That seems to be nothing special, but immediately to the head idea to make a bench with a drawer and will not come. Meanwhile, a very convenient thing. If you put a bench near the playground, you need to constantly carry toys into the house and back.
However, the street box is a multifunctional thing. In the sense that there are always things that are constantly needed in the yard. In theory, you can fold garden tools, depending on where this bench will be. It's like a useful pot of Winnie the Pooh, you can fold anything. It would be nice to make another bottom pan so that the earth and sand do not accumulate, otherwise it will be hard to get.
