Architekten BKSP

What Architekten BKSP does

Architekten BKSP is a German architecture and urban planning partnership founded in 1968 in Hannover, operating as Architekten BKSP - Obermann Ronczka Stossun und Partner mbB. The firm delivers full-scope architectural services across eight verticals: educational buildings, healthcare facilities, office and commercial buildings, residential housing, renovations and conversions, special buildings, urban planning, and competition entries. It serves both public sector clients (municipalities, state governments, universities) and private enterprises (insurance, banking, automotive), with a particularly strong portfolio in healthcare facility planning anchored by the MEDPLAN Planungsgesellschaft für Medizintechnik mbH subsidiary (est. 1993) and project management services delivered through QTB Projektsteuerung GmbH (est. 1989). All commissions in Germany are billed under the HOAI (Honorarordnung für Architekten und Ingenieure) fee regulations, the standard professional services pricing framework for German architects.

The firm's go-to-market is sales-led through architectural competitions, with over 100 documented competition wins across Germany and a 55+ year portfolio of award-winning projects including FIABCI Prix d'Excellence Gold, Deutscher Städtebaupreis, multiple BDA Prizes, and DGNB Platinum/Gold/Silver sustainability certifications. Distribution is direct to enterprise and government clients, supported by ongoing publication in architectural journals and a strong professional network. The firm has 23 employees and operates from a single Hannover headquarters, having closed a former Magdeburg branch office in 2008. Ownership is held by three managing partners (Thomas Obermann, Michael Ronczka, André Stossun) plus silent partners including Oliver Hauer and Sonja Zeyn, with no external investment or private equity involvement. Recent leadership activity includes André Stossun succeeding Jan Grabau as managing partner in December 2025 and Sonja Zeyn's admission as partner in September 2025, reflecting a controlled generational succession rather than expansionary growth.
