About the project

The "OstStern" project in Frankfurt represents a significant urban development on the site of the former Mercedes-Benz headquarters, which has been transformed into a vibrant mixed-use neighborhood, located close to the European Central Bank. The development is an extensive and ambitious project aimed at revitalizing a key area of the city while meeting the growing demand for residential, office, and hotel spaces in the region. Covering a total site area of approximately 19,000 m², the project encompasses a gross floor area of 65,000 m². This includes a variety of residential buildings, a social housing block, office spaces, and a hotel, making "OstStern" a significant addition to the city's urban landscape.
A key component of the "OstStern" project is the section which focuses on the design and development of a residential complex within the broader site. It covers a floor area of approximately 20,000 m² and consists of a total of 241 flats. These flats are distributed across a closed city block, with one separate building located within the inner courtyard of the block, creating a sense of community and privacy while still connecting with the surrounding urban fabric. With 241 residential units, the designed section of the 'OstStern' plays a central role in the further development of this important location in Frankfurt. The project serves as a model for contemporary urban design, combining functionality, aesthetics, and environmental awareness to create a high-quality living environment for residents while also contributing to the broader revitalization of the area.
