Brainpark I is a monofunctional business area along the highway A16. The challenge is to transform the site into a vital and interactive work-and-live area that’s well connected to the nearby the Erasmus University Campus and the public transport hub Kralingse Zoom. Submitters must come up with a densification strategy that unlocks its productive potential. The main question is: where to begin? What are the first actions to be taken? A cross section of the site with several architectural interventions should give an impulse and a direction to the transformation of Brainpark I.
