Sketch out your design on paper or use a digital tool. Consider the height and width of your space. Will you need adjustable shelves? Do you want a simple, clean look or something more decorative? Your design should reflect your personal style and storage needs.

Once you've finalized your design, create a detailed cut list. This will ensure you have all the necessary pieces to build your bookcase.

Using your cut list as a guide, cut your plywood and lumber to size. Remember to wear safety gear when using power tools. If you're using a jigsaw or circular saw, consider using a guide to ensure straight cuts.

Don't forget to label your pieces as you cut them. This will make assembly much easier.

Assemble the Frame

Begin by assembling the frame of your bookcase. This will provide structure and support for the rest of your build.

Using your wood glue and screws, attach the side pieces to the top and bottom pieces. Ensure your frame is square by measuring diagonally from corner to corner. If the measurements are equal, your frame is square.

113K views · 3K reactions | I built this under-stair storage using IKEA Platsa units and turned them into pull-out storage by adding castor wheels (make sure they’re non-swivel so the units go in and out straight 🙌🏼). I then added plywood fronts, covered them with acoustic panels for that built-in slatted look, and finished with a small filler piece in the corner so it looks completely custom. Honestly one of the most satisfying DIYs I’ve done — and it’s completely removable if we ever need to change it!👌🏼 I’ll pop the exact dimensions of my units on Stories and save them in my highlights so you can screenshot for later 🤍 under stair storage, IKEA hack, Platsa hack, sliding storage, DIY built in, budget DIY, family home storage, hallway makeover #ikeahack #ikeaplatsa #understairstorage #diyhome #hallwaystorage | Pamela Latte & Lullabies | Facebook

Attach the Back Panel

Next, attach the back panel to your frame. This will provide support for your shelves and prevent your bookcase from warping.

Apply wood glue to the back of your frame and attach the back panel using screws or nails. Ensure the panel is flush with the frame.

Install the Shelves

Now it's time to install your shelves. If you're using adjustable shelves, install the shelf pins first. Then, place your shelves on the pins and adjust as needed.

If you're using fixed shelves, measure and mark where you want them to go. Apply wood glue to the shelf and the back panel, then attach the shelf using screws or nails. Ensure the shelf is level and flush with the front of the frame.

Finishing Touches

With the structure of your bookcase complete, it's time for the finishing touches.

First, sand any rough edges. Then, apply your paint or stain. If you're painting, consider using a primer first to ensure even coverage. Allow the paint or stain to dry completely between coats.

Install Your Bookcase

Once your bookcase is completely dry, it's time to install it under your stairs. If your bookcase is heavy, you may need help moving it into place.

Use shims if necessary to ensure your bookcase is level. Then, secure it to the wall using brackets or screws. This will prevent it from tipping over.

Step back and admire your handiwork. Your under-stair bookcase not only adds storage but also adds charm to your home. Happy reading!
