Interstitium is developed as a semi-fictional archive which records unrealised, unfinished and undeveloped projects in urban space. The collected material consists of 526 files classified in 10 provisional units consisting of open calls, master plans, individual architectural projects, relevant academic and newspaper articles and additional documentation concerning the selected site, Slavija squere in Belgrade.

Although it assumes the form of an archive, the work is developed in diverging from official archival procedures of mastering and storing the past. Made from the documentation about the unrealised and the unachieved, it functions as an archive only conditionally, since it does not account for past, but possible events. In addition these events are processed in a nonfactual and nonlinear fashion and furthermore fictionalised through various interventions, thus leaving out the effects of historical accuracy and integrity. The interventions include decontextualisation, fragmentation and manipulation of the collected material along with the fabrication of objects and documents as potential artefacts of the site. Through such mismatchings this archive places itself not as a collection of memories and experiences, but on the contrary, as a collection of their absence. It operates with the documents of possible memory and parts of unfulfilled histories of one locality. In this context the archive does not give actual information about the particular urban site, rather it records its movements between utopian projection and social contingencies.
