Next up was repairing the framing that had been rotted away. We started with cutting back a few inches of the rotted existing ends of the floor joists that were running perpendicular to the back wall. Next, we cut 2 x 8's into approximate 3 feet lengths to serve as a new end to each floor joist.

After, new horizontal blocking was added between each joist:

Finally we could now add new support beams. We decided to go with 4 x 4s instead of the 2 x 4s that are standard issue for this type framing for added strength.

Once the supporting 4 x 4s were in the moment of truth arrived. We slowly released the jacks and let the flooring settle on its new bones. The scary part of this is having to be underneath the house while the load is transferred from the jacks to the new construction.
Last but not least for the day was installation of the 1/2-in CDX plywood shear panels over the new construction framing. In a few weeks I will remove the upper old sheathing and run new sheathing to meet with the bottom.

| Changed the location of the subfloor access door. It'll be more convenient here! |
Next step is going to be doing the same to the shorter wall next to it that contains a very old 6-foot aluminum sliding door. I don't think the door is going to survive so we'll be replacing it with a new vinyl one.
