What hochschule kaiserslautern, universi does

Architekturbüro de Fries is a sole-proprietor architecture practice founded in 1995 by Sabine de Fries, Dipl.-Ing. Architektin BDA, and headquartered at Lämmchesbergstraße 7, Kaiserslautern, Germany. The firm delivers full architectural services across all nine HOAI Leistungsphasen, from preliminary design and design development through construction documents, tendering, and on-site supervision. Its project portfolio spans residential (single-family, multi-family, lofts, penthouses, senior living), commercial and industrial (production halls, warehouses), cultural and institutional buildings (museum renovation, kindergarten, church conversions), and heritage/denkmalgeschützte conservation work. The firm is a member of Architektenkammer Rheinland-Pfalz and the founder is a BDA-credentialed architect.

The firm operates a project-based professional services revenue model with fees structured per the HOAI framework governing German architectural pricing. Go-to-market is sales-led and relationship-driven, relying on portfolio visibility via de-fries.de, BDA and chamber membership referrals, and direct commissions from regional clients in the Pfalz region including Kaiserslautern, Otterberg, Weilerbach, Bad Dürkheim, Edenkoben, and Enkenbach-Alsenborn. Notable documented engagements include the Museum Pfalzgalerie Kaiserslautern renovation (€3M construction volume, 2007-2013, client Bezirksverband Pfalz), HegerGuss GmbH production hall (€7.5M, Enkenbach), and ongoing residential developments via partner Imraum GmbH.

Sabine de Fries also serves as managing director of Imraum GmbH, a separate property development entity that collaborates with the practice on integrated design-and-build residential projects such as the W22 apartments, Otterberger Hof conversion, and the Christ König church-to-residential adaptive reuse. The practice is GDPR-compliant, bound by the Architektengesetz Rheinland-Pfalz professional code, and reports no external investment, parent company, or subsidiaries. Operational scale remains modest and founder-centric, with no disclosed headcount, no funding rounds, and revenue not publicly disclosed.
