In just a few decades, a sea change of Sydneysiders have ditched traditional houses with a backyard for apartments in the superstrings of new high-density blocks lining the city's main public transport corridors. Where once there might have been a three-bedroom house over 1000sqm with gardens front and back, developers may now offer a cramped studio flat squeezed into 40sqm, barely bigger than a motel bedroom. But between 1991 and 2021, the number of people living in Sydney units more than doubled, with 30 per cent of all Aussies now calling apartment blocks home.
