What Primus Developments does
PRIMUS developments GmbH is a Hamburg-headquartered project developer founded in 1999 by Achim Nagel, specializing in sustainable timber and timber-hybrid modular construction. The company develops, plans, and constructs residential, commercial, and public buildings across Germany, with regional offices in Berlin and Düsseldorf and a realized cumulative project volume of approximately €1.2 billion across more than 15 completed projects. Its core technology is industrial prefabrication of solid wood (Massivholz) modules combined with cast-in-situ concrete ground floors and stairwells, achieving 80-85% off-site fit-out completion in dedicated manufacturing facilities operated by its strategic partner Kaufmann Bausysteme. Signature projects include the WOODIE student housing complex in Hamburg (371 units, the world's largest timber module building at completion in 2016), LUISE in Berlin's government quarter for the German Bundestag (460 modules, 17,000 m² BGF, delivered in 18 months), and the Zollhochschule Rostock (Europe's largest timber module construction project at ~55,000 m² with 1,000+ modules, handed over 2026).
The company's revenue model rests on three streams: project development and construction services for public-sector clients secured through competitive tendering (BBR, BImA, Bundestag, Bundespräsidialamt); privately financed residential and commercial development sold to individual buyers, housing associations, and investors; and a hybrid model (e.g., WILLIE under Hamburg-Standard) combining public land allocation with private financing for affordable housing. Differentiation is anchored in the proprietary WOODCYCLE reforestation concept (committing to regrow all timber used), digital resource passports (Materialpässe) via the Madaster platform enabling buildings as material banks, deep sustainability credentials (DGNB Gold, HafenCity Gold), and recurring collaborations with premier architectural firms (Sauerbruch Hutton, gmp, Eike Becker Architekten). The firm is family-owned and led by Managing Directors Achim Nagel and Lorenz Nagel, with a wholly-owned operating subsidiary (Prime Site Development).

Revenue model
- Real Estate Project Development and Construction: PRIMUS developments generates revenue by developing, planning, and constructing residential, commercial, and public buildings. The company acts as project developer (Projektentwickler) and general contractor (Totalübernehmer in partnership with Kaufmann Bausysteme). Revenue is realized through the sale or lease of completed buildings to end-users, investors, or government clients. Projects range from student housing (WOODIE, 371 units) and federal office buildings (LUISE for the Bundestag, ~17,000 m² BGF) to office ensembles (ROCKYWOOD, ~10,000 m² office space) and hotel/residential developments. The company has realized a project volume of approximately €1.2 billion.
- Public Sector Construction Contracts: PRIMUS secures direct contracts from public-sector clients (Bundesbehörden, federal agencies, municipal governments) through competitive tendering. Projects such as the Bundesamt für Bauwesen und Raumordnung office building for the German Bundestag (LUISE), the Federal Customs School (Zollhochschule) in Rostock, and the Bundespräsidialamt temporary facility in Berlin are awarded via public procurement. Revenue is recognized upon project completion and handover.
- Privately Financed Residential and Commercial Development: The company develops privately financed projects (e.g., WILLIE affordable housing, Marina Gardens, Neues Wallufer Lübeck) that are sold to individual buyers, housing associations, or investors upon completion. These follow a traditional property development revenue model where revenue is generated at point of sale or through rental income.
