Motivated by accelerating biodiversity loss, this experimental project explores whether more-than-human participatory design can help support sustainability transitions in urban systems. In particular, the experiment responds to smart neighborhood developments that prioritize technological efficiency and human convenience, while biodiversity and more-than-human needs remain peripheral. To research this, the project focused on qualitative research and evaluation through workshops in which participants became bats for an evening, searching for a place to live in a smart neighborhood in Kalasatama, Helsinki, Finland. The workshop aimed to assess whether inhabiting an animal’s perspective can shift perceptions of what constitutes a good urban neighborhood. Findings suggested that immersive, morethan-human role-playing can alter how participants perceive and value urban space. When framed as a context-sensitive niche experiment, the workshop offers a repeatable and adaptable prototype that could inform transition planning, community engagement, and urban design education, and contribute to longer-term efforts to reimagine urban environments as mutually beneficial shared multispecies habitats.
