The IKEA Billy bookcase is an ultra popular piece. The bookcase has different size and color options, including white, black-brown, and birch veneer. And it's made primarily of particleboard. Overall, it's a simple and streamlined shelving unit with an affordable price tag.

However, what we love about this furniture item isn't just its storage capacity and budget-friendly price tag. We're also majorly enthusiastic about all of the DIY possibilities for you to customize Billy bookcases and make them look even better.

Sophisticated Storage

A Beautiful Mess

This Billy bookcase hack also used multiple shelves installed to appear like built-ins. They were painted to match the wall color to make them look extra custom. And they were jazzed up with a clever touch: storage bins in a corresponding color. Bins like these make it easy to stash away kids' toys, craft supplies, workout gear, and anything else that needs a home. And the top shelves still allow plenty of space for books and other display items.

Elite Entertainment Center

Sara Ann Sutton

These Billy bookshelves were transformed into an expansive entertainment center full of storage. The closed cabinets help to keep cords and wires concealed. And the open shelves provide plenty of space for media storage and knickknacks.

Life After Coffee / Jessica Bowen

If you're not sure what to place beside your fireplace mantel, built-ins (or a Billy bookcase built-in hack) might be the answer. Once again, the Billy bookcase—well, actually two of them—was made to look custom with some trim. The DIYer also chose to caulk the shelves to the wall to minimize the appearance of any gaps.

Bigger and Better

Chi Townhouse / Erica Graham

This is one of the larger walls of Billy bookcase built-ins that we've seen, and it looks beautiful. A custom bookcase like this could run thousands of dollars if you were starting from scratch versus the prefabricated Billy bookcases. The lower cabinets got doors with pulls that match the style of the space. And the DIYer chose to paint the walls to match the bookshelf color for a more seamless appearance.

Billy bookcases can look fabulous in the dining room, too. Here, a few bookcases grouped together make for ultra convenient storage for tableware, wine bottles, and other entertaining essentials. The addition of glass doors allows you to display your fancy dining items. If you don't need all the storage space that the tall bookcases provide, you can opt for the short variety and use the top as a bar or buffet.

Cool Cane

House of Hawkes / Kathryn Hawkes

Here we have another impressive Billy hack featuring caning. While many retailers sell similar pieces for hundreds of dollars (if not more), this one can easily be recreated at home with some basic supplies from IKEA and the craft store.

Light and Airy

This bookshelf is kept looking nice and airy due to the glassware and greenery present. Plus, instead of solid cabinet doors, it uses loosely woven baskets. It also makes use of the different sizes available of the Billy bookcase, as well as the adjustable shelves.

Formal and Fabulous

@magical_manor / Instagram

A robin's egg blue hue shines on these Billy bookcases and continues behind the fireplace to make the whole setup look custom. This unit proves that the Billy bookcase can look just as lovely in more formal living spaces as it does in casual family rooms. One trick to make your IKEA Billy bookcase look better is to display a limited number or type of items on the open shelves—e.g., only displaying books here—and leaving miscellaneous items for behind cabinet doors.

Clever Corner

@1930shouserevamp / Instagram

What's great about hacking a Billy bookcase is you can design an end product that truly fits your needs. And that can include manipulating things a bit to fit a tricky corner spot or angle in your home. The narrow Billy bookcase option can work especially well to fill in odd angles, and it can easily be used in conjunction with the more standard wider version because they're the same height.

Outstanding Office

@ourhome.becoming / Instagram

This Billy configuration doesn't go floor to ceiling or wall to wall, yet it looks totally built-in and custom for the office space. That's largely because the scale of the unit perfect fits its corner. So it feels like it was meant for that spot all along, rather than being DIYed from prefabricated Billy bookshelves. A sophisticated paint color, modern knobs, and traditional trim help to make the unit look classy and expensive in this home office.
