Measure and Cut Bench Frame

Measure the bench frame area. Cut 2x4 boards with a miter saw to create the frame.

Step 8

Install Bench Frame

Remove any existing baseboard trim. Install the lengths along the wall using 2-1/2-inch screws (Image 1). Attach the shorter pieces of 2x4 boards to create the outline of the frame (Image 2).

Step 9

Attach Bench Skin

Measure the frame and use a circular saw to cut plywood pieces to create the skin (Image 1). Attach the skin with wood screws, and work your way around the frame (Image 2).
