Platform structure question

[elewis33]

I'm about to build my

yurt platform

and I'm following the suggested plans from

Colorado yurts

, about platform framing,

insulation

and subfloor. My question is about the

insulation

layer.

I'm planning to put OSB on top of the joists, under the

yurt platform

, to tie the joists together. On top of that will be the platform framing, insulation (blue layer in the image) and subfloor. I'm showing the floor framing extending beyond the perimeter of the platform, but those will be cut back to the diameter of the platform.

My question is: should I just put the insulation panels directly on the OSB and build the framing structure on top of the insulation layer (see image)? Or should I put the framing directly on the OSB and put the insulation between the framing?

I like the idea of putting the insulation on the OSB and framing on top of the insulation, because it will be a continuous insulation layer, uninterrupted by the framing. But wondering about how to attach the floor framing to the insulation layer if I take that approach?
