This 10x8 shed took 2 full days to assemble by 1 person with help from grandson to install roof panels.  Remove plastic coating before assembling. Basically you are screwing the pieces together using an electric drill or an electric screwdriver.  Use provided gloves  as this is sheet metal in order to avoid accidentally cutting yourself if you DIY. The shed is sturdy, roomy and secure with the provided door handle with keyed lock. It will hold a lot of lawn tools, even more than one lawnmower.  Would recommend.
