Thank you for your message.
You're right. It is just a pillar on top of a stone.
This is the traditional structure of Japanese houses, but it is rarely used nowadays because concrete foundations have become the mainstream.
However, all of us involved in this project, including myself, love Japanese architectural culture, so we adopted this structure this time.
It's fascinating thank you so much for sharing these pictures. The various portions of the construction interest me very much as they would be adaptable for a pole building I'm planning. The construction process you have shown is very logical and approachable. The craftmanship is stunning. The stone and post system would not work in this soil type. We have expansive clay so posts are buried into the ground. Thank you for sharing this story.
Indeed, the ground here is very good. That's why this stone foundation structure is possible. Of course, there is compacted crushed stone under the stone to support it.
I hope your project will be successful.
Thank you for adding more detail. It's a beautiful dwelling you have built. I really enjoyed seeing it
