bruna studio Converts Single-Family House into Two Units in Germany

In Germany, bruna studio has completed the conversion of a single-family house into two separate residential units, a project finished in 2025. The 320 m² renovation was curated by Nina Vuga and photographed by Lisa Hempfer. The lead architects were Lea Mittelberger, Lisa Hempfer, Janna Radlow, and Johanna Herzog. The project addresses Germany's housing shortage, where approximately 13.5 million single-family homes are occupied on average by fewer than two persons, while the country faces a deficit of around 1.4 million housing units. Many residents remain in large homes despite changing life circumstances. The architects argue that converting parts of these houses into two units would significantly alleviate the housing shortage without requiring costly, resource-intensive new construction. The project falls under residential architecture, houses, and renovation categories.
