IAAG Architekten AG

What IAAG Architekten AG does

IAAG Architekten AG is a Bern-headquartered Swiss architecture firm (Aktiengesellschaft) that traces its lineage to a practice founded in 1900, operating under the current corporate identity since 2001. The firm delivers full-service architectural and general planning services across new construction, renovation, and conversion for complex institutional buildings, with particular depth in healthcare facility design (hospitals, operating theatres, research centres), senior living and care facilities, education, and public institutions, plus adjacent scenography and exhibition design. Project work is executed with Building Information Modeling and supported by ARGE (Arbeitsgemeinschaft) joint ventures with peer firms such as mrh Architektur, GWJ Architektur, and the German practice ASTOC for the largest mandates. The active portfolio includes the CHF 330 million Anna-Seiler-Haus for Inselspital Bern, the CHF 250 million Forschungs- und Ausbildungszentrum Medizin for the Universität Bern, the CHF 265 million Spitäler Schaffhausen renewal, and the recently completed Neue Festhalle Bern (opened April 2025), alongside ongoing multi-phase hospital programmes for Inselspital, Lindenhofspital, and Berner Klinik Montana.

The firm's revenue model is project-based professional services: fees are negotiated per mandate or won through Swiss architectural competitions (Wettbewerbe), with no published pricing and no standardised SaaS, subscription, or product revenue. Go-to-market combines participation in municipal, cantonal, and federal architectural competitions with direct commissions cultivated through long-tenured relationships with Swiss public-sector and institutional clients (hospitals, cantonal building authorities, the Swiss National Bank, education authorities, and exhibition operators such as Bernexpo AG). Geographic focus is Switzerland, concentrated in Canton of Bern, with selected project wins extending into Central Switzerland, Valais, Schaffhausen, and the Lake Geneva region, plus occasional cross-border scenography commissions in France (Annecy).

Governance is partner-led: Alain Kohlbrenner serves as Managing Director (Geschäftsleiter) and board member, Andreas Stebler as President of the Board, with Katharina Schwippe and Richard Bratschi as board members, and Markus Bohren heading construction management. The firm employs roughly 16 full-time staff plus apprentices (~21 listed on the team page), holds SIA and SIB sector memberships, and operates as a privately held company with no external investors, subsidiaries, or disclosed financial statements.
