Thomas Hillig Architects

What Thomas Hillig Architects does

Thomas Hillig Architekten GmbH BDA is a Berlin-based B2B architecture firm headquartered in Berlin-Kreuzberg, providing full-service architectural planning under the German HOAI framework across all Leistungsphasen 1–9. The firm serves four principal segments: real-estate developers and institutional investors (e.g., GSG, Nicolas Berggruen, S Immo, Berliner Volksbank); Berlin district governments and public institutions (notably Bezirksamt Reinickendorf); housing cooperatives (e.g., Baugenossenschaft IDEAL); and private clients on single-family and villa projects. Its project mix is weighted toward urban densification, heritage preservation, and the renovation/adaptive reuse of existing building stock, with a smaller but growing footprint in public-school construction following the Berliner Schulbauoffensive win.

The firm builds on a standard professional-tools stack: ArchiCAD for drafting and BIM (Building Information Modeling) for project planning and execution, supplemented by an internal sustainability practice that includes Life Cycle Assessment (LCA), Life Cycle Cost Analysis (LCC), certification support for DGNB, LEED, and BREEAM, and Ökobilanzierung using tools such as Ökobaudat and EPD programs. It has developed domain-specialized competence in Holzmodul and Holzhybrid (wood module and wood-hybrid) construction. Service lines run the full life cycle from competition/study phases through execution planning, delivered against a BDA-credentialed brand portfolio that exceeds 100 documented projects since 2000 and includes multiple 1st-place competition wins plus a 2005 Deutscher Bauherrenpreis.

The commercial model is regulated professional services: fees are calculated as a percentage of construction costs under HOAI, billed on multi-year contract cadences, and acquired through a combination of public/private competitive tenders, direct commissions, and repeat clients. The firm is privately held, founder-/partner-controlled (Thomas Hillig, Markus Friesch, Heike Reuter), with no disclosed external funding, subsidiaries, or material M&A activity; growth is internally funded and scale is anchored at approximately 30 architects operating primarily in Berlin with selected engagements in Brandenburg and other German cities.
