Spent last summer building a one room log cabin.
In the end I wound up using makita battery powered chainsaw. You can do precision work and quickly too.
I did not have any skill before and my vacation was short, but theres now a 5' by 12' cabin, 8' tall, on my yard.
This summer it's the floors, roof etc.
The video is much cooler of course, just saying if you want to try something with limited time.
I had help every now and then. Looking back it's a project for two people definitely. Logs are heavy and having four eyes is better than two, especially as a beginner.
