Before you start, plan your project carefully. Consider the size of your Billy bookcase, the space you have, and the look you want to achieve. Measure the wall space where you'll install the bookcase, and ensure it's level. Decide whether you want the bookcase to span the entire wall or if you'll incorporate other elements like doors or cabinets.

Begin by disassembling your Billy bookcase. Remove the shelves and back panel. You'll also need to remove the adjustable feet at the bottom. Keep all the hardware and screws organized for reassembly later.

Create a Backing and Sides

Measure the width and height of your wall space. Cut plywood or MDF to create a backing panel that fits snugly against the wall. Also, cut side panels that will extend from the floor to the ceiling, creating a built-in look. These panels should be slightly wider than the depth of your Billy bookcase to accommodate the sides of the unit.

Assemble the Built-In Structure

Apply wood glue along the edges of your backing panel and side panels. Attach the side panels to the backing, ensuring they're level and flush with the edges. Use screws for added stability. Let the glue dry according to the package instructions.

Reassemble the Billy Bookcase

Measure and cut trim and molding to fit the sides, top, and bottom of your built-in unit. Attach these using wood glue and nails or brad nails. For a seamless look, use crown molding at the top and baseboard at the bottom.

Paint or Stain Your Built-In

Sand any rough edges or nail holes, then apply a coat of paint or stain to match your room's color scheme. Allow the paint or stain to dry completely between coats. For a more finished look, consider painting the trim and molding a different color than the rest of the unit.

Caulk and Touch Up

Use caulk to fill any gaps between the trim, molding, and wall. Allow the caulk to dry, then sand and paint any touched-up areas. Your Billy bookcase is now transformed into a beautiful, built-in unit!
