I wish I could restore some of those houses, especially the one made of logs! Most of them are probably constructed the same way under they outer layer...
I've worked a tiny bit on things like that, on wood since I was a kid, including repairing the keel of my first sailboat, its very rewarding work!
Also sometimes it can look like its beyond repair, while the opposite is the case, if there is no mold and not too much rot its often all about straightening it out using jacks, pulleys and so on to start with 🙂
