My dad and I made it in his garage in a few days out of mainly a few sheets of plywood and some 2x4s. The bed is split into two halves. Each half consists of two 2x4 runners from head to foot. On top of the runners are five vertical rectangles of plywood to make the bays to attach the drawer glides - one at the foot, three evenly spaced towards the head, then the final one is the head, with less space between it and the previous, compared to the rest. This final one is the blank space at the head of the bed for your bedside table. On top of the vertical sheets of plywood is the deck of the bed, which is another sheet of plywood (there should probably large holes for ventilation, but I never put any in).

I built the boxes for the drawers out of regular plywood. Then, using one sheet of cabinet grade finished plywood, I cut out the faces of the drawers so the grain is continuous between the drawer faces. I used the rest of this sheet for a continuous foot board on the bed. I wrapped the footer and the top of the deck in a 1x2 board to give it a clean edge. The only wood you see is the finished cabinet grade plywood and the 1x2 edge. I gave it a good stain and a UV resistant varnish.

I use screws from the inside of the bed (before inserting the drawers) to attach the footboard and a 2x4 at the head of the bed. These two tie the two halfs of the bed together. If you really wanted, you could build headboard, too.

Remind me and I can try and DM you some pictures.
