Yurt floor size

[TurtleKate]

Hello fellow circle lovers,

I have a 5m mongolian yurt that I am putting up on a 6m platform cut into a hillside. We would like to have some room to move around the yurt and were planning on building a large deck about 7m x 6.5m to put the yurt on. I understand the yurt canvas has to hang down to prevent water coming in. We were suggested to do a secondary raised deck above the first, which would effectively be a 'waste' of the timber on the main deck, but would have an added

insulation

factor. The other thought was to cut a circle into the deck so the edge of the canvas fell through the boards and onto the joists.

My question is this: What is the best way to put a yurt onto a deck that is larger than the yurt footprint?

Thank you!
