This FOR SALE sign was displayed near the Buddhist Temple at Banjar Hills when I visited in 2010. Balinese friends had taken me down into the hot and windless valley to look at this "villa" which was owned by a Dutchman who came out once a year to live in it.
There was no path to get to it; instead, we had to cross a river by jumping from bolder to bolder and trudging through muddy rice paddies.
Anyway, it has now been sold. I don't envy the new owner living in this remote and hard-to-get-to location.
