RIEHLE KOETH

What RIEHLE KOETH does

RIEHLE KOETH is a Stuttgart-based German architecture partnership founded by principals Hannes Riehle and Maximilian Köth, operating with a 22-person team. The firm delivers full-service architectural design across competition entry, feasibility, design development, and construction oversight for public-sector, educational, healthcare, corporate, and cultural-heritage clients. Its go-to-market is built on winning public architectural competitions, with a documented track record of first-prize outcomes on commissions for town halls, police stations, fire and emergency-services facilities, universities, research centers, and corporate headquarters across multiple German federal states.

The firm's core product is bespoke architectural design services, with a flagship project called ZERO. — a sustainable, modular, carbon-neutral timber construction prototype developed as an IBA'27 exhibit. The firm has built a distinctive reputation in timber construction (Holzbau), earning multiple sustainability and design awards for ZERO. and other projects including the Biotechnologiezentrum Tübingen and the Sparkassenhaus Reutlingen. A decade-long strategic collaboration with structural engineering firm Werner Sobek AG supports technically complex commissions.

Revenue mechanics follow the standard German architecture partnership model: project-based fees derived from competition wins, with multi-year construction-phased engagements. Pricing is not publicly disclosed. Customer mix is concentrated in the public sector and education verticals, with select corporate, healthcare, and nonprofit clients (e.g., Sparkasse Reutlingen, Universitätsklinikum Tübingen, Arolsen Archives). Geographic coverage spans Baden-Württemberg, Hamburg, Sachsen, Nordrhein-Westfalen, Hessen, Saarland, and Heilbronn, demonstrating cross-state reach from a single Stuttgart office.
