I made this washer/dryer platform with two 2x12's (cut into 2-58", 5-25"), 2 sheets of 3/4" plywood (cut to 2- 58"x28"). The lumber was screwed together like a wall form; then the plywood screwed to the top and bottom to close in the form. I put bead board and trim (painted with oil based paint) on the outside of the form to "pretty it up" The total cost was approx. $110, saving me $400 if I had purchased the pedestals.
