The FlexHubDock is the best example of how Port and City can coexist in harmony. A smart shared surface will allow to use the area of the Port of Barcelona as both a Dock for ships and a public Plaza. In this moment,digital technologies allow us to envision and achieve this kind of solution.The FHD modular/parametrical system, provides an adaptable additivestructure open for future applications in other ports and cities around the world. The FHD project have as main supporters the citizens and aims to offer new possibilities, some perhaps still unimaginable today. A Dock is usually associated as in the limits between the city and the water. But the FHD is able to somehow use the water as land, and transform this land into water, giving the city a whole new layer. Spaces can appear.. ..and disappear!“A dock is always expecting a ship, but this dock does not wait a ship,it performs”.- Willy Müller.
