Sternbau GmbH

What Sternbau GmbH does

Sternbau GmbH is a privately held German construction company (GmbH) founded on January 30, 1995, and headquartered at Byhlener Straße 1, 03044 Cottbus, in the Brandenburg/Lusatia region. The company delivers a full spectrum of building services spanning turnkey construction (Schlüsselfertiges Bauen), rough structural work (Rohbauarbeiten), demolition including vibration- and dust-reduced techniques using diamond concrete drilling and sawing, building renovation and complex restoration (Bausanierung), special civil engineering (Spezialtiefbauarbeiten), and end-to-end construction preparation, planning, supervision, and coordination. A distinctive capability is the integration of regional small and medium-sized craft enterprises into project execution, supported by an in-house apprenticeship program established in 1998 across masonry, carpentry, and administration trades.

The company serves institutional and public-sector clients across multiple verticals in the regional market, including municipal government (Stadtverwaltung Cottbus, Gebäudewirtschaft Cottbus GmbH, Stadtwerke Cottbus GmbH), healthcare (Carl-Thiem-Klinikum Cottbus, Medicus Cottbus, LAFIM), research institutes (DLR, Fraunhofer), sports organizations (FC Energie Cottbus), and regional property developers. Notable delivered projects include the 120-unit Wohnpark Cottbuser Heide residential development, the Seniorenresidenz Mühleninsel, the Bürohaus am Campus for DLR and Fraunhofer (81 offices, 6 conference rooms), and the recently completed Rettungswache at Universitätsklinikum Cottbus. The reference portfolio exceeds 90 documented projects over the 30-year operating history.

Sternbau generates revenue through project-based one-time contracts with enterprise and government clients, with pricing determined per-project scope. Go-to-market relies on direct enterprise field sales and formal public-sector tendering, supplemented by a website project portfolio and word-of-mouth referrals rather than active digital marketing. The company is independently owned, with Jörg Schnapke serving as Managing Director (Geschäftsführer), and operates exclusively within the Cottbus/Brandenburg region with no documented geographic expansion plans.
