Tiny Pallet House
Step 5: Building the Walls and Roof
Before adding siding or insulation be sure to bolt the pallets together. The stronger the connection between pallets the stronger your house will be. I would not trust nails or screws alone. I would use some bolts as the final connector. Also be sure your walls are strong before lifting the roof pieces into place.
Another step you might want to take (not illustrated) before raising the roof sections is to add a top plate on top of the walls to tie all the pallets together. This is usually done with long 2x4s.
