For cost and convenience, we opted for concrete pilings and box beams for our foundation. The concrete pilings are 4' deep by 12" wide and were poured in less than an hour.
The box beams are basically doubled-up 2x12s and are incredibly heavy-duty. They are bolted to the concrete pilings with 1/2 inch anchors.
We used 2x10 green-treated for the joists and capped the whole thing off with 5/8 treated plywood.
Other than some lattice, which will be installed later, we opted to leave the underside open for air-flow and to prevent moisture damage underneath the cabin.
