110Advancing sustainability and circularity in the built envi- ronment requires a coordinated, inclusive approach that spans both the early planning stages and the end-of-life re-use of buildings and materials. Embedding circular principles into Phase Zero – the early-stage planning process – ensures that urban development is not only resource-efficient but also culturally resonant and eco- nomically viable. By integrating sustainability, adaptive policies and inclusive stakeholder engagement, Phase Zero creates the conditions for high-quality Baukultur and sustainable, resilient cities. At the same time, prior - itizing end-of-life re-use practices allows for the strategic repurposing of materials and structures, contributing to a circular economy and reducing environmental impact. The Davos Baukultur Alliance calls for collective action to embed these practices into global urban frameworks to drive transformative change and ensure that cities of the future are resource-efficient and culturally resonant.Conclusion The innovative practice studies present a series of examples of key approaches for advancing both Phase Zero planning and end-of-life re-use practices. These showcase innovative strategies that promote sustaina- ble and circular Baukultur within the built environment. These projects demonstrate how high-quality outcomes can be achieved when urban development embraces sustainability, cultural preservation and collaboration from the outset and extends these principles through adaptive re-use at the end of a building’s life cycle. By addressing challenges such as stakeholder align- ment, adaptive policy frameworks and circular economy integration, these studies highlight diverse approaches – including participatory decision-making, land and building re-use and forward-thinking policy adoption. Rather than prescribing one-size-fits-all solutions, they offer adaptable models that respond to specific local contexts, ensuring that both early-stage planning and end-of-life re-use strategies are scalable, inclusive and impactful. Together, these case studies provide action- able insights and inspiration for cultivating resilient and resource-efficient urban development.Innovative practice 111Unsplash
