Round Timber framing - Machine hall (1/3)

Our farm sorely lacks buildings of all sizes and since I had gotten myself an old combine harvester I didn't want it to stand out in the rain and rust more than it already had so I decided to try and build a machine hall in a timber framing style. It's a total cheat, with butt joints, screws, nails and some fortifications, but it was a really enjoyable project. Disclaimer! I am a total noob in building these kinds of buildings so it's testing and cheating and seeing what seems to work. I'm not an expert, don't assume I know this, I am however an exicted do it yourself:er. In the first part I set the foundation, fell the logs, builds to frames/portals and tries to raise them, but I was in over my head.
