I'm back with an updated design and would love some feedback. I have finally found a good source of trees for timbers and will start on this project as soon as I can get there to cut and limb the trees and get a sawyer in to mill the beams (poplar and ash).
The intended location of the shop has changed and I am back to having it facing due south. As such, I wanted some bit of the roof facing south for the potential to accommodate solar panels in the future. I also realize that with the footprint (12'x16'), I need to include a storage loft. I came up with this design allowing for transom windows with 4/12 roof pitches front and rear.
What I don't know is if the support for the mid-wall on the loft level where the transoms would be is acceptable over the tie beams in the bents. All beams shown are 6x6 nominal. Rafters are 3x10. The loft is only over the rear half under the higher roof. Not sure how to deal with supporting the end rafters at the upper end of the lower roof, so I would be interested in strategies there.
