Pacific Yurt platform recommendation

[chrishallweaver]

We're putting up a 20' Pacific Yurt in the western mountains of Maine. It will be a bunkhouse, 150 feet from our log cabin.

The carpenter I hired, assumed that he'd be building a 16-inch on center platform. Then I looked at one of the Pacific Yurt recommended ways that had a 2x6 finished floor over approx. 4' on center 4x6or8 beams. See attached diagram.

I like the simplicity and low cost of the Pacific yurt plan. But will this floor be too bouncy?
