What is not in the 10.5 X 15.5 delivered package that I need when I assemble it?
This shed does not come with a floor, but with a foundation kit. You will provide the floor for this shed, whether it may be wood or concrete for instance. The kit provides a base for you to install the floor on, which would likely be used when a level surface isn't available. If so, you have the option to bypass the use of the floor kit so you may want to do that with an even concrete pad as the base. Beyond that, per the manual, all you need is a power drill, measuring tape, pliers and a ladder.
