Yurt Deck Sizing

[North Central Washington]

Recently I inherited a 30 foot yurt along with the deck it sits on. Care was taken to create a tight fit on reassembling the 1/12 by 6 tongue and groove deck board. Consequently the result was that the diameter across the boards wound up being 29 feet 7 3/8 inches or about 5 inches short of the 30 foot recommended diameter. My question is whether or not this will ultimately matter if I were to go ahead and raise the yurt itself on this platform or will be the yurt be forgiving enough to adjust to this discrepancy. Or – do I need to somehow make sure I add the 5 inches?

I would extend the flooring, and give the walls solid anchor. It will pay off in the long run.

Jafo is correct. While the bagana interior ring support posts carry some of the roof load, most of the weight of your 30' yurt is bourne by the floor under the wall. You could try erecting the yurt on the existing platform. My guess is there will be misalignment of rafters to roof ring and cover to rafters. Yurts are built to a specific diameter. Good luck.
