de Winder Architekten

What de Winder Architekten does

de Winder Architekten GmbH is a Berlin-based architecture and interior design firm founded in 1999 by Klaus de Winder and Claudia de Winder. The firm operates from a single headquarters at Schlesische Straße 26 in Berlin-Kreuzberg and is structured as a privately held German GmbH with no external investors. It employs approximately 20 staff, including architects, interior architects, and communications/marketing personnel, and is managed by its two co-founders with Sascha Nikolauschke holding Prokura.

The firm's offering is anchored in a proprietary design philosophy called "Relational Architecture" (Relationale Architektur), which positions buildings and interiors as living relationship systems rather than purely functional structures. Services are delivered across three formalised phases — Workshop & Konzept, Entwurf & Planung, and Realisierung & Evaluieren — corresponding to the full Leistungsphasen 1-8 lifecycle from site analysis and co-creation workshops through construction supervision and post-occupancy evaluation. Project work spans office and workplace design, logistics and commercial real estate, residential architecture, and heritage/campus conversions, with project footprints ranging from ~260 m² (Juris co-working) to ~31,000 m² (an unnamed international consultancy HQ across 21 floors).

Commercially, de Winder runs a sales-led, professional services model with project-based pricing and no publicly disclosed fees. Enterprise clients include Vattenfall, Zalando, Carlsen Verlag, Mozilla, neXenio, Topas, Wall, SSF Ingenieure, and Hörbuch Hamburg. Demand generation is driven primarily by an extensive project portfolio on its website, a curated award strategy (German Design Award, ICONIC Awards, Dezeen, DGNB Diamant), and repeat-client referrals, with founders directly engaged on major engagements throughout the project lifecycle.
