Below is a pic of our recently completed junk drawer. The location is on top of the entertainment center. The new drawer & counter top raised the area 9". The drawer is 24" wide, 20" deep and 5" high.
Raising the area did create a problem by covering up the power & cable receptacles. So I made a cut out as shown below.
Our television, which we store under the seat, still has plenty of room and the addition didn't take away any counter space.
Now I'm ready for winter to get out of town.
