If you've ever walked past an old IKEA bookshelf and thought, "What else could this be?", you're not alone. At Reperch, we believe in extending the life of your furniture through smart, stylish reinvention. IKEA's iconic Billy bookcase, in particular, offers a blank canvas that’s perfect for transformation. Whether you’re short on space or simply want custom storage without the designer price tag, repurposing your bookshelf can bring big results on a budget.

In this guide, we’ll explore the best IKEA bookshelf hacks, with tips, real-life examples, and pro insights to help you reimagine your furniture like a seasoned DIYer.

Why Hack an IKEA Bookshelf?

IKEA furniture is famously affordable, accessible, and modular. But with a little creativity, it can also become one-of-a-kind. The Billy bookshelf is a fan favorite for several reasons:

• Customizable sizes: Available in narrow, tall, and wide formats.

• Flat surfaces: Easy to paint, trim, or modify.

• Timeless design: A clean, minimal silhouette that blends in anywhere.

• Sustainable choice: Repurposing means fewer items in landfills and more unique furniture in your home.

Whether you want to save money, create something beautiful, or reduce waste, hacking your bookshelf is a satisfying solution.

Hack #1: Built-In Bookcase Library

Project Inspiration: Caroline McQuistin (@carolinemcquistin on TikTok) created a built-in library from three Billy bookcases, saving thousands on custom carpentry.

What You Need:

• 3 or more Billy bookcases

• MDF boards and trim

• Wood glue, brackets, and paint

Steps:

1. Arrange bookcases flush along a wall.

2. Attach trim to blend the gaps and create a custom look.

3. Paint everything to match your walls for a seamless finish.

Pro Tip: Anchor the units to the wall for safety and a professional look.

Hack #2: Turn It Into a Window Bench

Project Inspiration: One DIYer needed low shelving that wouldn't block their window and reimagined the Billy horizontally.

What You Need:

• 1 Billy bookcase

• Corner braces and screws

• Chalk paint and felt pads

Steps:

1. Cut the sides to reduce the height.

2. Use corner braces to stabilize the new base.

3. Paint and pad the edges for a clean, soft-touch finish.

Bonus: Add a cushion or two on top, and now you have hidden storage and extra seating.

Hack #3: Create a Built-In Desk Space

Project Inspiration: @fromcatterytohome used Billys on top of a desk to create a full-height office setup that blends into the wall.

What You Need:

• Multiple Billy bookcases

• A butcherblock or IKEA desk

• Matching paint

Steps:

1. Flank the desk with tall bookcases.

2. Paint everything in the same color.

3. Add trim and baseboards to integrate the unit.

Why It Works: You get vertical storage, a workspace, and a designer look in one go all without the bespoke cost.

Hack #4: Bedroom Dresser Built-In

Project Inspiration: HomeonHarbor created a chic dressing nook using two 15-inch Billys and a 30-inch center unit.

Key Features:

• DIY drawers built into shallow Billy units

• Crown molding and baseboards for a custom feel

• Doors for hidden storage

Tip: Billy bookcases are only 11 inches deep, making them perfect for tight spaces like hallways or closet entrances.

Hack #5: IKEA Billy Arched Cabinet

Project Inspiration: Inspired by Pinterest, HomeonHarbor used Billys and MDF to create an arched cabinet with hidden storage.

What Stands Out:

• Arched cutout made using a jigsaw

• Painted in Alabaster by Sherwin Williams for a high-end touch

• Doors conceal toys, power boxes, and electronics

Why It Matters: This project turns a basic bookshelf into a showpiece while maintaining its original function.

Hack #6: Surround Your Sofa with Storage

Project Inspiration: @onemoreproject built wraparound shelving using various Billy sizes to frame their sofa.

Process:

1. Stack and anchor multiple bookcases like Tetris pieces.

2. Add crown molding for a polished look.

3. Paint the whole unit a bold tone like Yorktowne Green.

Pro Tip: Use OXBERG doors on bottom shelves for concealed storage and visual balance.

Hack #7: Hide Electronics Behind Closed Doors

Why It Works: Billy bookcases with glass or solid doors (OXBERG) make ideal media cabinets.

How to Use It:

• Cut out cord holes for TVs or consoles

• Add trim to elevate the look

• Paint to match your room palette

This option blends form and function plus, it’s renter-friendly.

Hack #8: Built-In Wardrobe Using Billy Bookcases

Project Inspiration: DIY Doctor Soph and other creators used Billys to build affordable wardrobes.

Modifications:

• Use extra trim for flush edges

• Paint to match the room

• Add stylish hardware or brass feet for a luxe look

Warning: Billys don’t support heavy hanging storage, but they’re great for shelves, shoes, and bags.

Hack #9: Add Drawers, Doors & Cane Accents

Get Creative: Add visual interest by installing rattan doors or painting patterns. Use the Billy frame and customize fronts for a boutique feel.

Affordable Updates:

• Add cane webbing

• Use high-end hardware

• Paint in trendy finishes like matte black or muted green

Final Tips for a Successful Hack

• Always anchor tall units to the wall for safety.

• Prime first: IKEA laminate needs a shellac primer like BIN to prevent peeling.

• Use trim and paint for a built-in effect.

• Don’t rush: Measure twice, cut once.
