Hidden Architects

What Hidden Architects does

Hidden Architects, operating as HTP Hidde Architekten GmbH, is a German private-limited architecture firm founded in 1970 in Braunschweig and specializing in innovative scientific and research-building architecture. The firm designs highly complex technical facilities — including laboratory buildings, clean rooms (up to ISO Class 3 / class 1000), vibration-sensitive research halls for electron microscopes, wind tunnels, satellite control operations centers, quantum technology competence centers, and marine research institutes — primarily for German public-sector clients such as universities (TU Braunschweig, Universität Hamburg, Universität Bonn, WWU Münster, Carl von Ossietzky Universität Oldenburg), federal research bodies (DLR, Fraunhofer, Helmholtz, PTB, DFKI), and government-backed technology-transfer centers.

The firm operates as a full-service practice across HOAI Leistungsphasen 1-9, providing architectural design, general planning (Generalplanung), and in-house laboratory-technology planning. It does not produce software, AI models, or standardized products; every output is a custom building project delivered by a specialized multi-disciplinary team. Under Managing Director Lars Hidde, who has led the firm since 2001, the company runs a 11-50 employee practice from its Braunschweig headquarters and a second office in Hamburg-Blankenese opened in 2020.

Revenue is generated through professional-service fees on individual building projects, calculated per the German HOAI fee schedule and acquired through architectural competitions, VgV/VOF public-tender procedures, and direct client relationships with research institutions. Marketing is portfolio-driven (project website, Instagram, LinkedIn, Facebook, BDA recognition). The firm holds no external funding, has no parent company, and operates as a founder-owned GmbH with steady, competition-led growth tied to German public R&D investment cycles.
