Eigenheim Union 1898 Beteiligungs AG is a German real estate development company specializing in the construction and sale of residential properties, including single-family houses, semi-detached houses, and terraced houses, primarily within the Berlin and Brandenburg regions. The company adopts a comprehensive and ESG-compliant approach to housing projects, bundling its construction activities under the "Eigenheim Union" segment. It owns developable land parcels managed through subsidiary project companies and offers a variety of standardized house types aimed mainly at owner-occupiers. Additionally, it operates an in-house building materials supply business to support its construction logistics. Its role in the financial market reflects its focus on providing affordable and sustainable housing solutions in a competitive metropolitan area. Despite this, the company filed for insolvency in early 2025, marking a significant moment regarding its financial and operational status.
