cyma recta?? please enlighten me?
The plates/purlins/ridge will be as long as possible to support roof overhang. The lower plates will be cut back to the inside of the wall. I'm still not sure about this frame, it's sort of like platform framing at this point.
yes, the stairs are as you wrote.
At this point we are looking at roof panels, hopefully without rafters, and possibly wall panels.
Thank you for sharing.

Hi Mark, So does the ridge extend from interior to exterior? I am interested in how you would do this. How do you not sacrifice the envelope in that situation. If you could do this and have the horizontals exposed to the outside you could


one way or another.

yes, the ridge and purlins and top plates will have to be out in the elements. I think expanding foam does an ok job of sealing the timbers to the wall. what are your concerns around this?
I like the "Cavetto"
