As an accessible and low-risk mode of transportation and recreational activity, walking both produces and is produced by socio-spatial urban features. The health benefits of walking transcend physical fitness, remaining integral to mental health and to fostering social connectedness in urban communities. Understanding what drives walking behaviour, therefore, warrants attention from a public health perspective. This qualitative case study focuses on the social interactions of inhabitants during neighbourhood walks and how built environment features influence walking patterns and experience. Using diaries, maps, and semi-structured interviews with 45 inhabitants of a mid-sized Canadian city, this research investigates the influence of permanent and temporary physical features on the perceived quality of inhabitants' walks. The findings show the public visibility of urban modifications influences walking behaviour and improves social interactions, leading to a heightened sense of belonging and community. Inhabitant-led modifications in the urban space were mostly neighbourhood-bound and voyeuristic, whereas administrative interventions were more successful for collectivization. Both types of interventions are argued to foster social connectedness through different mechanisms, with positive impacts on inhabitants' health and wellbeing. The findings underscore the relevance of community-led and administratively planned interventions in built environments in positioning public health policies associated with social cohesion and connectedness.
