One and a half story roof

[BlueBSH]

Are you looking for something similar to what is shown in the image below?

The upper shed roof section was created using a floating dormer with the roof type set to "shed roof".

Let us know if you need more detail or if you can carry forward on your own.

yes similar to that, I actually had the shed roof dormer idea, but inside I saw a sloped roof where the dormer went below the ceiling height... anyway to prevent that? also the gabel end of the roof inside you could see, and I need to build I guess they'd be knee walls? to section that part off inside so it looks like the shead roof part is just a square normal room inside
