do you call it 'going rooming' then as we call it 'going flatting' to indicate that someone is moving into a flat?
A flat could be a shared house, or a shared apartment, but most people dont actually share apartments. Apartments are mostly inahabitated by single people alone or couples as they are so tiny that there isnt really room to even share, while most homes are shared.
we had a housing shortage in the city but now the laws have changed a bit to allow more housing to be built, mostly cheap houses that will fall apart in a couple of years, ugly apartment blocks, and future slums...
thry arent even affrorfable really because they are privately owned and the landlords always charge market value. And the demand is high.
However people need living space rather than live in the garage or 4 to a room. Lots of backyards are being filled in by townhouses. However this is putting a huge strain on services like roads, sewerage and stormwater, as the old infrastructure wasnt designed to cope.
