There's a nice set of plans and instructional videos on this site for a red cedar storage box. It looks great and I was excited to build it...that is until I realized that its very design is flawed. I need something in which I can store lawn furniture and other misc. items, so it needs to be waterproof. I supposed I could modify the lid so that it is more water resistant, but if anyone has plans for a waterproof (or at least resistant) deck box, I'd really appreciate it.
