Yeah, as a Kiwi, I get very envious of housing quality when I travel to Europe. That said, we are (belatedly) fixing the problems in new builds at least, and there have been attempts to bring our rental stocks up to scratch in terms of insulation, but the issue being our centre-right government really doesn't like rocking the baby boomer boat (who make up the majority of our landlords), and so went for a carrot with no stick solution.
