What Steiger Concept AG does
Steiger Concept AG is a privately held Swiss architecture and general-planning firm (Aktiengesellschaft) headquartered in Zürich at Rüdigerstrasse 15, tracing its origins to the mid-20th-century practice Haefeli Moser Steiger. The firm operates as a Generalplaner, delivering architecture, planning, and construction-management services across SIA phases 33–52 and BKP 1–9, with a portfolio of 300+ projects spanning hospitals, public infrastructure, residential, commercial, and airport buildings across Switzerland. Its core technical method is Building Information Modeling (BIM), explicitly referenced across major hospital mandates (e.g., Kantonsspital Aarau Haus 17 executed 'alles in BIM'), and the firm self-describes as a 'digitale Architekturwerkstatt.'
The business model is professional-services-based, with fees negotiated per mandate using SIA 112 fee frameworks and billed via multi-year project contracts; revenue is entirely project-based and tied to commission lifecycles. Projects are acquired through public architectural competitions (offener/selektiver Projektwettbewerb), direct commissions, and selective tenders, with the firm maintaining long-tenured institutional relationships with cantonal hospitals (Inselspital Bern, Universitätsspital Zürich, Kantonsspital Aarau, Kantonsspital Baden, Luzerner Kantonsspital, Kantonsspital St. Gallen), airport operators (Flughafen Zürich AG), and real-estate developers. Recent wins include 1st-Rang competition outcomes for Spitalneubau Biel-Brügg (250 Mio. CHF) and Polizei- und Sicherheitszentrum Schaffhausen.
The firm has a team of approximately 30 architects and specialists led by Managing Director Thomas Keller, with executive board members Benedikt Heesen, Martin Wengle, and Sergio Bruns, and additional offices in Valencia, Spain. It operates without external capital or parent ownership under a partnership-style structure, supported by an ecosystem of co-consulting landscape architects (BNP, vetschpartner) and external creative partners (Raffinerie AG, SNØ GmbH) for communications.
