The theme of this work is the analysis of (un)successful processes of gentrification shown through case studies of the former factory Paromlin and the hybrid house for art and people Lauba. For the case study of Paromlin I am referring to the theories and case studies about gentrification, that show her as a negative process. In the case study of Paromlin I present his history and the problem of his history not being shown publicly by the city of Zagreb. I present the gentrification of Paromlin as an unsuccessful process because of the City’s plan to demolish the building and build a new public library in its place which is an example of negative gentrification of space. Through Paromlin’s case study I present the media and personal blogs as critics and carriers of Paromlin’s history and as a space of creating resistance towards the gentrification of Paromlin. The case study of Lauba I represent as an example of successful gentrification through which I present the concept of revitalizing gentrification. The building in which Lauba is today is a former military stable of Austro-Ungarian monarchy, later converted into Textile combine Zagreb. Being bought into private ownership, the building is converted into Lauba. As a house which represents contemporary art of artists of different generations, Lauba approaches their works to a wider audience of public and creates a hybrid space which “shifts” for every exhibition. Lauba preserves the history of the building all the while, via her workers, written pamphlets and the revitalization of the building, which makes her a rare example of successful gentrification.
