Have you seen those plastic storage boxes, that you can leave outside in your backyard? Well the Wife wanted one and I thought to myself, “I can make one of those”. So that is what I did, a box with a lid. Sounds simple, but the tricky part is, it needs to be waterproof.
I came up with a design that I think will be waterproof. Made a simple box frame out of 2×3’s. Then wrapped the box in roofing paper to make it waterproof. I used my abundant supply of plywood strips and over lapped them, pin nailing and gluing them down with silicone.
I used the same design for the lid, but instead of the plywood strips, I used cedar fence boards. I made sure to use plenty of silicone because the lid will see the most rain. After it was put together, I then applied a good coat of deck waterproofer.
