I am in the process of making part of a bunk in our bunkhouse a clothes hamper.
The bottom bunk always stays folded up like shown in the picture below. I got to wondering what it looks like under the wooden piece that it normally sits on when down.
I took some screws out and low and behold it is a bunch of unused space:
The stuff that you see on the left is the drawers for the outside kitchen. To the right of them there is a good amount of space not getting used. I have taken thatn 1/8" sheet of board that was covering and split it just about in half. I will screw the left section back on like before and will add a piano hinge to the piece on the right so it can be flipped up. I will also likely add a divider in there just to split the 2 sections up and make sure nothing can work its way over by the drawers and cause problems.
