What Wenzel + Wenzel does

Wenzel + Wenzel is a privately held German architecture and engineering consultancy founded in 1958 and headquartered in Karlsruhe, operating 15 offices across Germany plus Wrocław (Poland) and Vienna (Austria) through wholly-owned subsidiaries and integrated adjacent firms (Hahn Helten Architektur, Ingenieurbüro Schmid GmbH). With a workforce of more than 400 drawn from 35 nationalities, the firm delivers full-service architectural execution across all nine HOAI service phases (Leistungsphasen 1–9), from cost and schedule planning through execution planning, tendering, construction supervision, and post-construction object management. Its core proposition is translating the designs of internationally renowned architects (David Chipperfield, JSWD, Staab Architekten, allmannwappner, Dietrich Untertrifaller, TRU Architekten) into built reality on technically complex projects.

The firm's project portfolio spans education, healthcare, cultural institutions, transportation infrastructure, administration, residential, sports, and special-purpose buildings, with marquee commissions including Terminal 3 at Frankfurt Airport (2012–2023), the Porsche Museum, Mercedes-Benz Museum, Museum of Modern Literature Marbach, the Stadtbahntunnel Karlsruhe, and the upcoming Junge Bühne Dortmund and Gutenberg-Museum Mainz. Revenue is earned as professional service fees negotiated on a project basis and structured against HOAI milestones, with new work acquired through competitive tendering, architectural competitions, and direct commissions from public administrations and private developers. The firm is a member of BIM Allianz e.V., DGNB, and Madaster, and has built specialized practices in circular construction (with Concular) and inclusive design (Inklusive Baukultur), positioning it within the German construction sector's digital and ESG transformation agendas.
