When working with power tools, use extreme caution.

If you are in need of additional space to store unused items and tools, purchasing a storage shed can be helpful. The job of constructing a storage shed that is 5 feet by 10 feet and has a simple flat roof on terrain that is already level may be accomplished with the investment of a few days’ worth of labour. To construct one, you will only need a few standard tools, as well as four different kinds of timber and components.

To construct the foundation of your shed, cut the boards measuring 6 by 8 inches. You should now have four parts that are 10 feet long and eight pieces that are 4 feet and 1 inch long.

On the surface that has been levelled, using six 6-by-8 boards and penny nails, construct the first layer of the floor’s structure, which measures 5 feet by 10 feet. Form a rectangle by placing two of the 4-foot-1-inch 6-by-8 boards on the broad edge between the 10-foot 6-by-8 boards (also place these boards on the wide edge). Put the remaining two 4-foot-1-inch sections within the frame so that they are perpendicular to the 10-foot pieces and spacing them out evenly. This will provide support for the floor. Attach them to the 10-foot-long sidewalls of the enclosure.


Perform Step 2 once again and construct another piece of the frame right on top of the previous layer using the six 6-by-8s that are still available. Penny nails should be used to attach the two layers of the frame to each other.

Align the piece of plywood measuring five feet by ten feet and three quarters of an inch thick over the frame. To attach it, drive nails that are two inches long down through it all the way around the frame, including the support beams.

  1. Determine which of the four walls will house the entrance before beginning construction on the other walls. A doorway that is 3 feet wide and 7 feet tall gives a generous amount of space. To construct the frame, attach two 2-by-4s to each side and one along the top. Integrate the entryway into the wall frame as much as possible.

  2. Utilizing 2-by-4s and nails 2 1/2 inches in length, construct the rectangular frames for the two 10-foot walls. Each frame is comprised of four individual parts ranging in length from six feet and nine inches to ten feet. Between the top and bottom parts that are 10 feet long, add some 2-by-4s that are 6 feet 9 inches long for the vertical studs, and spread them out 8 inches apart.

  3. Construct the two walls with a height of 5 feet such that their length is 4 feet 5 inches. They were able to squeeze through the 10-foot barriers.

  4. Stand all four walls up around the plywood floor. Fasten them to the plywood foundation with nails measuring 2 1/2 inches every six inches all the way around, then nail them to each other at intervals of four inches from top to bottom.

  5. To construct the horizontal supports that run the length of the shed’s flat roof, cut five 2-by-4s measuring 8 feet in length. Place them in a flat layer across the two walls that are 10 feet long and parallel to the walls that are 5 feet long, and evenly spacing them out. Use nails measuring 2 1/2 inches to attach them to the tops of the wall frames.

  6. Place the second piece of plywood measuring five feet by ten feet and three quarters of an inch thick on top of the roof supports. Nails of 2 inches in length should be used to attach it to the supports.

  7. Apply a layer of plywood with a thickness of half an inch to the outside of all four walls of the shed. Nails measuring 1 1/2 inches in length should be used to attach it to the studs.

  8. The use of tin as a shield for the roof is highly recommended. Make cuts and fasten the pieces onto the roof.

  9. Use doors made of lightweight plastic that have been trimmed to suit the doorway, or make your own doors out of plywood and cut them to fit. Use hinges with a heavy-duty capacity to hang your doors.

  10. Align the other 5-foot-by-10-foot sheet of 3/4-inch plywood over the roof supports. Attach it to the supports with 2-inch nails.

  11. Cover the outside of all four shed walls with 1/2-inch plywood. Attach it to the studs with 1 1/2-inch nails.

  12. Add protection to the roof using tin. Cut pieces and nail over the roof.

  13. Use lightweight plastic doors cut to fit the doorway, or cut your own using plywood. Hang your doors with heavy-duty hinges.
