This article explores the experience of living among diverse infrastructural configurations in Ulaanbaatar, Mongolia, and forms of stigmatisation that arise as a result. In this capital city that experiences extremely cold winters, the provision of heat is a seasonal necessity. Following a history of socialist-era, centrally provided heating, Ulaanbaatar is now made up of a core area of apartments and other buildings undergoing increased expansion, surrounded by vast areas of fenced land plots ( ger districts) not connected to centrally provided heating. In these areas, residents have historically heated their homes through burning coal, a technique that has resulted in seasonal air pollution. Expanding out from Wacquant’s definition of territorial stigmatisation, this article discusses the links between heat generation, air pollution and environmental stigmatisation arising from residents’ association with or proximity to the effects of heat generation and/or infrastructural lack. This type of stigma complexifies the normative divide between the city’s two main built areas. Residents’ attempts to mitigate forms of building and infrastructural ‘quality’ or chanar (in Mongolian) form ways of negotiating their position as they seek different kinds of property. Here, not only are bodies vulnerable to forms of pollution (both air and otherwise), but also buildings and infrastructure are vulnerable to disrepair. Residents’ assessments of infrastructural and building quality move beyond any categorisation of them being a clear ‘resistance’ to deteriorating infrastructural conditions. Instead, an ethnographic lens that positions the viewpoint of the city through these residential experiences reveals a reconceptualisation of the city that challenges infrastructurally determined normative assumptions.
