“…Apartment residents often report few social connections with other people in their local area (Gifford, 2007;Reid, 2015;Scanlon et al, 2018), desire more than they have (Easthope et al, 2017;Forrest et al, 2002;Thompson, 2019;Hirvonen & Lilius, 2019), and struggle to balance sociability with privacy in their buildings (Gifford, 2007;Reid, 2015). With growing proportions of people living in apartments, even in cities where low-density living is traditionally the norm, this situation is concerning for three main reasons: a lack of local social connection can have negative impacts on a person's mental and physical health (Eicher & Kawachi, 2011); may weaken the ability of apartment residents to work together to maintain and manage their buildings (Borisova et al, 2014;Liu et al, 2018); and can undermine the wider social sustainability of local areas (Dempsey et al, 2011;Sandercock, 2003).…”
