hdg Architekten

What hdg Architekten does

hdg Architekten is a privately held German architectural partnership headquartered in Bad Kreuznach, operating as hdg Architekten BDA - Henninger und Lachenmann Partnerschaft mbB since the 2016 generational succession from founder Heinz-Dieter Gerharz to managing directors Fabrice Henninger and Florian Lachenmann. The firm provides full-scope architectural services under the German HOAI fee structure (LP 1–9), spanning project management, client consulting, construction supervision, feasibility studies, and expert opinions, with BIM-based planning on VectorWorks CAD/BIM workstations and an in-house 3D printing model workshop. Service verticals include residential (multi-family, social housing, intergenerational living), commercial and office, industrial/manufacturing, healthcare (notably the Ospedale Maggiore Policlinico Milan collaboration with HPP Architekten), education, and urban planning, with sustainability certification advisory across DGNB, LEED, and BNB standards.

Revenue mechanics are project-based fees regulated by HOAI, with project acquisition driven by direct enterprise engagement, public tenders, architectural competitions (a core go-to-market channel yielding multiple 1st and 2nd prizes), and referrals through BDA and Architektenkammer networks. The firm has completed over 50 documented projects spanning 1977 to 2026 across Germany (Baden-Württemberg, Rhineland-Palatinate, Bavaria, Hesse, Lower Saxony) and select international locations in the Netherlands, Italy, Spain, Bulgaria, and Chile. The team consists of approximately 11 professionals — two managing directors, three architects, three construction/technical draftsmen, one senior architect advisor, and two interns — supplemented by a specialized interior design sub-brand, raumspielkunst, operated by the same managing partners. Revenue is not publicly disclosed; based on headcount and HOAI fee benchmarks, the firm is estimated to operate in the low single-digit million Euro range annually.

The firm differentiates via dual identity combining the BDA-credentialed professional architectural practice with the artistically positioned raumspielkunst interior label, sustained brand recognition from a continuous award record (German Design Award, Iconic Awards, Callwey Häuser des Jahres, Architektenkammer Baden-Württemberg recognition), and deep collaborative partnerships with HPP Architekten and bauchplan that enable participation in projects beyond its solo capacity. Marketing is executed through portfolio website, professional publications (Bauwelt, AIT, Archdaily, Cube Magazin), competition participation, exhibitions including the Architecture Biennale of Venice, and organic social channels.
