I would have to check on the overhang, but I'm sure it is following Iowa building codes and has to be at least 3 ft or more. There are gutters on the house just like my house so the water would not splash any more than the natural rain. I know the logs are all preassure treated originally, and have a special stain/sealer to prevent moisture problems.
As for the foundation, the front is the only part close to the ground. The sides and back have no issues as it is built on the side of a hill and has a walkout. Iowa gets snow and is a very cold climate, we are not that far from Canada. I'll ask him about the snow issue in the front of the house and inspect the logs.
I'll ask about the beams, but I would think a builder that only builds log homes would know that, not sure, maybe they are shady.
The gable ends are another question I'll ask about, thanks. I will also try to find out how the interior walls are done.
thanks again, Randy
