Hi from Australia. I enjoy watching your channel even though I can't read Japanese. You have very good woodworking and technical skills. It took lot to drive and determination to continue your project after the rain damage earlier. Well done.👍
You should add a thermometer inside the cabin so your viewers will have a clear idea of what it feels like inside specifically during winter and summer time.
Where are you able to build this? An empty parking lot? You aren’t/didn’t have to be concerned of theft? Seems you are leaving your tools there as well... I understand there are places in the world where people rest each other’s property and theft is of little concern but... I have to know, where were you able to build this in such an empty open lot, with minimal people around with electrical plug in?
