Log as a column

[Mårtesgården]

I'm thinking about what it would be like to have a whole, debarked, log as a pillar. They would then stand on the slab and go all the way up to the ridge. The floor for the second floor and the floor for the attic would be attached to the logs.
How would I attach the log to the slab?
Will the log shrink and if so, how could I adjust the construction afterwards so that the floors and ceiling do not lower?

Dry the logs so they contain approximately 7.5% moisture content before assembly, this will help you avoid any problems with shrinking/movement. If you do this, there probably won't be many problems regarding the posts.

Fasten the log with 2-3 guide bolts into the slab, i.e., 2-3 bolts that are in the log and guided down into holes in the slab.

Best regards, Jawen

7.5% moisture in a log. Is it possible to reduce the moisture that much without drying?

There are brackets for height adjustment. It is basically a threaded rod with a nut. I think I saw it at Swedol or Jula.

Yes, but that assumes the post doesn't attach anywhere in the middle. Because if the post shrinks evenly over its entire length, the floor that is attached in the middle will be too high once you have screwed up the post so it fits at the top...
Or have I missed something?

The length of wood doesn't change that much, it moves mostly in width.
