UNIT4 GmbH & Co. KG - part of DREES & SOMMER

What UNIT4 GmbH & Co. KG - part of DREES & SOMMER does

UNIT4 GmbH & Co. KG is a Stuttgart-based architecture and engineering firm operating as an EPCM (Engineering, Procurement, Construction Management) provider for complex construction projects. Founded in 2005 by Peter Menius and Stefan Baier, the firm is a wholly-owned subsidiary of Drees & Sommer SE, with three Managing Directors (Baier, Menius, and Stephan Thulmann, who joined in 2023 from Drees & Sommer). UNIT4 has 27 employees and operates from Stuttgart headquarters, with a newly opened regional office in Dresden as of July 1, 2025.

The firm delivers four integrated service lines: Project Consulting, Architecture, General Planning, and Project Management, structured under HOAI fee regulations (the German architects' and engineers' fee ordinance). Core technology centers on BIM (Building Information Modeling) for interdisciplinary coordination across architecture, structural design, infrastructure, and MEP systems, supplemented by specialized vibration measurement and baudynamic analysis for nanoscale-sensitive facilities. The differentiated offering is the design of vibration-controlled and clean-room environments for semiconductor, microelectronics, pharmaceutical, and biotechnology manufacturing — capabilities evidenced by client work for Infineon, Bosch, GlobalFoundries, Boehringer Ingelheim, Novartis, Lonza, and AMD.

Revenue is project-based, primarily through direct enterprise engagements and public tenders, with fees structured under HOAI or negotiated project contracts. UNIT4 pursues its work through direct client relationships in the DACH region and has executed projects in Austria, the Czech Republic, Sweden, and Hungary. As a boutique firm within the larger Drees & Sommer SE ecosystem, UNIT4 operates as a focused P&L unit with reputational positioning in advanced technology and life sciences facility design, rather than as a high-volume generalist practice.

Broad incumbents

• Drees & Sommer SE: UNIT4's parent company and one of Europe's largest construction and real estate consulting firms, with broad capabilities across project management, engineering, and infrastructure. Comparable because Drees & Sommer's project controls and EPCM services overlap directly with UNIT4's General Planning and Projektsteuerung offerings.
• Arup: Global engineering and design consultancy with deep expertise in vibration, acoustics, and complex technical buildings. Comparable because Arup competes in the same high-tech industrial and life sciences architecture space as UNIT4, and brings specialized building physics capabilities that mirror UNIT4's vibration damping differentiator.
• WSP: Global professional services firm with a sizable European property and buildings practice serving industrial and life sciences clients. Comparable because WSP competes with UNIT4 in BIM-enabled architecture and project management for high-tech and pharmaceutical facility projects, especially in the DACH region.
• HDR Inc. Global architecture and engineering firm with a strong high-tech, healthcare, and industrial facility practice. Comparable because HDR pursues many of the same semiconductor, pharma, and biotech manufacturing facility clients as UNIT4, and offers integrated architecture, BIM, and EPCM services at much greater scale.
• Arcadis: Global design, engineering, and consulting firm with strong European presence in industrial and life sciences facility design. Comparable because Arcadis competes for many of the same European semiconductor, pharma, and biotech facility projects as UNIT4, with broader geographic reach and integrated consulting capabilities.
• Jacobs Solutions: Large global professional services firm with a critical mission solutions and advanced facilities business serving semiconductor and life sciences clients. Comparable because Jacobs pursues the same high-tech EPCM and architecture opportunities as UNIT4 with much greater geographic and resource scale.

Direct peers

• SSOE Group: US-based architecture and engineering firm with significant high-tech industrial, semiconductor, and battery facility expertise. Comparable because SSOE directly competes in semiconductor and advanced manufacturing facility design with BIM-driven delivery, mirroring UNIT4's high-tech industrial focus.
• Exyte (formerly M+W Group): Global specialist in high-tech facility design and construction for semiconductor, pharmaceutical, and biotech clients. Comparable because Exyte directly competes for clean-room and vibration-sensitive facility projects with UNIT4's core customer base, though at significantly greater scale and global footprint.
• HPP Architekten: German architecture firm specializing in complex, large-scale buildings including high-tech industrial, healthcare, and corporate headquarters. Comparable because HPP operates with a similar German regional base, serves enterprise clients on technically demanding projects, and competes in many of the same tenders as UNIT4.
