What Haas Cook Zemmrich does
haascookzemmrich STUDIO2050 is a privately-held German architectural partnership (Freie Architekten PartG mbB) founded in April 2012 by Martin Haas, David Cook, and Stephan Zemmrich — all previously senior practitioners at Behnisch Architekten. The firm operates from Stuttgart (headquarters, relocating to Forststraße 9 in December 2025), with additional offices in Landau (opened 2025 under partner Sandro Ruiu) and Shanghai (operating since 2017 under Hanxiao Liu), and currently employs approximately 40+ architects, associates, and support staff. It generates revenue through professional-services fees for architectural commissions governed by the German HOAI fee structure, acquiring the majority of its work through participation in architectural competitions (Wettbewerbe) and invited tenders, with additional pipeline from repeat clients and event-driven reputation building via industry lectures and publications.
The firm's technical signature is a design philosophy the founders call 'Low Tech – High Nature': a deliberate preference for simple, low-technology construction methods paired with high natural material quality. Core competence areas include natural-material construction using rammed earth (Stampflehm), timber (Holzbau), and clay; circular construction with documented component reuse (Town Hall Schömberg, Leibniz Innovation Centre, Königstraße 1ab); and climate-adaptive passive design. Projects are planned using BIM-based workflows and delivered across all German HOAI Leistungsphasen (1-9), from competition entry through site supervision. The practice is institutionally embedded in German sustainability infrastructure — Martin Haas is a co-founder and Vice President of the DGNB — and its portfolio includes DGNB Platinum-certified buildings (Alnatura Campus) and multiple international award-winning flagship projects (Rapunzel Welt, enercity HQ).
The firm's client base spans corporate and commercial (Rapunzel Naturkost, enercity, Alnatura, Promega, Mercedes-Benz, Hypoport), culture and public (Experimenta Heilbronn, Concert Hall Ventspils, Frankfurt Conservation Center), residential and housing (VielArten Tübingen Baugruppen), urban planning and mobility (Groter Pohl Rostock, Smart Mobility Hub Stuttgart, mobility hubs in Bremerhaven and Stuttgart), and select education and healthcare projects. Distribution occurs exclusively through direct client engagement via competitions and tenders; there are no digital or retail channels. Marketing and brand-building are executed through competition wins, partner lectures at industry conferences (BAU München, Holzbauforum, DGNB events, Architect@Work), earned media in architecture publications (Detail, Baunetz, ArchDaily, Frame), exhibitions, and Instagram — yielding a CompetitionLine ranking of 16th nationally and 30+ documented industry awards across the past decade.
