How to Build a Trash Shed

Cut two 80-inch-long 2x4s. Glue and screw them together with construction adhesive and 2½-inch deck screws to make the top back crosspiece.

Set the top back crosspiece on edge on top of the angled support legs and flush with the roofline. Secure it with 2½-inch deck screws angled up through the supports.

Cut a 77-inch-long 2x4 to act as the middle back crosspiece. Rest it on the flat on top of the short 2x4 pieces and secure it to them with 2½-inch deck screws.
