Just a thought and I know it's a bit "swings and roundabouts" but some of the Cordwood builds I've seen seem to actually make better use of the different sized logs to make the walls.
I guessing the wind direction would make a difference for the siting of which way the door and window should face. I built a stable for the horse we owned and was all set to fit the door facing south west. Locals came along and told me to face it North. So pleased I trusted their input because all the strong winds and driving rain blows in from the south west while the north stayed sheltered. Little things like that can make such a difference.
Sorry to sound as though I'm interfering by suggesting stuff, such as the cordwood website. I'm just trying to offer you alternatives to the usual log cabin type construction. This is your build and I look forward to seeing what you make of it.
All the very best.
they look quite beautiful.
What's the advantage of them over other build types? Just being able to utilise all sizes of wood?
