In the context of negative consequences following an economic growth paradigm, in the urban sphere, such as uneven urban development, marginalization, gentrification and austerity measures, the present study directs the focus towards the spaces of civic promise. These spaces have the potential to challenge the commoditized and consumerist urban practices and imagine alternative futures. The present paper applies an infrastructural approach to neighborhood art spaces with the purpose of identifying and understanding urban solidarity. Urban solidarity is conceptualized as civic sociality that negotiates difference. To pursue this line of inquiry, the thesis analyzes practices, relations, encounters and socialities that are allowed at Konsthall C, a neighborhood art space located in Hökarängen, a southern suburb of Stockholm, Sweden. The three research questions that guide the thesis are discussing the qualities of the art space, the civic sociality and how it negotiates difference and the dynamics between the qualities of the spaces and the civic social relations manifested in the space. These dynamics reveal that there is not a simple straightforward relationship between the two. Moreover, the importance of the background is reiterated for these types of spaces. Besides this, a nuanced perspective on the types of civic sociality and how it works towards negotiating differences is highlighted.
