Interesting link. Is it code anywhere in the country to frame like that?
A big part of what I do for a living is correct damage to homes done by improper framing. Most of the time it's using lumber to small for the span.
2x6 studs on 24 inch centers is fairly common and approved, but rarely done because what you save in money for the studs, you spend more for your siding to handle the bigger spacing between studs. But it looks like some of the walls are 2x4's and some are 2x6's? Is that right? Are you spacing 2x4 studs 24 inches apart?
According to your diagram, the corners are nothing like you are doing. The diagram shows California Corners, which are designed for maximum insulation. While your corners are probably strong enough, how will you insulate them?
There really isn't a lot of options for framing. There is code, and then there are things that people do that are not Code. I'm guessing that you do not have Code where you live or any form of permitting and inspections. I don't have Code here either. I'm actually all for being able to do what you want on your land, and build any way that you want. My concern is that you are pushing your YouTube channel here on multiple forums to increase exposure and promote what you are doing, and people should know that you are not building to Code.
So far, I think you are borderline. Some things look good, some things are questionable. Your video does not show the things that you said you did after the video. Will that be in the next video? Do you tell your viewers that you are building according to the link that you provided and that it is designed to use "less" material to save money on framing?
