“Floating developments aren’t just a backup plan for climate change; they’re innovation platforms for decentralised energy, housing, and community.” Rutger de Graaf
For over 18 years, Rutger has been leading the charge in designing, engineering, and implementing floating infrastructure in the Netherlands and beyond.
This episode delves deep (pun intended) into how floating neighbourhoods, ports, and even social housing could redefine our relationship with water—and why this isn’t science fiction but a rapidly emerging reality.
🌊 From Fight to Float: How Dutch engineering is shifting from battling water to embracing it—and how other coastal cities can follow.
🏘️ Floating Cities 101: What they are, how they work, and how they’re being built today.
🧪 Innovation Meets Ecology: The hidden ecosystems growing beneath floating platforms, and why they’re good news for biodiversity.
⚡ Decentralised Resilience: Why floating buildings can be more energy-efficient, flood-resistant, and self-sufficient than traditional ones.
🏗️ From Luxury to Inclusion: Blue21’s pioneering work on the world’s first floating social housing complex.
📈 Tipping Points & Tech Curves: Rutger shares why we may be near an inflection point for global adoption—and what’s holding us back.
📢 A Call to Policymakers: Why mayors and urban planners must show leadership now if we want cities to truly adapt to rising seas.
