Newly built urban environments are a prominent feature of contemporary Swedish cities, yet are often experienced as anonymous and difficult to feel belonging to. This study examined which physical and aesthetic characteristics of newly built urban environments in Gothenburg co-vary with experiences of placelessness, how these experiences vary between different types of urban environments, and how they relate to individuals' attachment to the city.The study was based on a quantitative survey of 98 respondents, distributed through Gothenburg-oriented groups on social media. Respondents assessed photographs of four newly built urban environments: Kvilleb?cken, Masthuggskajen, Fixfabriken and G?taverken using a placelessness index derived from six statements on a five-point Likert scale. The physical and aesthetic characteristics of each area were coded by the researcher along three dimensions: scale, level of detail, and compositional order.
