Lengfeld & Wilisch Architekten BDA

What Lengfeld & Wilisch Architekten BDA does

Lengfeld & Wilisch Architekten BDA is a Darmstadt, Germany-based architecture firm founded in 1987 and operating as a professional partnership (PartG mbB) with 15 employees. The firm specializes in fire station design with a portfolio of 30+ completed projects across multiple German states, alongside broader competencies in office and administrative buildings, parking and transportation structures, educational facilities, urban planning, residential buildings, interior architecture, and adaptive reuse/conversion projects. Notable enterprise and institutional clients include DEVK, CMS Hasche Sigle, Nassauische Sparkasse, Merck KGaA, Software AG, T-Systems, TU Darmstadt, and Hochschule Darmstadt, with municipal public-sector work (fire stations, rescue centers) forming a significant portion of the project base.

The firm delivers full architectural services from competition entry and concept design through construction supervision, with a documented emphasis on sustainable and energy-efficient design, including photovoltaic facades, passive house standards, GreenBuilding certification (notably the Büdingen fire station recognized by the European Commission), and integration of renewable energy systems. The technology stack is conventional professional services architecture — CAD/BIM-based design workflows, energy consulting partnerships (e.g., Transsolar Energietechnik), structural engineering collaborations (e.g., B + G Ingenieure Bollinger und Grohmann, Krebs + Kiefer), and compliance with German HOAI fee regulations. There is no evidence of proprietary software, AI/ML tooling, or platform technology products.

The business model is project-based professional services, with fees structured according to the German HOAI (Honorarordnung für Architekten und Ingenieure) framework. Revenue is generated through winning architectural competitions, direct commissions from repeat enterprise clients, and participation in public-sector tenders. Marketing and sales rely on competition performance, industry awards (BDA recognition, Deutscher Betonbaupreis shortlist, Joseph-Maria-Olbrich-Plakette), and referral networks rather than outbound sales channels. Geographic reach is concentrated in Germany, with strong activity in Hesse and growing project presence in Baden-Württemberg, North Rhine-Westphalia, Rhineland-Palatinate, and Hamburg.
