This stage of the build makes a big visual and structural change to the tiny house. Not only does the appearance become more solid as the framing is covered, but the entire structure becomes completely rigid. No longer does the 2×4 framing creak when moving around in the lofts.
The plywood goes up fairly quickly depending on the details of the cuts. In most cases my Dad and I were able to get two sheets of plywood up each evening after work. This really helped to speed along the building process by chipping away at it daily instead of waiting for the weekend.
I chose to use 5/8″ 5-ply plywood for everything including subfloor, roof and walls. The extra weight was acceptable on my upgraded trailer. The extra cost was less than $3 per sheet compared to the 1/2″ plywood. The quality was significantly better than the selection of 1/2″ plywood. And finally, the added strength was worth the added weight and cost.
Each sheet of plywood is glued and fastened with 2-1/4″ galvanized ring-shank nails.
I used blue painters tape to mark the positions of the studs, then chalk lines once the plywood was in place. This made nailing into the framing much easier.
I created a simple cardboard template which helped with this step.
Luckily, no one was hurt. The ladder was a little bent out of shape, but still usable.
I now have a finely crafted, labor intensive plywood box on wheels.
Next on the to-do list: roofing.
