Rob and I decided to rebuild the entire rear wall due to the extent of water damage.  Doing it in thirds seemed like a reasonable plan so as not to risk a collapse of the roof we had just completed.

The middle third was framed out yesterday, and plywood sheathing installed. Concrete was poured on the last third( to the right and up to the corner).

Next week we should be able to finish framing and plywood, then windows go in and siding goes up.
