The COVID-19 pandemic has led to changes in everyday lives through restrictions that resulted in lockdown practices in the home, whereby practices were reassessed, changed, renewed, or newly established. Based on a qualitative study of lockdown practices following the first wave of the pandemic in two European cities with high living standards, Oslo and Geneva, we studied how changes in practices led to need (non)satisfaction and (un)sustainable consumption, demonstrating the significance of social interactions in how practices were coordinated. We then highlight the practice elements that favored or impeded need satisfaction, recognizing what material arrangements, skills, and competencies were necessary. Finally, we discuss the “normative accountability” of lockdown practices in discourse, in that the mutual accountability of various practices during the lockdown revealed the need for coordination between people sharing the same space. We find that social interactions are critical toward understanding how the lockdown practices were coordinated in given space-time configurations. Need satisfaction required grappling with social differentiation, as people with strong social relations, generous indoor spaces, and access to outdoor natural environments experienced higher levels of well-being. This situation has implications for policy making in terms of how societies can be reorganized to ensure “sustainable well-being” as a normative aim.
