What Kolling Architects BDA does
KÖLLING ARCHITEKTEN BDA is a family-owned German architecture firm founded in 1970 by Bernd Kölling in Bad Vilbel near Frankfurt am Main, now operating as KÖLLING ARCHITEKTEN PartG mbB under the second-generation partnership of Bernd, Moritz, and Sabine Kölling. The 70-employee practice delivers full-scope architectural services across all HOAI service phases (Leistungsphasen 1–9), organized into seven offerings: architectural design, urban planning, economic planning, interior and color design, quality and sustainability, 3D model building and visualization, and continuation construction (renovation/adaptive reuse of existing buildings including heritage-listed structures). The firm also actively competes in architectural competitions (Wettbewerbe) under regulated German procurement frameworks (VgV, RPW, SektVO).
The practice primarily serves German public-sector clients — municipalities, state governments, public utilities, and cultural institutions — winning projects through architectural competitions and direct commissions. Notable clients include Stadt Frankfurt am Main, Stadt Nürnberg, Messe Frankfurt Venue GmbH, VGF (Frankfurt transit), Mainova AG (energy utility), KMW Mainz-Wiesbaden, and religious/nonprofit institutions such as the Evangelische Kirchengemeinde Lörrach. Project types span fire stations, schools, libraries, exhibition halls, museums, transit stations, churches, residential master plans, and increasingly energy and data-center infrastructure.
Revenue is generated almost exclusively through professional-services fees regulated by the German HOAI fee schedule (Honorarordnung für Architekten und Ingenieure), with project-based, multi-year contracts. The firm has developed a proprietary typified fire-station modular building system (Gebäudesystem Feuerwehr) won through a 2018 VgV competition, now being deployed across six Nuremberg districts. The firm's go-to-market is essentially enterprise field sales via public tenders, supplemented by professional-network visibility through BDA (Bund Deutscher Architekten) membership and competition prize announcements.
