World Expos are ‘world known’ events, with its core business to meet, learn and innovate. The national pavilions specially build for these events are outstanding architectural structures to show off the visitors and the rest of the world. What many people do not know is that the post-use of these structures and the surrounding area are in many situations not optimal and sometimes even abandoned. The Dutch Pavilion designed by MVRDV at the Hannover 2000 expo is one example of this disrepair. The post-use of these specific areas could be more optimal in use and with that even support the local urban and economical development. This research brings you in the complex world of urban area development specifically with the use of a World Expo. Such events are nowadays more and more used as a catalyst for large development projects and for the promotion of the city. This recent initiative should be examined. This research will take a critical look into literature studies and two complying World Expo cases are investigated on their post-use strategies. The result of this research includes a strategic plan which can serve as an advice to future host cities of World Expos how to implement an optimal post-use strategy for these World Expo areas.
