IKEA Billy Bookcase Built-In Hack (Step-by-Step Guide)

I wasn’t about to drop thousands on custom shelves. So I figured it out myself. I grabbed 3 IKEA Billy bookcases, some trim, paint, and got to work. Now I got a clean built-in look that people think cost a fortune — and I’m showing you exactly how I did it.

This guide is just $1. No fluff, no fake influencer vibes. Just a real one showing how you can make your space look expensive without spending like it.

Here’s what you get:

• My full list of tools and materials
• Step-by-step instructions (easy to follow)
• How I did the trim and paint
• My exact budget and what I’d change next time
• No gatekeeping — everything laid out

You don’t need to be a pro. If you got basic tools and a weekend, you can do this. Whether you rent or own, this is the kind of upgrade that makes your spot look high-end on a broke budget.

Download it, peep the steps, and get it done your way.
