Design and Build Steps for a Prefab Shed

Picture of Design and Build Steps for a Prefab Shed
During a recent move, I took down my prefab steel shed and brought it to the new house. In our old place, the platform the shed was built on was flimsy and placed directly on the ground. Here, I wanted something sturdier and more weatherproof, so I put it up on piers, level, plumb, and square.

It was also 20" off the ground.

This made it hard to get in and out of the shed, so I knew I'd have to build steps. This is the design process I went through. Total cost for this project was $0. I used lumber salvaged from pallets and building site refuse, and hardware left over from building the shed platform.

I'm entering this into the Instructables Design Competition. If you like it, please vote. Thank you!

Step 1: Measure, Inventory, and Think

I knew right away that I wanted the treads on my steps to be made from some boards I'd salvaged from a pallet. They were 1" thick, 5.5" wide, and 40" long, with nicely rounded edges. The height of the shed platform off the ground was 20" on average, and it had an overhang that was 6" thick and extended 6" from the first joist.

I designed the two steps to be a separate structure, in case I ever need to move them out of the way. I wanted them to slide under the overhang, so they needed to be no more than 14" tall. Two steps in 14" meant each would be 7" tall. To compensate for the overhang, I made the upper step one tread board longer than the lower step.

I planned to use standard 2x4 lumber for the supporting structure. I lack the tools to make mitered cuts in a 2x6 or similar, and I hoped that the design I chose would be sturdy using just 90º angles. It should be noted that 2x4 lumber is not actually 2" by 4". I drew the design as if it were for the sake of simplicity. In the actual construction, I measured everything from what was at hand, not relying on the measurements in the drawings.

I like the simplicity and flexibility of this design. I am going to use it for temporary stairs to a deck I just built. Thank you. Great work!
