Assembled this recently on a new wooden foundation.  It has lots of floor space and headroom and looks great, plus is secure and lockable.  Take time to read the instructions carefully; the online videos and tutorials help.  Some of the screws are used in several places and with bags or boxes that are not always labelled correctly.  Consider putting all identical screws in the one bag and call it Bag S-1 or similar.  Also, the shed comes in 2 boxes, each around 200 pounds - back-breaking.  Consider using 3 or even 4 boxes.  But overall, the shed is great - well designed, solid, and worth the work to assemble it.
