The COVID-19 outbreak and associated lockdowns have heightened the challenges of social isolation in urban communities. Social interaction is recognized as a key factor in promoting people’s health, wellbeing, and social sustainability within urban communities. Public open spaces serve as a vital link between communities’ environment and individuals’ wellbeing. However, there has been limited research exploring how community parks impact residents’ social interaction in urban communities during the pandemic, particularly a lack of in-depth qualitative research in this area. To address this gap, this research investigated the impact of community parks on social interaction in master-planned communities in Sydney, using a qualitative case study method. A total of sixteen residents living in two selected communities—Breakfast Point and Liberty Grove—were interviewed during the COVID-19 pandemic in 2022. It was found that three themes and seven underlying subthemes of park-use factors influence residents’ social interactions: (1) quality of park spaces (rest spaces, BBQ/picnic recreation spaces, children’s playgrounds, sport facilities, and nature amenities), (2) pedestrian integration of parks (interconnected park network and well-dispersed small parks), and (3) pedestrian connectivity with surroundings. The findings provide theoretical, empirical, and practical implications for promoting social wellbeing and community sustainability in the post-COVID era.

There have been growing concerns regarding increased social isolation in Australia, many of which are currently being exacerbated due to the COVID-19 pandemic. Feelings of social isolation may increase the risk of mental issues in people. New Urbanism hypothesizes that neighborhood communal spaces can influence social interaction between residents and, in turn, can promote community sustainability. This study investigated the associations between community parks and social interactions in master-planned estates (MPEs) in Sydney, Australia. Data were obtained from a resident survey conducted in two MPEs in the inner west area of Sydney: Breakfast Point and Liberty Grove (n = 192). Hierarchical multiple regression (HMR) models were used to analyze the relationship between community park use and social interaction. This study found that the factors ‘frequency of community park use’, ‘rest spaces satisfaction’, and ‘pedestrian connectivity with surroundings’ are significantly and positively associated with social interaction between residents in the MPE context. The findings of this study highlight the importance of the community parks in creating social sustainability in MPEs, particularly in the context of COVID-19 pandemic.

Master-Planned Residential Estate (MPRE) is an integrated housing development form in Australia. MPREs are aimed to build a sense of place attachment and community via the provision of environmental and social infrastructure. Neighbourhood parks are regarded as a significant built environmental factor linked to residents’ place attachment and well-being in the literature. Understanding place attachment is crucial for promoting residents’ well-being in neighbourhoods and enhancing the attractiveness of real estates in the housing market. However, we know little about how place attachment is facilitated for park users in neighbourhoods. The psychological process of place attachment in MPREs is unclear in the literature, with a particular lack of qualitative studies in this area. This study explored the psychological process of place attachment and its associations with neighbourhood parks in MPREs in Sydney via a qualitative case study. Semi-structured interviews were conducted with 16 residents residing in two selected MPREs in Sydney during the COVID-19 pandemic in 2022. Interviews found three themes and several subthemes regarding the process of place attachment for park users in MPREs: affect (emotional bonds), behaviour (place-related fulfilment of needs, place-related social bonds, and community participation), and cognition (membership of the community, place-related memory, and cultural significance). This study contributes to understanding place attachment and human-environment relations in sustainable neighbourhoods by adding new items into place attachment models from the perspective of MPREs in Sydney. It provides valuable qualitative evidence gathered during the COVID-19 pandemic. The findings furnish empirical insights for policymakers, developers, and urban planners involved in sustainable neighbourhoods’ development and housing management in Sydney and global regions.
