Lehnert

What Lehnert does

Lehnert GmbH is a German specialty construction subcontractor founded in 1977 (or 1980 per alternate sources) and headquartered in Fernwald (registered in Gießen), Hesse, that designs, manufactures, and installs modular system partition walls for office, industrial, and acoustic applications. The company is now in its third generation of family ownership, with Robert Köppen joining his father Lutz Köppen as Managing Director on January 1, 2024. The product portfolio is organized into three lines: Bürowelten (office walls including Lehnertwand Modula, Forma, Vista, Vista DUO, FireProtect, and the mobile 2040 system), Industriewelten (industrial partition walls up to 10 meters height and the Lehnertkabine room-in-room cabin), and the KONOA Akustikwelten acoustic solutions sub-brand launched in 2024. Core technology centers on proprietary modular wall systems combining glass, aluminum, steel, and wood components, with certified technical performance including sound insulation up to 51 dB (Vista DUO), 30-minute fire resistance (FireProtect), and reversibility supporting circular-economy reuse.

The company's underlying technical platform includes proprietary frameless glass construction (Ganzglasbauweise), stud construction systems (Ständerbauweise), and specialized radiation protection builds, all manufactured in-house at the Fernwald facility with CNC machinery, painting lines, and a KfW-40 standard production hall inaugurated in 2023 with 99 kW solar capacity. Lehnert operates a vertically integrated business model as a Generalübernehmer (general contractor), providing end-to-end project execution from on-site situation analysis and CAD planning through manufacturing to installation. Revenue is generated exclusively through custom project-based one-time contracts with no public pricing; quotes vary by dimensions, materials, fire/acoustic specifications, and installation complexity.

The go-to-market combines a PLZ-based regional sales representative network across Germany with exclusive channel partners Wagner Objekt GmbH in Austria and Hallenbüro GmbH in Switzerland/Liechtenstein, targeting enterprise B2B customers in commercial real estate, industrial manufacturing, and specialized verticals (notably a €5M+ Siemens Healthineers radiation protection cabin contract in Forchheim/Bayern). Marketing efforts center on the company website (lehnert-gmbh.de), LinkedIn and Instagram presence, and trade fair participation (ORGATEC 2024 in Cologne), supplemented by educational content on workplace regulations and design trends. FY2022/2023 revenue stood at €24.5 million with 40% YoY growth, and headcount reached approximately 100 employees including apprentices.
