WOLFF & MÜLLER

What WOLFF & MÜLLER does

WOLFF & MÜLLER is a privately held, family-owned German construction company headquartered in Stuttgart, founded in 1936 and now in its third generation of family ownership. The company operates across multiple construction disciplines through dedicated operating subsidiaries covering high-rise and industrial construction (Hoch- und Industriebau), civil and road construction (Tief- und Straßenbau), structural engineering (Ingenieurbau), special foundation engineering (Spezialtiefbau), government services, steel and glass construction, and building renovation. As of 2025, the group reported annual performance (Jahresleistung) of €1.092 billion with 2,250 employees distributed across 24 German locations.

The company's core technology proposition centers on Building Information Modeling (BIM), in which it positions itself as a multiple-time award-winning pioneer in the German market for planning, realization, and management of buildings. WOLFF & MÜLLER also operates the Baupartnerportal, an online collaboration tool for construction partners, and offers serial/modular construction (Serielles Bauen) as a standardized building method. The group supplies its own building materials — including gravel/sand, quartz sand, asphalt, and vermiculite — through a vertically integrated subsidiary, WOLFF & MÜLLER Quarzsande. Adjacent services span purchasing optimization, energy consulting, real estate services, personnel development, insurance consulting, and project development, the latter delivered in partnership with the in-group entity DQuadrat Real Estate.

Commercially, WOLFF & MÜLLER pursues a project-based enterprise sales motion, bidding on public tenders (Ausschreibungen) and acquiring private commercial projects directly. Its customer base is split between the German public sector (federal, state, and municipal infrastructure clients including Deutsche Bahn, the City of Heilbronn, and the Erzdiözese Freiburg) and private commercial clients in industrial, commercial, and specialized research facility segments. The legal structure is a GmbH & Co. KG holding with wholly-owned operating subsidiaries, and ownership remains entirely within the founding family — no private equity, venture capital, or other external institutional investors are evidenced.

Broad incumbents

• Hochtief AG: Germany's largest general contractor and a subsidiary of ACS Group, active across nonresidential building, civil engineering and infrastructure PPPs.

Direct peers

Comparable service mix to W&M and competes for cross-border infrastructure and real-estate projects in southern Germany.
