I am working on a 10' x 12' building with a 6' porch (16' x 12' overall). Roof is a simple gable that will cover the porch.
The porch roof will rest on 2x beams, which are supported by posts at one end, and by the building at the other end. I'm trying to figure out the detail of how to frame the wall to support the beams.
My plan right now is to shorten the last stud on the front wall, to act as a jack stud under the beam. Then I have a king stud next to it. Then a 3rd stud, to act as a nailing surface for drywall on the inside. (This is a full-length wall.)
The shorter side wall's 2nd top plate will be notched to fit around the porch beam. This weakens the joint between walls, so I may add a metal plate, as seen in Advanced Framing.
Front wall framing plan:
Is this a good approach?
I've considered extending the porch beam in to the side walls, perhaps to the next stud, but that would complicate things a great deal.
EDIT: Design snow load is 25psf here. With a 1' overhang, the total load on the beam is 1500lbs. Roofing is metal, slope 4:12.
