The TOH article focused on yurts built by an outfit called Pacific Yurts. The company claims that their structures can be used year-round in just about any location. The packages they sell start out at about $4,100 (US) for a 12 foot diameter yurt; all you’d need to provide is a platform to put it on. You can also choose larger yurts (with larger price tags, of course) and add all manner of options to them to better suit your needs. Their website has some neat interactive stuff on it, like the “Virtual Build” Flash presentation, and the Price Quote sheet.
Ok, so the yurt may not be a terribly practical structure for human habitation. But you’ve got to admit they are kinda cool. And I just like the word “yurt”.
