Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!
Assemble the bottom step by attaching the sides to the base with pocket screws and glue, then attaching the front in the same manner.
Assemble the middle step by attaching the sides to the bottom with pocket screws, then attach the front, followed by the base.
Storage stairs for a loft or bunk bed with :
2 deep compartments which can store toys or extra bed linens
a shallow compartment in the top step that is perfect for treasures or those large flat books
a small shelf under the middle stair that fits a rolled up sleeping bag perfectly
a large cubby under the top step that can be used as a crawl through, suitcase storage, could be divided into smaller cubbies, or could have doors attached.
Begin assembly of the top step by attaching the sides of the top step to the top compartment base with pocket holes and glue.
Attach front and back of top step from the inside with pocket screws and glue.
Attach top step base from underneath with pocket screws. (although the top step base is shown in the same color it is NOT the same size as the top shelf compartment base.
Join the bottom and middle steps to one another with pocket screws and glue. The join the middle and top step in a similar fashion. I chose not to glue the top step to the middle step so I could take them apart to move them.
Add 1 x 3 tread braces to each step. Again, I used pocket holes screwed from the inside. It would be easier to just screw down from the top.
Attach the stair treads to each stair with hinges.
