DIY is quite Swedish. Not uniqly Swedish, I can't comment on that, but historically (until end of the 80s especially), the income tax levels made it so expensive to pay someone else to do things such as paint your house, renovations of various kinds etc, that people either did it themselves, or paid someone to do it "without receipt". There was a tax reform around 1990, that put a more reasonable ceiling on taxes on labour, and later also additional tax exemptions for some renovation work, which turned a black economy more white. Today it is much more common to pay for home renovations, but I think a DIY culture remains.
