>>1818911Fascist Spain had done great in that regard: they promoted dense urban development (and home ownership over renting for good measure) and as a result today the overwhelming majority of Spaniards live in apartments they own. To be fair it was done to preserve farmland for agricultural autarky more than anything else but who cares the end result is the same: dense cities and lots of empty /out/ space.
Nowadays though the liberal, democratic, homosexual Spain is slowly undoing this, where most new neighborhoods comprise detached or semi-detached houses. So take that as you will.
