Best IKEA Billy Hacks
1 — Classic Crown Moulding
Attach crown molding to your freestanding bookcases. This inexpensive upgrade can dramatically change the look of your furniture.

She includes step-by-step instructions and photos of building a base, securing and framing the units, adding molding, and finishing with paint to achieve a high-end built-in look on a budget.
2 — Custom Arch
Add arches to an IKEA Billy bookshelf by attaching thin MDF or plywood cut into arch shapes to the front of each shelf opening.
For extra European-esque vibes, A Carried Affair accented her arches with rose appliqués. The Ikea hack tutorial also features added doors on the bottom for hidden storage.
3 — Entertainment Center
Transform your Billy shelves into a stylish entertainment center. Use closed cabinets to hide cords and open shelves for your media devices, creating a functional and attractive setup.
This Billy bookcase hack built in with TV uses multiple bookcases to create a custom entertainment wall. Custom built-ins can typically cost over $2,000 whereas this DIY project only costs under $600!
4 — Fluted Cabinet Doors
Enhance your cabinet doors by using chair rail molding. This simple addition can give your bookcase a sophisticated touch.
We’ve seen many Ikea Billy hacks with doors, but this project takes it up a notch by creating a fluted look with pole wrap trim. Leather pulls adorn the European-inspired arched cabinet. The final results of the crafted arched tops and fluted textures feels high-end and tailored rather than flat-packed.
5 — Custom Paint
Use bold paint to make your bookcase a standout feature in the room. A vibrant color can add character and brighten up your space. A dark color brings drama, luxury and warmth.
This arched IKEA Billy built-in tutorial leans hard into color to make the shelves look custom. Painting IKEA furniture can look amazing if you prep the laminate right. It’s also all about patience. Paint may feel dry in hours but allowing it to cure for a few days is ideal.
6 — Glass Doors
Add glass doors to your dining room display. This allows you to showcase your favorite dishes while keeping them dust-free.

Transform a Billy bookcase into a dollhouse for kids. Use wood to divide the shelves and create fun, imaginative play spaces.
Adding an angled, shingled roof completely transforms this IKEA Billy dollhouse hack into a house-like statement piece, perfect for a little girl’s bedroom. By modifying the top of the bookcase to create a pitched ceiling and finishing it with shingle-style details, the project adds dimension and architectural charm to the classic Billy shape.
9 — Wallpaper Backing
Use removable wallpaper to add personality to your bookcase. Combine it with decorative molding for a unique flair.
Instead of paint or trim, this Billy IKEA hack uses wallpaper to completely transform a basic bookcase into a standout focal point. By wallpapering just the back of the shelves, the project creates high visual impact with minimal commitment, proving how powerful this simple upgrade can be.
10 — Workstation Storage
Use two back-to-back bookcases to create an office storage solution. This setup can help organize your workspace effectively.
This office makeover uses a smart mix of IKEA Billy bookcases to create a custom, built-in look while maximizing every inch of space. By alternating full-size and half-size Billys, the shelving fits seamlessly around a desk and bench without extra modifications. Bead board between the shelves adds texture and cohesion, while stopping the bookcases short of the ceiling keeps the room feeling taller, lighter, and less crowded.
11 — Library Ladder
Add a ladder for both functionality and style. It not only looks great but makes accessing those high shelves a breeze!
Creating a home library with IKEA Billy bookcases is all about smart planning and a little drama (in the best way). Line multiple Billys along one wall for a seamless library look. Then, install a rolling library ladder by securing a metal rail into wall studs or a header board above the shelves for proper support. Keeping the bookcases level, evenly spaced, and anchored together helps the ladder glide smoothly.
12 — Pantry Shelving
Utilize a Billy bookcase for pantry organization. Adjust the shelves to accommodate tall items and use bins for easy access to food and supplies.
When custom pantry shelving proved too expensive due to rising lumber costs, this makeover turned to IKEA Billy bookcases as a budget-friendly alternative. The shelves provide sturdy, adjustable storage that can be easily customized to fit pantry essentials. Anchoring the units securely, spacing them thoughtfully, and adding trim or paint can help the bookcases feel intentional and built-in rather than purely utilitarian.
13 — Playroom Storage
Stuff all the playroom toys in Billy bookcase behind glass doors and pull the curtains when you want them hidden. This not only looks fun but also keeps toys organized and accessible.
This clever IKEA Billy hack transforms 2 bookcases with glass-paneled doors into a charming cabinet that blends storage with softness. After priming and painting the doors (before attaching them for easier coverage), add pleated fabric panels behind the glass to conceal toys and books while adding pattern and warmth. No sewing required, and perfect for any playroom!
14 — Kids’ Room Closet Storage
Repurpose the Billy bookcase using the shelves for folded clothes, bins, and shoes, while leaving lower sections easy for little hands to reach. Add baskets, labeled bins, or even a hanging rod to create a flexible system that grows with your child.
Because the Billy bookcase features adjustable shelves, this budget-friendly $150 project is flexible enough to grow with the child. Modify the shelves to accommodate hanging rods, folded clothes, and storage bins to create a functional layout tailored for your child’s essentials. It can work in a baby room or a big kid’s room.
15 — Reading Nook
Frame a window seat with tall bookcases to create a cozy reading nook. This setup invites relaxation and makes your space feel more inviting.
Carving out a cozy corner, this IKEA Billy hack turns simple bookcases into a built-in daybed and reading nook. The shelves are arranged to frame a bench seat, maximizing vertical storage while creating an inviting spot to lounge with a book. With added trim and cushions, the finished space feels custom and architectural rather than modular.
16 — Textured Cane Doors
Upgrade your bookcase with woven cane doors and a coat of paint. This combination creates an expensive look while using affordable materials.
Even though IKEA now offers Billy bookcases with cane doors, the design options are pretty limited and basic. You can easily hack your own for a more custom look. Or modify the IKEA option to feel more cohesive. Painting or staining the doors beforehand helps the natural cane texture stand out, whether you’re going for a coastal, boho, or mid-century vibe. For a polished finish, add upgraded hardware and be sure to seal the cane lightly to prevent fraying over time. Cane decor is here to stay!
17 — Shared Bedroom
Turn the bookcase into a functional room divider to create distinct zones in a bedroom while adding extra storage.
This whimsical woodland project uses the IKEA Billy bookcase to help define a shared children’s bedroom.

18 — Billy Bookcase Horizontal Hack
Lay an IKEA Billy bookcase horizontally to create a low-profile storage piece that doubles as a bench, console, or room divider. Positioned along a wall or at the foot of a bed, it offers accessible storage while keeping the space feeling open and airy.
