Building a Shed Foundation

  • 2 — two band boards
  • 4×4 skids
  • 16d galvanized common nails
  • 8d galvanized common nails
    1. Cut floor joists, 2 rim joists, two band boards, and skids to proper length.
    2. Mark off two band boards for the joist layout at 12” on center.
    3. Use the 16d galvanized common nails to assemble the frame. Check each joist for crowning and then install it with the crowned edge up.
    4. Lay down the skids evenly spaced and lined up on the foundation. Ensure they are level.
    5. Put the floor frame on top of the skids.
    6. Measure the diagonals to ensure it is square.
    7. Nail all joists to your skids with the galvanized nails. Measure 4’, 8’, and 12’ to ensure the skids are nailed exactly on center. This will allow your edges to fall in the middle of your joists when you lay down your decking.
    8. At this point, you will need to anchor your shed down. Do this before you put down and nail the floor sheathing.
    9. Lay down floor sheathing. Start with the front corners. Nail in 8d galvanized box nails every 6” along the edges and every 12” in the field.

      Building the Shed Walls

      You can start with any wall you want. Build off of the surface of your shed foundation.

      • Wood plates for walls
      • Siding for walls
      • 16d galvanized box nails
      • Scrap 2x4s
        1. Measure and cut the top and bottom plates.
        2. Place them together and mark off locations for the wall studs and door studs location.
        3. Cut the wall studs and door studs. Lay them in between the top and bottom plates.
        4. Nail into place.
        5. Cut all the siding for your walls to the specified length.
        6. Start on the left side of your wall. Line up the first piece of siding so the top plate and left wall studs are flush with your siding. Lay the siding down so the laps fall correctly.
        7. Nail siding into place with 8d galvanized box nails every 8” on the top and bottom plates, as well as on the inside studs. DO NOT nail the inside lap at this point in time. You will not nail the inside lap until the next panel is put into place.
        8. Extend the siding at least 1 ½” below your bottom plate.
        9. Nail the rest of the siding panels in place. Keep the top edge of your siding flush with the top plate.
        10. Nail the top plate to the siding. Line up the seam and nail it.
        11. Continue nailing the rest of the panel to keep the wall square.
        12. Have a 2×4 already nailed onto your wall so you can use it for nailing to the floor. This will keep the wall in place while you nail the bottom plate to the floor.
        13. With 16d galvanized nails, nail wall into place by standing it up.
        14. Nail near each wall stud into the floor joists. Make sure the wall ends line up with the edges of the floor.
        15. Assemble the rest of the walls following the above steps. Start with the left panel, then do the 2 door panels if you are building a saltbox shed. Make sure to keep the edge of your panels flush with the top plate.
        16. Use the scrap 2x4s as a temporary brace to keep your walls up.

          Building your Shed Doors

          This is likely the hardest part of building a shed. Consider building them before you build your walls.

          Decide what size door you need. You will want a bigger door to ensure that you can get your big equipment in, such as a large riding lawn mower. A good size is 6’. If you are making a saltbox shed, lay the doors onto your wall studs and nail them into place.

          Raise the wall on your floor and the front wall is complete.

          Building a Shed Roof

          • Lumber
          • Framing square
          • Nails
          • Covering
          • Nails
            1. Install the beams on the top. Do this by joining the four beams and placing the frame on top of the shed. The beams should be an inch thicker than the walls. This allows for better support. Use the nails or bolts and carpenter’s glue to fix the beams on the top.
            2. Construct the rest of the roof. For a gable shed roof that has vertical and horizontal beams, attach an elevated beam in the middle of the vertical beam.
            3. The beam will be perpendicular to the horizontal beams. The elevated beam will be 2 ½ or 3 feet high.
            4. Diagonal rafters are needed to support the type of roof covering you choose to use. Measure the distance from the elevated beam to the base and cut out a diagonal rafter.
            5. To make sure the rafter is stable when it is fixed down, cut a stopper at the bottom.
            6. For even more stability, cut multiple rafters for both sides of the frame work. Attach rafters by fixing the rafters into the base beams.
            7. Nail them down.
            8. Once rafters are secure, it is time to cover the roof. Use sheet iron or thick plywood. Allow for an overlap for appearance.
            9. Nail them down to the rafters.

              Once you cover the roof, your shed is complete. These simple steps for building a shed will help you create a place for storage in just a few hours.
