Select a spot on your lawn to place your shed. It should be flat, level, and have good drainage.
Place the roof panel on its side and have a helper hold it in place. Place the right-hand side wall (all parts are marked) on its side and line up the tabs in the wall with the slots in the right-hand side of the roof panel. Push the wall into the roof panel until it snaps into place. Repeat for the left-hand side wall.
Lay the back wall in between the side walls. Make sure the words "back panel" are facing upright. Push the tabs in the back wall panel into the slots in the roof panel until it snaps into place.
Slide the floor panel in between the side panels and push it down until the tabs in the floor panel snap into place on the back wall panel. Make sure the word "floor" on the floor panel is facing upward toward the roof panel. Use a rubber hammer and lightly tap the floor panel until it snaps into place if necessary.
Stand the shed assembly in an upright position in your desired location, with help from an assistant.
Place the upper hinge pin of the right-hand door into the hole at the top of the shed opening on the right hand side. Swing the bottom of the door into place and allow the lower hinge pin to drop into the bottom hole of the opening. Repeat for the left-hand door.
