What O&O Architecture does
O&O Architecture, doing business as O&O Baukunst, is a Berlin- and Vienna-based full-service architecture and urban planning firm tracing its lineage to the 1967-founded Haus-Rucker-Co avant-garde collective and operating under its current name since 1992. The firm delivers design and general planning services across seven typologies — office/corporate, cultural, retail, hospitality, residential, and urban masterplanning — with notable specializations in heritage-sensitive adaptive reuse, sustainable and climate-responsive district design, and cultural institutions. Its portfolio includes the MuseumsQuartier Wien (one of Europe's largest cultural districts, competition win 1990, opened 2001), the 160,000 sqm Wüstenrot campus, Daimler Truck campuses, and the DGB national headquarters in Berlin.
The firm is privately held as a partnership, with no external institutional investment, and operates as Ortner & Ortner Baukunst Gesellschaft von Architekten mbH in Germany and Ziviltechnikergesellschaft mbH in Austria. It is jointly managed by five partners — founders Laurids Ortner and Manfred Ortner alongside Roland Duda, Florian Matzker, and Markus Penell — supported by an office of 101–250 employees. Revenue is generated almost entirely through professional services fees on a project basis, typically structured as a percentage of construction cost or fixed design fees, with commissions secured via architectural competitions (public tenders), direct enterprise commissions, and repeat client relationships. Ancillary revenue streams include the O&O Depot art gallery, the Depotgespräche lecture series, annual publications, and the Haus-Rucker-Co historical archive.
Customers span three primary verticals — public sector/government (cities of Vienna, Bonn, Dresden; DGB), corporate and real estate developers (Daimler, Wüstenrot), and cultural/educational institutions (MuseumsQuartier Wien, Schaubühne Berlin, Ernst Busch Academy) — with the firm acting as single-source general planner on large-scale commissions. Distribution is exclusively direct and relationship-driven, with no third-party channel structure; marketing relies on architectural publications, the O&O Depot exhibition program, social media, and competition wins to build visibility.
