Lindner Architects

What Lindner Architects does

Lindner Architekten GmbH & Co. KG is a privately held architectural practice headquartered in Düsseldorf, Germany, founded in 1959 by Otto Lindner. Following the founder's death on January 1, 2020, the firm was converted to a GmbH & Co. KG structure and is now led by two managing partners — Sabrina Muth-Kieslich (appointed February 2023) and Daniel Schwecke (appointed 2018). The firm employs approximately 35 architects, interior designers, engineers, and administrative staff and operates from a single office at Emanuel-Leutze-Straße 17, Düsseldorf-Lörick. Its service portfolio spans four core disciplines — Architecture, Interior Architecture, Building in Existing Stock (Bauen im Bestand), and Heritage Conservation (Denkmalpflege) — delivered across the full HOAI Leistungsphasen 1-9, from concept and design through construction management. Planning is conducted using BIM-based methodology, with stated "responsible" experimentation with AI tools in design processes.

The firm serves a diversified client base across commercial real estate developers, corporate and institutional clients, hospitality operators, public-sector bodies, and senior-living operators. Named clients include D.Live, diedeveloper, Messe Düsseldorf, ERGO, IHK Düsseldorf, Lindner Congress Hotel, Seniorenresidenz Haus Schlosspark, SD Schulbaugesellschaft Duisburg, and IDR, with multiple repeat engagements. Project work is concentrated in Germany (Düsseldorf, Krefeld, Duisburg, Frankfurt, Leipzig, and 15+ other cities) with selective international commissions in Russia (Nebug Resort) and Switzerland (Crans-Montana). The firm has won two German Design Awards in 2025 (Architecture for OPUS Krefeld; Interior Architecture for CAVE 01 & 02) and the Coolster Tagungsraum 2018 first prize.

Revenue is generated through project-based professional services engagements, with fees structured according to the German HOAI fee scale (percentage of construction cost or hourly billing) on multi-year contracts. Go-to-market is sales-led: direct client engagement, project tenders, and trade-fair presence at EXPO REAL (Munich), polis Convention (Düsseldorf), and the WIA Festival. Distribution is purely direct — no resellers, marketplaces, or channel partners. Revenue figures are not publicly disclosed; with ~35 staff and a single headquarters, the firm is best characterized as a mid-sized, full-service regional architecture practice with selective national reach.
