The Open Call enhances the quality of public buildings and of the public space, and thus of our environment. The results are visible today. In the 1990s, there were hardly any government buildings in our country that architecture critics or the general public were enthusiastic about. In part thanks to the Open Call, a positive change in the public building culture took place in Flanders at the turn of the millennium. Drawing on selected archival material, accounts and new installations, this exhibition presents a crosssection of the Open Call projects from the past 20 years. It shows how the procedure works exactly and what is at stake in the process.
