Belius GmbH, based in Berlin, specializes in community-driven urban planning and development. Operating from Friedrichstraße and Strelitzer Straße, the organization focuses on creating spaces that are affordable, inclusive, and sustainable. Belius takes a values-based approach to urban development, prioritizing creative, cultural, social, retail, and technological sectors. Their projects aim to foster community well-being and environmental stewardship.

Key to their strategy is the development of mixed-use spaces that accommodate diverse societal needs. For example, Belius was involved in transforming a former electric substation in Berlin's Friedrichshain-Kreuzberg district. Competing against major investment firms, they partnered with a family investment group committed to sustainable development. This project emphasizes community-centered, non-commercial real estate planning by creating spaces for entrepreneurs, social projects, and artists. The initiative also includes establishing a cooperative to finance the development through member contributions and state-subsidized loans.

Belius’s activities extend beyond traditional property development to address societal challenges such as affordability in densely populated urban areas. They integrate local engagement and long-term planning into their projects—qualities exemplified in their commitment to a 30-year development horizon for their cooperative urban initiatives.

With a clear focus on dialogue and inclusivity, Belius contributes to shaping urban environments that support cultural and social diversity, setting it apart in the competitive field of real estate and urban planning.
