Yesterday my oldest boy had a cross country meet out of state. But today we were able to build some.
I had my youngest son help in the morning and his older brother help in the afternoon. Then it took all three of us to stand up the wall. It is 16" on center and the wall is 9' high.
Completely built with reclaimed lumber. I am outsulating ( insulation on the out side of the wall ) so 2 x 4 are fine for the wall studs.
We built a work space out of pallets.
