This shed looks great and is very sturdy.  we built a wooden platform and screwed the corners of the shed to it.  we did this as the last step so we could easily access the back of the shed for construction if the walls and roof.  it took two of us to build it.  we are very experienced and found parts of the construction to be challenging.  the instructions are very good, but read them carefully and look ahead to be sure you have things lined up.  peeling the shrink wrap off of all pieces was tedious!
