem (Roof Lifting System), a patented hydraulic technology developed since 1992 that lifts existing roof structures to enable attic conversion or floor expansion without demolition, with over 1,500 completed installations including heritage-protected buildings. KLAUS Hoch + Tiefbau additionally holds TÜV SÜD certification as a specialist firm under §19 I WHG (German Water Resources Act) for handling water-hazardous substances.

The revenue model is project-based professional services plus hardware sales (prefabricated concrete elements and raw construction materials), with no publicly disclosed pricing. GTM is sales-led and regionally anchored, with each subsidiary operating in defined geographic territories and customer segments (private, commercial, public), acquired via direct outreach, referrals, project tenders, and regional market presence. Distribution runs through dedicated subsidiary websites, Instagram channels for KLAUS Hoch + Tiefbau and KLAUS Wohnbau, and a recruitment-focused careers portal. Marketing emphasizes the multi-generation family-business identity, regional roots, and integrated "all construction services under one roof" value proposition.

Broad incumbents

• ZECH Bau GmbH: Mid-sized German construction group providing building construction, civil engineering and real estate development across multiple regions. Comparable in mixed residential/commercial/public-sector project delivery but with broader geographic footprint than KLAUS.
• BAM Deutschland AG: German subsidiary of Royal BAM Group delivering building construction and civil engineering projects nationally. Overlaps with KLAUS Hoch + Tiefbau on public infrastructure and commercial building scope but at significantly larger scale.
• GOLDBECK GmbH: Germany's leading prefab commercial/industrial building specialist with systemized construction and own concrete production. Comparable in prefab concrete manufacturing but operates nationally at much larger scale, serving primarily commercial rather than mixed residential segments.

Direct peers

• Köster GmbH: German Mittelstand general contractor covering building construction, civil engineering and turnkey projects for public and private clients. Comparable in scope, customer mix (private + public sector), and integrated regional delivery model.
• Leonhard Weiss GmbH & Co. KG: Mid-sized German Mittelstand construction group offering building construction, civil engineering, road construction and turnkey project delivery. Closely comparable as a family-owned full-service contractor with comparable scale, structure (KG), and integrated service model across residential, commercial and public-sector work.
• WOLFF & MÜLLER Holding GmbH & Co. KG: Family-owned German construction group with divisions in building construction, civil engineering and raw materials, comparable in Mittelstand structure, vertical integration and multi-divisional regional operating model.
• Max Bögl Stiftung & Co. KG: Large German Mittelstand construction and prefab concrete specialist producing concrete components, towers and turnkey buildings. Comparable in concrete prefab production (similar to KLAUS's Kissing facility) and integrated building + civil engineering delivery.
• JOH. BUNTE Bauunternehmung GmbH & Co. KG: Family-owned German construction company specializing in road construction, civil engineering and infrastructure projects. Direct overlap with KLAUS's Tiefbau / ECKLE / HOLL civil engineering businesses and asphalt paving scope.

Regional players

Highly comparable vertically integrated model, though operating primarily in western/northern Germany rather than Bavaria.
