Normally I don't care for lids on toy boxes for little kids, for several reasons. But, the idea of two lids is neat. For little kids, you can just leave them open all the time, and they can get toys out, or dunk them back in easily.
I would not use metal corner braces as shown in the plan. You could use glue blocks, which would be better, or glue a strip the length of the join, which I prefer. I did one like that, with strips, maybe 6 years ago, and it's still holding up great - Titebond II, and just a few brads to hold everything aligned, until the glue set. The only thing I wish I handn't done, was paint the sides dark blue. I feel I probably had more colors than just that on hand, so I have no idea why dark blue. I'd repaint it, but the grand-dau won't give it up.
