LRO

What LRO does

LRO GmbH & Co. KG is a Stuttgart-based architecture firm founded in 1979, with approximately 50 employees and a second office in Berlin operating as Lederer Ragnarsdóttir. The firm specializes in public buildings, cultural facilities, educational institutions, and religious structures, serving primarily public-sector clients — municipalities, dioceses, and state entities — alongside a smaller portfolio of corporate clients. The firm's portfolio includes museums, schools, libraries, churches, theaters, and administrative buildings, with notable commissions such as the Deutsches Museum Zentraldepot in Munich, Bertha-Benz-Schule in Stuttgart, and the Münchner Volkstheater (a Mies van der Rohe Award 2025 nominee).

Service offerings span urban planning, building construction, and sustainable design, with project scopes ranging from feasibility studies through construction supervision. The firm increasingly participates in the ÖPP (Öffentlich-Private-Partnerschaft / public-private partnership) delivery model in partnership with Georg Reisch GmbH, which positions it for large, integrated public commissions where solo architecture practices are typically excluded.

Revenue mechanics are governed by the German HOAI (Honorarordnung für Architekten und Ingenieure) fee regulations, with project fees scaled to project cost and complexity. The customer base splits between public-sector contracts (dominant, procured under VgV and UVgO frameworks) and selective corporate engagements with dm-drogerie, Sparkasse, Würth Elektronik, and SWR. The 2023 generational transition has stabilized leadership continuity, and the firm is currently executing a multi-year pipeline of commissions extending through 2026.
