Yurts are little round houses that were very trendy with the flower children back in the late 60's - early 70's. A lot of the hippies moved to the country and built yurts.
They're round and sturdy and made of wooden slats and nomadic people used to live in them. They used to be made by hand in the 60's but you can now buy them on-line.
They were hippy-dippy things.
Like a geodome?
Sorry for the off topic comment, but every time I see that term I think about the 'Dharma and Greg' show. "She's a hippy-dippy flower child out to save the world...he's conservative." That's not the exact wording, but close.
