The Cattenbroekerplas, originally dug as a source of sand for the creation of the nearby highway A12, is currently used for recreation. The development of a new neighborhood in the proximities justifies the improvement of the spatial qualities of the lake, like creating a new beach area and introducing recreational facilities. The design consists of an embankment that acts as a buffer against the negative influences of the nearby highway, a building to house the recreational facilities with a terrace towards the water, a beach site with a lawn, an event area and the necessary car and bicycle parking facilities on the southern bank of the lake. The eastern bank is transformed into an ecological zone of water and reed land.
