Architekturbüro Planwerk

What Architekturbüro Planwerk does

Architekturbüro Planwerk GmbH & Co.KG is a Würzburg-based German architecture practice founded in 1991 by Stefan Buttler (Dipl.-Ing., Geschäftsführer). The firm delivers the full HOAI service spectrum (Leistungsphasen 1–9), covering project development, design, permit planning, tendering, construction supervision, interior architecture, fire protection concepts, property valuations, and SiGeKo safety/health coordination. Its core competency is healthcare architecture — medical centers, day clinics, operating rooms, laboratories, and specialized clinics — where regulatory, hygiene, and discipline-specific planning requirements are central. Beyond healthcare, it serves residential developers, commercial clients (offices, logistics), hospitality (notably Hyatt Regency Mainz), retail (Königshofgallerie), and private individuals on bespoke homes and renovations.

The business model is professional services fee-for-project under the German HOAI fee structure, with revenue generated directly through client engagement rather than digital channels or third-party intermediaries. The firm operates primarily across Germany with select European projects, and is delivered by a team of approximately 5 professionals out of offices on Ottostraße and Zwinger in Würzburg. Distribution is referral- and reputation-driven, with the website functioning as a project portfolio showcase rather than a lead-generation engine. There is no venture capital, private equity, or institutional investor involvement; ownership remains with the founder, who restructured the legal entity to a GmbH & Co.KG in 2024 as a future-proofing measure.
