How to create barrel vault dormer in roof

[Disharoon]

Hello all,

I am trying to create a barrel vault roof dormer. I've attached the file here. I have created a hole in the roof, and placed the window in a wall which I made invisible because when I left the wall visible, I could not curve the top of the wall leading to it sticking out of the top of the roof. I made the dormer room from two curved roofs joined in the middle. Now, the inside of this dormer is not correct. The structure is exposed. I created a polyline object to try to cover up some of the exposed roofing structure, but this has limitations due to the slope of the roof. There must be a better way to do this and I would love to get everyone's thoughts.
