Metal sheds are helpful to store outdoor gardening or other tools. However, being made of metal, rust can often appear after rain storms or when the lawn sprinklers are in use. Help prevent bottom rust to a metal shed by constructing a small, raised structure to keep the base of the shed off the ground. You only need some simple supplies and a few hours to complete the project.

  1. 1

    Measure the space you have chosen to place the shed. Use the wooden stakes to mark all four corners, and wrap string around each stake. Make sure the shed is unobstructed from hedges, bushes or fencing. Make sure the area marked is a perfect square on all sides.

  2. 2

    Till away roughly 2 to 4 inches of top soil for a smooth surface. Use the spade to dig out any excess areas you need to get a smooth surface. Use a level and make sure the ground is level on all sides.

  3. 3

    Use the saw to cut four of the 2-by-4 wood planks into the desired length of the base stand. If you have a shed that is 6-feet-long-by-6-feet-wide, the stand should be at least 8 feet long and 8 feet wide so the shed will rest on it evenly. Use the hammer and nails to connect all four of the corners together. Then use the drill and wood screws to anchor the wood planks to each corner. You will have nails on the outer sides of the planks and the wooden screws going through the inner corners.

  4. 4

    Cut four more pieces of the planks and centre them in the middle of the square. Measure the distance from the inner edges of the side boards. Divide this area by four, and mark the approximate location for each stud plank. Lay your stud planks by the marks and measure again, making sure they are all the same distance from each other and the side planks. Remark if necessary. Hammer the nails into the boards to connect them to the planks.

  5. 5

    Measure the square to the outer edges of the planks. Use the saw to cut the two plywood pieces into equal lengths, the same length as the square and each half the width of the square.

  6. 6

    Attach each plywood sheet to the wooden planks using wood screws. This will create the flooring for the structure. Find the support studs and hammer nails from the top through the plywood sheets to help secure the structure. You will have a solid, squared, raised structure for the shed.

  7. 7

    Place the yard anchors in each of the four corners of the structure. Connect the end of the anchors to the wood-plank corners using heavy wood screws and a screwdriver. Tie the other end with the rope and pull tight, then attach to the yard-anchor stakes and push them securely into the ground. This will allow for additional support in case of strong winds.

  8. 8

    Measure the structure to make sure it is squared off and level to the ground. You can now place the shed on the top of the raised structure.

Tips and warnings

  • When placing materials in the shed, make sure you evenly distribute the objects by weight. You want to keep a balanced shed so the base will not sink or crack under the added weight pressure.
  • Always wear proper safety gear, such as goggle and gloves, when building.
