The project aimed to encapsulate the identity of Rijkswaterstaat in a sustainable building that manifests the organization’s core activities. The Dutch public works bureau is responsible for the roads, the waterways and the landscape, so each of these areas is distinctly represented. The south facade of the building is a mass of concrete and asphalt cut with horizontal openings. This solid wall is designed to block the sun’s heat and the noise from the adjacent highway (which they ironically constructed). Designed with grooves and patterns, the south facade is an abstract representation of a highway. Over time, rainwater from the roof, which is directed over the facade, will encourage growth of moss and plants, making the facade less stark.
