Foundation and floor
4 pressure-treated 4x6 skids run front to back on a compacted gravel pad. The floor joists run across them, so no joist spans more than 46-13/16". See the foundation guide for leveling and squaring.
Wall framing
Walls are drawn from the outside. The side walls run the full depth and carry the rafters; the front and back gable walls fit between them. The wall framing guide walks through layout and raising.
