Your global leading expert in floating architecture and urban development.

We design, research and realize floating projects in delta cities across the world. Our belief is that we must shift from sustaining our planet to restoring it. Floating urban development can make cities more resilient, create space for new eco-systems and enable bio-based economies to flourish.
