Architecture of Appropriation. On Squatting as Spatial Practice’ acknowledges squatting as an architectural practice. The publication analyzes a series of case studies through architectural drawings, interviews, and archival material to build up a record of past and current struggles, morespaces, and oral histories, forming the basis for a new acquisition policy for the State Archive for Dutch Architecture and Urban Planning. The project brings the expertise of the squatting movement together with architects, archivists, scholars, and lawyers, to discuss approaches to the research, archival practices and representation of precarious, non-author-based, and often criminalized spatial practices in the institutional framework of an archive and museum.
