The IKEA Billy Bookcase Hack That Maximizes Storage In Any Bedroom

The built-in storage unit is a coveted feature in any home. But if your house doesn't already come with the storage already constructed, there's a way to make it happen with several Billy bookcases from IKEA, some paint, and also some patience. We won't lie — this hack from @mishkashoe on Instagram is on the more time intensive side of the DIY spectrum. But if you have the time, can assemble IKEA furniture and handle some painting, you'll have a beautiful storage solution soon enough.

The main thing about this project that makes it perfect for those looking to maximize storage, is the use of the BILLY bookcase height extension units. The addition of these pieces gives this storage hack its dramatic floor-to-ceiling height. And not only do the extensions make the whole unit visually stunning, but they are ideal for creating as much storage as possible.

Another special feature of this project is the combination of both open bookcases and closed ones. Using the OXBERG doors, which are specially built to fit onto the BILLY bookcases, you are able to create closed storage — perfect for those items you want to tuck away. And with the oak finished BILLY bookcases left open, you leave room for items worth displaying, like travel mementos and books. The alternating white and wood bookcases create nice contrast. And if you create the arch detail like the original DIYer, you'll add a chic, modern touch to your space.

First, you need to start by measuring your available wall space and determining how many BILLY units you need. Even if your walls do not fit exactly as many BILLY bookcases as the original DIY, you can easily customize this configuration however you need to. Just opt for more or fewer bookcases, and don't worry about following the alternating pattern perfectly.  For the OXBERG doors that cover the main part of the BILLY bookcase, you can avoid having to glue MDF and paint it solid by just purchasing the white OXBERG doors without glass. 

However, if you're opting for an extra thrifty way to complete this DIY, you may look for your pieces in the IKEA unboxed section. If you find the frame of a BILLY but it's not the right color, or it has a glass panel, then you may want to paint. The ultimate trick to painting IKEA furniture's tricky surfaces is to use a shellac-based primer. So, if you find yourself painting an entire door, don't skip this step. Assuming you need to use the BILLY extension pieces to make your unit go to the ceiling, and you want them to be closed shelves, your only option for a door from IKEA is the single version of the OXBERG glass door. If you prefer the doors not to be transparent, then you will need to cut MDF, glue it behind the door, paint it, and then install the door facing forward.

The final step to this DIY is the arch design that spans across the two OXBERG doors. Using a string, anchored in between the doors and attached to a pencil, you can use the tension to draw the arch smoothly. Then, just use that line to place trim like this Art3dwallpanels peel-and-stick half-round molding, which costs just $8 per roll. If the arch design doesn't suit your style, then this is where you can get creative and make the DIY completely your own. If you like the idea of molding, but prefer a more traditional look, try TikTok's brilliant box molding DIY instead.

Another way to customize the look of your new BILLY unit is to use a different paint color on the door. If you are painting beneath the arch, you can opt for a bolder color than the beige used in the Instagram video. You can also use peel-and-stick wallpaper if you want to implement a pattern. And of course, you can also give a bespoke look to your storage by picking unique hardware for the OXBERG doors. IKEA has plenty of types of cabinet hardware to choose from at reasonable price points. Or you can simply browse the web for an endless sea of options. Go for an oiled brass look like @mishkashoe, or opt for something entirely different like a bright pop of color.
