Hello, I'm doing some remodeling project inside my house and I need to raise several non-bearing partition wall to form a study room.
The black is existing wall and blues are new ones. I got several books about framing but none of them talks about how to frame those 2 45-degree angles. Any ideas how to do that? Plus how to do drywall afterwards?
Thanks a lot for helps!
