Getting in on the Ground Floor

After removing the old floor, the next step was laying down plywood over the existing sub floor.

The existing sub floor was very thin, and ran on a diagonal.  Because we plan to eventually put room in the attic, we really needed this new sub floor to give the house diaphragm strength.

The existing sub floor was wavy and laying the plywood took longer than expected.  It reminded me when we did the shear walls.

I really never expected to have this much plywood in my house.
