Hi,
I've done several floors, in various ways, for low or no money. My yurts are coppiced, so light enough to be able to lift the walls if necessary. So they'd be fine for installing a floor after you've put it on a ply subfloor. I guess you'll be treating the floor afterwards, so you'll need to be careful with the product (if coloured), or live with a few splashes on the bottom of the walls here and there.
The floors I've done (reference here:
https://thedevolutionary.wordpress.com/?s=yurt+floor) have all been finished before the yurt goes on. It takes me two days on my own to put down an 18-foot floor made of 10/12 cm tongue & groove. If you go for wider, you'll cut that time down a bit. Then treatment takes a day or so (for two coats). Then the yurt a couple of hours. I've toyed with the idea of an adobe floor with underfloor
, but never done it - and when we considered it, I remember thinking it would take weeks. And would need to be covered. And not too hot. And and and. (And I've read it would be wonderful.) You'll find yourself looking at the weather a lot when living in a yurt - and racing the rain/snow/whatever. Where I am, a rain-free week comes along quite regularly. Actually, a bit too regularly now.
The only ballache I see with installing your floor after is cutting the circle segment on each piece as you go. As you'll see from that reference, I tend to put the board down, cut it, move the board to the other side, put it down again, and cut off the triangular shape, for as little waste as possible. These become kindling, but a triangle is a bit tricky to split, as you may find.
Good luck with it.
