A few 4x4 posts were sunk in concrete to form the south (front) wall. They were capped with a spanning 4x4, on top of which some long 2x4 rafters were laid across to the rafters of the coop roof.
Our spec called for serious anti-predation measures, so the top, bottom, and sides are all covered with "hardware cloth" -- essentially a more highly evolved form of chicken wire which uses something like 10 gauge wire to for 1/2" meshing.

And as a final touch, one more anti-predation measure:
Still needs some days of trim work and painting, but it's fully functional and in production use at this point. And the gals will soon be old enough to start laying, so we'll also have to get to building the nesting box to go inside the coop.
