Since 2009 OKRA has been working on the coast defence at Katwijk. In early 2014, the construction started of this unique project. First, two million cubic metres of sand were dredged to create the new form for the coast. Subsequently, the construction of the dike and the public space began. At present, the construction of the underground car park in taking place. Once this phase is complete, the dunes and paths will be laid out over the garage and dune landscape, along with a dune boardwalk and beach square.
