Co-Designing with Nature: How Communities Are Becoming Stewards of Urban Biodiversity

The concrete canyon of Melbourne's Degraves Street was once a stark service corridor in functional obscurity. Today, the narrow laneway now pulses with life beyond its famous café. Native grasses cascade from carefully positioned planters while small shrubs create cooling microclimates. Challenging traditional ecological design models, community-led approaches to biodiversity invite a reimagining of how architects, planners, and communities collaborate to develop biodiverse urban futures.

Cars dancing endlessly round and around, drawing inaccessible circular spaces punctuating our cities, looking for meaning. What about roundabout what?

The Deutsches Architekturmuseum (DAM) in Frankfurt has opened a new exhibition titled Building Cities Today?, examining the complexities of developing new urban neighborhoods in Germany. Running from June 28 to November 2, 2025, the exhibition brings together nine projects that reflect diverse approaches to new urban planning, with a focus on sustainability, social integration, and long-term adaptability. Referencing the legacy of the "Neues Frankfurt" housing program of the 1920s, the exhibition opens with the Römerstadt estate, one of Germany's early experiments in functional and standardized housing. From there, it transitions to eight urban developments from the 1990s to the 2020s, presenting case studies that include HafenCity in Hamburg, Bahnstadt in Heidelberg, Neckarbogen in Heilbronn, City of Wood in Bad Aibling, and Messestadt Riem in Munich.
