19 IKEA Billy Bookcase hacks and ideas for your home

Over the years, IKEA Billy bookcase hacks have become more imaginative, sophisticated, and stylish much like the IKEA Besta hacks and IKEA Kallax hacks. Consequently, this flatpack staple could solve all your home-storage woes. 

1. Perfect kitchen pantry with plenty of storage

This pantry storage hack is so good you’d be forgiven for doubting it was a budget-friendly build to make a kitchen look expensive. Six Billy bookcases, two tall units for the sides, and four small central units, all with Oxberg doors, provide a wall of built-in organised pantry storage and two height extension units with glass doors make full use of the tall ceilings for maximum concealed storage.

Rachael Fuller, an interior designer at Full Home Design, had an empty kitchen wall that was crying out for extra storage but she didn’t fancy paying thousands on brand new cabinetry, so she came up with a creative plan which turned out to be one of the best DIY pantry IKEA Billy Bookcase hacks we’ve seen. 

The stylish design encompasses a central area complete with brick wall detailing, handy shelving, and a countertop area; stylish brass knobs elevate the finish of the doors, and crown moulding and baseboards complete the built-in look.

2. Dining room built-ins with vintage ladder

This dreamy green wall of dining room built-ins screams ‘Bookshelf Wealth’ trend as it boasts a beautiful collection of stylishly displayed books and home accessories. You might be surprised to hear that it’s an IKEA BILLY bookcase hack, as it looks so bespoke. 

Donna Wardell aka @welcome_to_no.1 had this wall of built-in shelves created using BILLY bookcases of varying width joined together with moulding installed over the joins to create a seamless look. 

After filling, priming and painting, the addition of the vintage-style library ladder and some handpicked accessories finished the look. Donna added a wallpaper border above the units, and some statement lighting to the room, and the results are superb. 

3. An affordable appliance pantry

Over the years, it’s easy to acquire a sizeable collection of kitchen appliances. A milk frother here and a best blender there and before you know it, your kitchen cupboards are heaving with handy gadgets and kitchen essentials. The answer to this modern-day problem is an appliance pantry, a dedicated storage area to keep up with small kitchen appliance trends. 

Self-taught DIY aficionado Jennifer Amarteifio @frontlinediy designed the perfect DIY project to enhance her existing pantry with a bespoke-looking Billy bookcase hack to store her kitchen appliances. 

This Billy bookcase hack is simple and effective and requires little in the way of additional tools and materials. "All I did was add 1x2 primed trim to the face using my Brad nailer. I also added a piece of baseboard to the bottom for that built-in look," Jennifer explains. "I adjusted the shelves to the heights I needed for my appliances. Then I filled all the shelf pin holes with spackle and wiped with a baby wipe."  

The great news for novice DIYers is that this hack can be replicated without hours of arduous painting or changing your existing kitchen paint color. Jennifer only painted the trim rather than the whole bookcase, matching the white to the shade already in her beautiful pantry. This super hack proves that sometimes simplicity really is best. 

4. Stylish arched cabinet with storage and shelves

This project is one of those Billy bookcase hacks where you have to do a double-take because it looks so high-end – the perfect way to make a living room look expensive on a budget. 

Callie and her husband Robert, founders of the transformation blog Home on Harbor, are talented DIYers with a keen eye for design and an impressive array of IKEA hacks under their belt including this awesome arched cabinet. 

Callie, who shares her renovation work on Instagram @homeonharbor, explains why the Billy bookcase is one of her favourites, "They're so versatile and a great size to fit into even small spaces. We used two 30-inch wide Billy bookshelves with 4 Oxberg doors for this project."  

The arched detailing at the top of the Billy bookcases is inspired and that’s not the only feature that cries bespoke. Formed from two standard Billy bookcases joined together and accessorised with trim woodwork, baseboards, and crown moulding, it isn’t the most complicated of hacks, but the attention to detail and the high-quality finish make the finished article sing. 

Callie has this clever tip for would-be hackers, "We painted it the same colour as our walls to give it a true built-in feel. Painting IKEA furniture isn't hard; you need to make sure you follow the right steps.  Lightly sand the pieces, prime them with a good primer (I like Kilz), and then use two coats of high-quality paint."

This bespoke-looking cabinet would be perfect in a dining room where the cabinet could be used for storing dinner-party crockery and cutlery. The open shelves are perfect for styling with your favourite ornaments and home accessories. 

5. A beautifully bespoke home library

The next DIY project in our round-up of the best IKEA BILLY bookcase hacks is this jaw-dropping navy blue beauty from Sanda Stojakovic aka @design.playbook, the owner and lead designer at Stojakovic Designs. 

Sanda transformed her formal living room into a library room boasting a wall of IKEA built-ins, a soft peach ceiling, a stunning chandelier, and stylish sconces. The results are so professional and expensive-looking that there’s no hint of a Billy bookcase hack on first inspection, but they are under there, trimmed, filled, and painted. The thoughtful ceiling paint colour is another stylish touch to exude an interior design aesthetic.

Similar to a chic IKEA closet hack Sanda has created a bespoke finish by filling the gaps between the bookcases and the walls and ceiling and adding baseboards and crown mouldings to create a built-in look and the results are a triumph. 

6. An extra-wide media console

Dalia E. Aly is an architectural designer, although, after seeing this incredible IKEA Billy bookcase hack, you might suggest she should add a magician to her CV. 

This clever DIY project looks more like an inspirational IKEA IVAR hack but in fact, it turns Billy bookcases end-to-end on their side to create a stunning media unit with a bunch of extra touches thrown in for good measure. Dalia needed an extra-wide unit and knew the tall BILLY bookcase would fit but wanted a high-end look, so she set about planning a creative custom makeover. 

After sketching out her vision, she started the DIY. Here, on TikTok, Dalia explains how she did it, “For the legs, I really wanted to have round, almost drum-like legs, so I attached two bowls together and drilled a hole through them the size of the legs I was going to attach - that way the legs would pass through the bowls to the ground and the bowls wouldn't bear any of the structural weight.” 

Next on the DIY list were the doors, “For the doors, I wanted them to have a textured, almost natural look, so I attached a linen canvas to IKEA's Oxberg doors. And finally, for the actual unit, I calculated where the shelves would go so that the doors could fit onto them and screwed them on from both ends,” another inspired idea. 

The results speak for themselves and Dalia is understandably proud of her work “I love every aspect of how it turned out, from the neutral tones and textures to the subtle drama. I'm especially proud of the legs, conceptualizing the shape and how I was going to DIY them, and figuring out a way to include them without having them bear any of the actual weight.” 

7. Luxe-look pull-out bar with glass shelving

Kirsty Griffiths is an experienced IKEA hacker with some seriously impressive hacks under her tool belt. This project is the first bar-related one on our list of amazing IKEA BILLY bookcase hacks and makes quite the impression. 

Kirsty used two IKEA LOMMARP bookcase units (for the movable bar) along with three BILLY bookcases (two 80cm and one 40cm wide) for the wall storage. She cleverly installed IKEA’s lesser-known UTRUSTA glass shelves to the BILLY units for a luxe look. 

She added a faux marble worktop over the top of the base units to create the high-end bar look and made the genius decision to add coaster wheels to the underneath, meaning she can wheel the bar unit back and forth. Attaching the BILLY bookcases at exactly the right height on the wall meant Kirsty could roll the bar in and out as needed.

Kirsty covered over any joins in the BILLYs and added a top section complete with decorative moulding for a bespoke look. The wallpaper behind the shelves adds some pattern and complements the shelf styling. Who could resist a stylish and unique bar in their living room? 

8. Cosy reading nook complete with shelves

Amy Bennett of Abigail Amira LLC used Billy bookcases to create an eye-catching reading nook in her beautiful home, complete with stylish built-ins. Amy used dark green paint, elegant gold picture lights, and intriguing objects to style her sophisticated built-in bookcases, another creative transformation in this selection of Billy bookcase hacks. 

Once again, the DIY aspects of this project were fairly straightforward but very effective. The Billy bookcases and height extension units were attached to the wall for security and made to look built-in. Amy explains how she did it," I used a 1x6 for the top header to cover the gap between the top of the shelf and the ceiling. It also created a nice place to add battery-operated picture lights!"

"I used three 1x3s for the vertical trim (one on each side of the bookcase and one in the centre). Finally, I added a 1x12 on the exposed side of the bookcase and then a small, flat trim piece to close any remaining gaps between the trim and ceiling."Once the construction was complete, Amy primed and painted in a stunning shade of forest green. 

Making a feature of your book collection is the perfect way to celebrate your collection after decluttering your books, not to mention a great bookshelf idea for a small room to maximise space.

9. Amazing mudroom area with storage and seating

A mudroom is on many people's list of dream home attributes, but fully bespoke furniture costs thousands and requires space that not every home can offer. 

Home stylist and content creator Jessica Nickerson came up with the perfect solution to this dilemma and no prizes for guessing which classic IKEA bookcase she used to create this clever hack.

Jessica’s mudroom hack, as shared on her blog househomemade, takes up surprisingly little space, but every inch is considered, offering storage, hanging space, and even seating, the perfect example of how to organise a small space. The mudroom consists of two fifteen-inch Billy bookcases with height extenders, connected by a central shelf and seated on an IKEA Besta TV cabinet for extra storage.  

This hack is a savvy way to create an entryway in a living room where you want to define a different purpose for the space.

10. Dreamy daybed with built-in storage

This daybed is pretty genius in the DIY stakes and certainly one of the best IKEA Billy bookcase hacks you’ll find. This hack comprises a plywood base that forms the bed component of this beautiful set-up, accompanied by four IKEA Billy bookcases, one wide and one narrow at both ends of the bed. 

This daybed hack isn’t just functional, it looks super stylish and would make a real feature in a child’s bedroom or guest room to organise a small bedroom. Using IKEA furniture and DIY keeps the project costs well below that of a bespoke build. 

Jessica Nickerson @househomemade is the clever content creator and home stylist responsible for this brilliant design and here are some of the tips she shared on her blog househomemade about this project. "We used the Billy bookcases from IKEA. I slid the bigger shelf onto the base and used the bracket hardware at the bottom and screwed it to the wall a few times near the top."

Jessica cleverly thought to fill and paint the pin holes to make the shelves look custom and also used trim to fill any gaps between and around the units. "They’re space-saving and custom-looking. The bed helps this room to double as a guest bedroom."

To replicate this hack you’ll need to measure the space you have and plan meticulously to ensure there is enough room to fit the daybed and storage. If you are pushed for space and don’t have a window to consider, you might decide to add the shelving at one end of the daybed or the other. 

11. Adapted set of drawers

Believe it or not, that is a Billy bookcase under there. This clever hack from the New Infarrantly Creative blog has transformed the usually recognisable bookcase into a unique and quirky drawer unit by adding two additional shelves and then making drawers to fit the shelves. 

This hack involves a fair amount of cutting and assembling to make the custom drawers, so you’ll need tools and some plywood to replicate it, but the final piece is worth the effort. You could prime and paint the whole thing in the same colour and attach matching handles for a unified look, or opt for a more eclectic style as the creator did here.

12. DIY luxury shelves with arched detailing

This Billy bookcase hack has several standout features, including the dreamy dark paint job, the attractive arches, and stylish storage, to name a few. This masterpiece is the work of talented DIY and home interior content creator Elisa Mastrocolla @theedgewoodhome. 

Elisa explains how this DIY hack came to be, "I had an empty wall in my living room and desperately needed some storage room but after doing some research and crunching some numbers, I knew a custom built-in wasn’t in the budget. Using IKEA furniture seemed like the perfect choice.  I chose the Billy/Oxberg option because it comes with doors and I knew I wanted cabinets and shelves."

Using IKEA furniture and customizing it kept the costs down so even a project of this large size came in under £680 ($850) Elisa confirms she "couldn’t be happier with the final product," and it’s not hard to see why.

Using a dark paint shade and continuing it along the adjacent wall creates a feature within the room and paired with a dark shade of flooring, gives an overall cosy and relaxing feel to this living room. Colour drenching in this way avoids making common mistakes when decorating with dark colours.

13. Transformed bespoke-looking bookcases

With trendy details like fluted doors and leather handles, this project looks extremely high-end, but you’ll be pleased to hear it’s affordable, achievable, and can be completed over a weekend. 

Designer, style expert, and writer Jennifer O’Brien @cityfarmhouse1 is the creative genius behind this stylish makeover, shared on her blog City Farmhouse. Jennifer bought three Billy Bookcases with doors from IKEA, which she primed and then painted. 

The next steps in the process are clever and hold the key to the final luxe look. Jennifer attached pole wrap to the lower doors with strong adhesive to give a stylish fluted texture, then templated and painted the upper doors to create an arched effect.

Reflecting on the project's success, Jennifer advises, "The best ideas come when you can’t afford something. I saw a set of arched cabinets but couldn’t justify the price. I got creative and found a way to get the look from much less using three IKEA Billy Bookcases. In the process, building on the skills I had." The results are an amazingly chic set of furniture and one of the most stylish Billy bookcase hacks around. 

14. Bespoke shoe closet hack

Too many shoes or insufficient storage space is a common complaint, resulting in shoeboxes stacked in every spare bit of closet or under-bed space. This can make finding the perfect pair of shoes time-consuming and tedious. The answer is stunningly simple, consult your big book of Billy bookcase hacks and DIY yourself a built-in, open IKEA shoe closet like Florida-based style blogger Shannon Jenkins @upbeatsoles.

This stylish hack uses two standard IKEA Billy bookcases with height extension units on a raised timber base. Shannon wanted a slick floor-to-ceiling look which she achieved by adding a plywood box to the top of the extended bookcase. Decorative trim was added to the top and bottom of the now built-in units to create a bespoke look. 

Shannon’s clever design created a central alcove, perfect for a huge mirror to check you’re looking your best before heading out in the perfect pair of shoes. Shannon advises, "Plan out the style trim you are going for first. Pick out all materials and paint colours. Then draw out a plan with all measurements."

The results speak for themself, a stylish and practical shoe closet that creates a feature from your organised shoe collection. 

15. Captivating shelving

Billy bookcase hacks are popular because, despite their many advantages, Billys lack style straight out of the box. Luckily for style-conscious DIYers, they are super easy to customize, as I demonstrated with this pastel-hued hack on my blog Claire Douglas Styling.

This IKEA hack wall of bespoke-looking built-ins was formed from four standard Billy bookcases, four Oxberg doors, many MDF strips, caulk, and some strong postal tubes.  The trick was to fill the gap between the top of the bookcases and the ceiling with an MDF-covered frame to give a bespoke look.

Cardboard postal tubes might not be a common DIY material, but they are an affordable and sustainable way of adding a tubular texture to surfaces – I love using them. I glued the tubes to the Oxberg doors, primed then painted them. They completely changed the project's look, adding an element of fun. The pastel colours transform the wall from drab to fab and make a small living room look bigger as they draw your eye around. 

Being bold with colour or texture in IKEA Billy bookcase hacks is a great way of making them stand out.

16. Create a bespoke freestanding arched unit

There are a few striking elements that make this next IKEA BILLY bookcase hack such a success. The detailed crown moulding, the beautiful arched top, the positioning of the shelves and the thoughtful styling, to name a few. Best of all was the affordable price tag of this amazing storage and display unit.

Here, Urska Oman, the creator of this masterpiece shares the actual costs, “The whole project cost around £345 (400€), I think that is truly a budget-friendly option for that kind of statement piece of furniture. I am always on the lookout for the next Ikea hack.” 

Urska joined three narrow IKEA BILLY bookcases, added OXBERG doors, thoughtfully arranged the shelves and added a bespoke arched piece to the top of the unit before attaching the detailed moulding around the very top. 

The attention to detail makes a big difference to the quality of the finish and it was worth the effort to fill every gap and shelf hole before applying the beautiful paint job. This project is ideal for those with champagne tastes but a lemonade budget, to get the minimaluxe quiet luxury look for less. 

17. Slick and stylish library wall

This next project is another scroll stopper, full of character and styled in a dark and dreamy hue. The designer and DIYer of this masterpiece is Aychul Schultz, who regularly shares inspiring home renovation and styling tips on her Instagram account @inthehouseofdavid. 

Believe it or not, five IKEA BILLY bookcases with height extenders are at the heart of these beautiful built-ins. We asked Aychul about this transformation and she was kind enough to share some of the secrets to her success. 

“We are very drawn to vintage dark academia design, so we added lots of moulding. Flat trim moulding between the bookcases, a stacked combination of foot moulding, plinth blocks and quarter rounds across the bottom and crown moulding across the top transformed everything!” 

The moulding adds personality to the build, as does the fabulous paint job. Aychel primed the IKEA furniture in KILZ and painted it from floor to ceiling in Needlepoint Navy by Sherwin Williams. “Suddenly, the bookcases were oozing with so much charm, character and personality, the result was even better than we could have hoped.”

18. Light up luxury media wall

This IKEA Billy bookcase hack brings a touch of glamour to IKEA’s well-known basic flatpack. Joseph of Joseph Anthony Design considered every inch of the final built-ins in his design and his attention to detail paid off. 

Joseph shared his top tips for successful IKEA Billy bookcase hacks with us “Here I achieved a more bespoke look by thickening all my shelves with 18mm MDF and adding LED lighting I can control with a remote. I have also wallpapered the back of the shelves, painted out the bookcases, and added new handles,” Joseph explained. 

Adding lighting to this budget-savvy DIY project was a smart move and helped create a relaxed ambience in the room as well as highlight Joseph’s handiwork.  

19. Organised playroom with entertainment center

An entertainment centre is a great home organisation idea for a small space while attractively housing a television and creating a stylish focal point in a room. Blogger Leslie Lambert’s brilliant Billy playroom hack is a fantastic example of a DIY entertainment centre comprising a tall Billy bookcase at each side and a short, wide bookcase to connect them.

The final product looks bespoke, thanks to the addition of crown moulding and baseboards. Leslie has a top tip for any DIYers keen to create their version, "when you're building, mark the location of the middle shelf on the back of your bookcase (before you put the solid white panel in). You'll need to nail this panel into place to secure it, and by marking the level of your shelf, you ensure you'll get your nails into that middle shelf and that they won't be exposed above or below it.'

This project, shared on Leslie's blog Lambert's Lately is a great example of why a smart Billy bookcase hack is such a useful tool. Happy with the final results, Leslie @lambertslately shares, "I am in love with the result of this IKEA built-in hack – I think it frames the room and, in addition to being beautiful, gave us some much-needed storage space."
