My daughter's bedroom was getting a bit cramped so wanted to make a loft bed for her but I also wanted to incorporate a desk and some shelves for her books and toys. I started with the base plans from Camp Loft Bed with Stair, Junior Height posted on this site and kind of incorporated my own touch with the stairs, desk, book case. I also added a removable tray for when my daughter is eating a snack in her bed. It hooks on the top rail of the bed. Another addition I made was the wall shelf I mounted above the bed for storing her books, I-pad, etc.
Sorry but I do not have any plans for these modifications. I just made some simple drawings and winged it. This is my first ever build so hope you enjoy it
