Standard wood pallets are 4 feet by 4 feet square in size making them perfect building material for sheds, bins or other construction projects that are square in shape. Wood pallets can often be acquired free of charge, especially if you live near a manufacturing facility as many raw components are shipped to the manufacturer on pallets. A few phone calls to local businesses could allow you to have all the pallets you need for a simple three-sided shed.
Layout 4 wood pallets in a large square shape and attach the pallets together using a hammer and 16-penny nails. This will create the sub-floor of your shed.
Place two pallets together and secure them using the hammer and 16-penny nails. Do this with the remaining wood pallets. These pairs will form the walls of your shed.
Erect the first wall section by standing the pallet pair on end and securing it flush with the bottom of the floor pallet edges. Erect the second pair next to the first and secure with 16-penny nails to both the floor and the first pallet pair. Place nails every two to three inches for added strength and stability.
Repeat this process for the opposite wall.
Secure the back wall in the same way to the floor. Secure the panels together just as you did the sidewalls.
Attach the back wall to the sidewall by nailing the pallets together using 16-penny nails at least every two inches.
Nail the plywood to the floor using 8-penny nails.
Nail the four 1 X 6s evenly across the top of the shed walls, again using 8-penny nails.
Secure the roofing tin to the 1 X 6s using roofing screws every two inches. Apply silicone caulk around each roofing screw to insure that the roof will not leak.
Doors can be added to the open side by using 4 X 8 plywood and hardware hinges. If desired, treated plywood can be secured to the outside of the shed to fully enclose the space.
