I live in Denmark, and can say there are many ways people do it here. Most common (from what I have seen as an American here) is to own a small business and use it to shift around ownership of things such as apt's and cars as tax on business is very different than personal...Google Danish car tax for more info on why.

Sell up and buy stuff abroad.

Or, since you mentioned above that the tax is on net property ownership, get a loan in the UK to the amount you own there, and buy stuff abroad with it.
