As the winter has set in, fishing season is over and a stay at home order has me thinking about projects for the spring. I have been wanting to build a little guest cabin on my property for years now. I would like to build a round house with stacked wood walls. I have a great deal of White Cedar that I have been saving for posts and beans as well as the walls. I think I have everything figured out but the foundation. I was originally going to just sink sonotubes but the area is full of roots and big rocks. It is going to be a bit of a nightmare to get them all in and lined up for a round house. I have now been thinking about a floating slab on grade but cement work is not something I know a lot about. I am in zone 5 in Ontario Canada. Please let me know your thoughts.
Sounds like we are somewhat in the same boat. I'm looking to do something similar, and can recommend the cordwood building books by Rob Roy. A floating slab would be an option. My aunt and uncle in Ohio bought a home that was built with Cordwood on a floating slab. Another option would be rubble trench.
Both of these options would require drainage and frost consideration.
One method I've been considering is to use a pier/pile/sonotube style feet for the frame and then a rubble trench to carry the cordwood and build it in a way that would take settling into account.

One idea would be to dig post holes wherever you can and then plan the shape of the building from there. Square, parallelogram, octagon, etc

Steel screw-piles? No digging, likely to go right through roots... LARGE rocks/bedrock would not be optimal..
