Wohnen im Grünen Markt is an innovative housing project located in Vienna's Sonnwendviertel, near the main train station. Completed in 2019, this mixed-use development combines residential spaces with workplaces, shops, and offices in a single building.

The project features 44 privately financed rental apartments and 6 units for temporary living. About 30% of the total floor space is dedicated to commercial use, including a Montessori school and a creative workshop for people with disabilities. The building is divided into two staircases connected by a semi-public stairwell called the "scala publica," which houses a cinema, library, and gallery.

Wohnen im Grünen Markt emphasizes community living and sustainability. It offers extensive shared facilities, including a community kitchen, laundry room, sauna, yoga room, and rooftop terraces with urban gardening infrastructure. The project follows sociocratic principles, enabling democratic participation among residents.

The housing complex is designed with a strong ecological focus, featuring energy-efficient construction and sustainable heating systems. Its location in a mixed-class neighborhood contributes to the city's goal of creating viable, diverse communities. Wohnen im Grünen Markt represents a successful model of collaborative housing that balances communal living with private space, offering residents a unique urban living experience.
