**Abstract**

Social housing functions are interrelated in manifold ways, expressing different needs and preferences of heterogeneous and socially unequal modern societies. The home as a place of individual shelter and privacy and as a node of interaction in social networks interferes with activities that had been spatially outsourced in the past and reintegrated again in recent times, such as productive labor, care or supply. In addition, social housing functions compete with economic functions of capital accumulation and profitmaking, transforming the dwelling into a tradeable commodity. Likewise, ecological functions of saving land and resources and reducing greenhouse gas emissions have to be satisfied. These interdependencies challenge sustainable housing politics, most prominently signified in the UN's Sustainable Development Goals 1, 10, and 11. The contribution captures this network of housing functions by advocating to strengthen social housing functions against economic functions. Political and philosophical justification of this position refers to theories of social capital and relational justice. Political measures feasible of being applied within the neoliberal system will be delineated, aiming to sustain social housing functions.
