We are blue21
The first global leading expert in maritime urban projects
We design, research and realize floating projects in delta cities world-wide. Our belief is that we must shift from sustaining our planet to restoring it. Floating development can make cities more resilient, creates space for new eco-systems and enables bio-based economies to flourish.
