Brick stacker - GIF

[Toolmaker51]

No framing beside insignificant door jambs. The original roof (barely 2:12), supported by 15 6x6 nominal posts, the set-in rafters were retained in pockets formed by brick too.
Now, trussed roof sits on 2x12 plates bonded & anchored atop walls. One wall was a pediment for drainage on a zero lot line. That was lowered a few courses to lowest plane, still have 15'8" as before, but now free span.
Win. Win.
