The Reykjavik WaterWall is aninhabitable sea wall that prevents the city’ssoft bedrock shoreline from washing away intothe strong currents of the Arctic Ocean. Inorder to intercede between the currents andvaluable shoreline real estate, in a city whosepopulation is destined to increase rapidly asthe global climate warms, the sea wall createsa permeable barrier. The barrier’s geometrydeflects currents yet allows other systems topass through, such as organisms or recreationalboats. At key moments a new type of shorelineis constructed anticipating new ports for achanging global shipping network.The WaterWall combines shoreline protectiveinfrastructure with recreation and transportationby creating a mixed use path on top of oradjacent to the wall which looping the entirecity, and modifying based on specific locations.It links to residential neighborhoods, bus routes,and existing road networks through a series ofnodes. The nodes serve as mediators betweenthe city and the ocean, and as an access pointto the wall. “Wet” nodes contain a series ofgeothermally heated bathing pools that stretchinto linear swimming pools embedded in the seawall, transforming the archetype of swimming.The goal of the project is to create public spacewhich can be inhabited immediately with aninfrastructure that provides long term protectionand possible future expansion for the city.
