Real estate is struggling with a problem: there is an empty school building in Hoogvliet where something has to be done. Developers are not very enthusiastic about the piece of real estate, because it is in a challenging and risky area in the city. It is promising that the hackathon will take place during the Transformation Congress in De Doelen, where many developers are walking around. During the congress a special group of students from different backgrounds, including medicine, biology, architecture and environmental technology, did their best to carry out the assignment. The students work hard to pitch their solutions during the last plenary presentation. The public will have the opportunity to vote for their favorite solution and indicate whether they would like to be involved in the redevelopment of the building. To the satisfaction of the customer, 65% of the room voted ‘yes’.
