thank you for the input. I'm aware of the problems with rot at the log bases, I'm hoping the stem wall, a generous roof overhang, and curing the wood properly should prevent that. For insulation im planning on using either sawdust & lime or hemp hulls & lime in between the logs & the interior walls, which will be a earthen plaster over a bamboo lattice, im also planning on hempcrete blocks between the floor joists for floor insulation.

Hello, Im tinkering with an idea in my head, and would like some input. I think building a round vertical log cabin on a stone stem wall with embedded steel strips that would be bolted onto the log bases then I'd have about 6' of vertical log with two 2x6 boards nailed out of the top with bracing. The roof would be yurt style with a central ring and radiating poles that would come down to sit in the boards atop the logs & loosely bolted into place (I want the structure to be able to flex as I'm planning on either getting land in the PNW or Alaska & both get earthquakes). I may carve a channel into the top of the logs (but Ideally hidden by the roofs eaves) & run a steel cable that can be tensioned to provide some compressive force inwards. The logs would be swedish couped with each convex log face fitting into a corresponding con cavity on the next log. I'd chink the logs with a slow drying earthen plaster (probably a "typical" cordwood mix) on the outside & inside. I've never seen a round vertical log cabin, so I'm apprehensive im missing something. Im also curious about what would be a good minimal-concrete foundation for such a structure.
