Biodiversity is at a critical juncture, and the built environment holds both challenges and opportunities. As climate change, urbanization, and habitat loss evolve globally, architects and designers must ask how their work contributes to — or mitigates — these forces. The challenge is not merely aesthetic but ecological and ethical: How can the built environment support complex life systems rather than erode them? In 2024, we launched a research initiative to investigate this question and to explore how biodiversity can take a larger role in architectural design practice. The resulting insights offer an accessible entry point for integrating biodiversity into design through measurable, impactful, and scalable strategies. Drawing from regulatory trends, scientific best practices, and emerging technology, we identified biodiversity as the next frontier in sustainable design.
