Dewey Muller Partnerschaft mbB Architekten Stadtplaner

What Dewey Muller Partnerschaft mbB Architekten Stadtplaner does

Dewey Muller Partnerschaft mbB Architekten Stadtplaner is a privately held German partnership (Partnerschaft mbB) founded in 1988 by Burkard Dewey and Christine Muller, both previously trained in Rob Krier's office in Vienna. The firm provides integrated architecture and urban planning services from two offices in Köln (headquarters, Flandrische Straße 4) and Luxembourg (12, rue des Girondins, relocated August 2024), with a current staff of approximately 15 architects, urban planners, and designers — half its historical peak of roughly 30. Service offerings span residential architecture, urban planning and land-use plan preparation (Bauleitplanung), and advisory/competition organization, covering the full HOAI Leistungsphasen 1–9 in Germany and equivalent Luxembourg frameworks, with a distinct emphasis on citizen participation (Bürgerbeteiligung) and moderation of complex multi-stakeholder processes.

The firm's technology stack is conventional for an architectural practice: VectorWorks (CAD), V-Ray for SketchUp (rendering), ORCA AVA (tendering/procurement/billing), Adobe InDesign and Photoshop (publication), Microsoft Office, and Projekt Pro for project controlling. There is no evidence of proprietary software, automation, BIM-as-a-service offering, or AI/ML tooling. The 2016 conversion to a Partnerschaftsgesellschaft formalized a succession structure for long-term continuity.

Revenue is generated entirely through project-based professional service fees billed under German HOAI and Luxembourg local fee frameworks, with milestone-based payments tied to project phases. GTM is sales-led: the firm responds to public tenders, participates in and organizes architectural competitions, and secures repeat commissions from municipalities (Stadt Köln, Ville de Luxembourg, Ville de Differdange, Stadt Bonn, Stadt Bergisch Gladbach), public institutions (Police Grand-Ducale), religious organizations (Evangelischer Kirchenverband Köln), and private developers (Sahle Wohnen, Legend Real Estate, Fonds d'urbanisation du Plateau de Kirchberg). Marketing is reputation-driven, relying on the project portfolio website, a CleverReach newsletter (~6 issues/year), and competition wins as the primary demand-generation mechanism.
