Riegler Riewe Architects

What Riegler Riewe Architects does

Riegler Riewe Architekten is a privately held architecture and general planning firm (Ziviltechnikerbüro) founded in 1987 in Graz, Austria, by Arch. DI Roger Riewe. The firm operates from three offices — Graz (headquarters), Vienna, and Berlin (via the wholly-owned German subsidiary Riegler Riewe Architekten GmbH) — and is managed by three Geschäftsführende Gesellschafter: Roger Riewe, Christian Story, and Michael Münzer. Headcount is reported in the 11–50 range.

The firm delivers full-service architectural design, project management, and execution supervision across five primary practice areas: cultural and educational buildings, healthcare and research facilities, infrastructure, urban development and housing, and sustainability-focused projects. Its core methodology centers on participation in architectural competitions — the dominant procurement mechanism for public and institutional commissions in Austria and Germany — supplemented by direct commissions from recurring institutional clients such as BIG (Bundesimmobiliengesellschaft), the Medical University of Graz, and various municipal governments. The firm has executed projects across approximately 15 countries, with signature works including the MED UNI CAMPUS Graz (53,449 m², ÖGNI/DGNB Platinum), the Schlesisches Museum Katowice (underground museum on a former coal mine), the König Galerie Berlin (St. Agnes conversion, Mies van der Rohe Award 2017 nominee), Hauptbahnhof Innsbruck, and the Holtenau Ost 90-hectare urban quarter in Kiel.

Commercially, the firm operates on a professional-services model with project-specific, quote-based fees that are not publicly disclosed. Marketing is primarily reputation-driven: awards (Austrian State Prize 2023, multiple Mies van der Rohe nominations, ÖGNI/DGNB Platinum, BIG SEE Award 2019), competition wins, conference lectures, and exhibitions rather than paid acquisition channels. The firm maintains no AI/ML capabilities or proprietary technology platform, competing instead on design quality, competition track record, partner credentials, and relationships with public-sector clients. There is no external investment or private equity involvement; the firm is partner-controlled and remains independently owned.
