Lindner Lohse Architects BDA

What Lindner Lohse Architects BDA does

Lindner Lohse Architekten BDA PartG mbB is a Dortmund-based architecture firm founded in 1998 by Harald Lindner and Frank Lohse, restructured in February 2020 into a partnership of five BDA-credentialed architects (Lindner, Lohse, Wibke Evert, Uwe Becker, David Auerbach). The firm delivers professional architectural services across four core capabilities — new construction (Neubau), renovation (Sanierung), extension (Erweiterung), and conversion (Umbau) — applied to five building typologies: education, cultural heritage, residential, office/administration, and special-needs facilities.

Its portfolio is anchored in North Rhine-Westphalia and the Ruhr area, with flagship projects including the Welterbe Forum Zollverein visitor center on the UNESCO World Heritage site, the German Mining Museum Bochum winding-tower restoration (jointly with Vervoorts & Schindler Architekten BDA), and a series of school modernizations and extensions for municipal clients. The firm holds DIN EN ISO 9001:2015 certification, is a member of the Bund Deutscher Architekten (BDA) since 2001, and operates under the Architektenkammer NRW regulatory framework.

The business model is project-based professional services: fees are calculated under the German Architecture Fee Ordinance (HOAI) as a percentage of construction costs or as time-based charges, billed across multi-year contracts. Go-to-market is enterprise field sales driven by architectural competitions, public procurement tenders, and direct referrals. The customer base is concentrated in the public sector (federal, state, and municipal agencies) and non-profit institutions, with a minor private-residential segment. The firm has 11-50 employees and operates from a single headquarters in Dortmund.
