50' yurt. Is it a good idea? What Would it Cost to DIY?

[Kintore]

I've just begun looking into building/buying a yurt and I'm convinced I need a 50'. I would love to build my own but, I'm open to manufactured and delivered cost estimates also. I'm looking for a ballpark price on the basic structure and platform that's basically fully loaded, meaning full snow and wind package, 2x6 framing, vented

with screen and fan, long life fabrics, and nice doors. I would also like a reason catchment system. I'm not crazy about the traditional gutter system due to snow in the winter. Thank you for any input.
