Step 1: Construct the Base and Install Wall Cabinets


Start by building a solid base for the cabinets. This raises them off the floor, giving your DIY media wall a custom, built-in appearance. Use 2×6 boards for a 6-inch lift or 2×4 boards for a more budget-friendly option.

  • Build the Base: Cut 2×6 boards to the correct length and assemble the frame. Ensure it is sturdy enough to support the entire entertainment center.

  • Secure the Base: Attach the base to the wall studs for stability.

  • Cover the Base: Place 3/4" plywood on top to create a solid platform for the cabinets.

Next, position the cabinets:

  • Position the Cabinets: Place the upper and lower cabinets on the base, ensuring they are level. Secure them to the wall using 3" wood screws.

  • Middle Cabinet Bump-Out: If the center cabinet sticks out, use 2×4 spacers to align it with the other cabinets.

Step 2: Install Tops on the Cabinets

Once the base and cabinets are secured, install the tops.

  • Cut the Tops: Using 3/4" sanded plywood, cut three tops that align with the sides of the cabinets.

  • Secure the Tops: Drill pilot holes and attach the tops to the cabinets using wood screws, creating a solid foundation for the shelving units.

Step 3: Build the Upper Shelving Towers

The shelving towers are the focal point of your custom media center, offering both storage and style.

  • Cut the Side Panels: Cut four identical side panels from 3/4" plywood for the outer and middle sections of the shelves.

  • Determine Dimensions: Make the panels 1 inch shorter in depth than the base cabinets and match the width to the cabinets, minus panel thickness.

  • Drill Pocket Holes: Prepare the panels for assembly by drilling pocket holes.

Cut and assemble the shelves:

  • Cut the Shelves: Measure and cut shelves to fit between the side panels. Dry-fit them to ensure proper alignment.

  • Assemble the Shelves: Use wood glue and pocket hole screws to assemble the shelves securely.

  • Attach Back Panels: Attach 1/4" MDF panels to the back of each shelving unit for stability and a smooth surface for painting.

Finally, secure the shelving towers to the wall:

  • Secure to the Wall: Use hidden cleats to anchor the towers to the wall studs for added stability.

Step 4: Add Trim for a Built-In Look

For a polished, custom appearance, add trim to your DIY media wall.

  • Baseboards and Top Trim: Attach 5 1/4" MDF baseboards along the bottom to match your room's baseboards. Add 1×6 MDF boards along the top for crown molding.

  • Crown Molding: Cut and attach the crown moulding with a brad nailer to give the unit a seamless, built-in look.

  • Side Panel Trim: Cover exposed cabinet sides with 1/4" plywood for a finished appearance.

  • Face Frame Trim: Use 1×2 MDF boards to trim the front edges, covering rough cuts and giving the unit a clean finish.

Step 5: Caulk and Fill Gaps

For a professional-grade finish, fill gaps and seams.

  • Caulk Seams: Apply caulk to all joints where trim meets the wall or other surfaces.

  • Fill Screw Holes: Use wood filler to cover screw and nail holes, then sand smooth.
