I want to do something like this photo but I don't know how to attach the one-step platform thing:
I circled two areas that should be attached by nails (assuming 16d Common Nail). But the photo shows they are not attached on the right side.
My question is: how to property attach the lower stair like this case? Or should I just submerge it into concrete in some part?

I wouldn't submerge anything, and ensure that all post holes are filled in concrete and sealed from any water. . With stairs and raised floors eliminate any source of water to prevent wood rot. With the cost of materials these days you can't afford a failure due to rot Anywhere!
