Thank you in advance. I have been struggling with this problem for over a year. Every so often I try again to fix it and then give up. But I can't make any interior changes to this room until I get it right. I came here I think or another forum and got some help but I was never able to get the suggestions to work and I failed to save the suggestions so I need to start over.
The pictures should show the problem. Something I have done with the walls of the room over the garage is making the roof way too high. I've included the 3D of the inside and a photo of what the inside really looks like.
It's been a while since I tried working on this, and I know it's something to do with knee walls but I've read over the article about knee walls and I still don't get it. I'm happy to pay someone to just fix this for me, I don't need anyone to spend lots of time trying to explain it to me because you will no doubt get frustrated with my inability to understand. But If you think I can fix it, I'd love to get some help.
