Thanks to everyone for the info they have previously shared on cabin building, moving logs, etc.
I don't see too many cabins (any really) made with birch logs, I can guess that is because they are heavy, skinny, and it's hard to find straight trees.
The forest in my backyard is in the birch stage, with the spruce trees still only 10 feet tall and spindly as they fight for sunshine. So with all this birch, why not build a small cabin in my backyard? I could practice my notch scribing skills, experiment with a foundation idea I learned on this forum. I know I would learn a lot, and then when I eventually head out to my remote property, it wouldn't be my first time building, which would save me a lot of time and cost.
Ok so long question short, why not birch logs?
