About DÜMA Hoch- und Mitbau
DÜMA Hoch- und Mitbau GmbH, based in Dülmen, was founded in 1987 by Dipl.-Ing. Architect Heinrich Etterich. The company operates as a developer and general contractor, realizing mass houses, single- and two-family houses, and semi-detached houses in the development areas of the northern Ruhr region and the southern Münsterland. The core offering is the trademark-protected DÜMA Participatory Construction System®, where clients carry out trades entirely or partially themselves, guided by a company specialist. In addition to turnkey projects, the service portfolio includes individual planning, financing consultation, masonry, concrete, and reinforced concrete work, as well as the acquisition, sale, and brokerage of real estate. With approximately 16 employees and an annual revenue of about 4.5 million €, the company is one of the established developers in the Coesfeld district. In December 2025, insolvency proceedings were opened; the company is in liquidation.
