Sturdy. Easy to assemble. Better to have two people assemble. One can do it with no problem.

Reviewer: '49 Merc Man from    5 Stars

I have an 8 x 5-ft shed. And it is a great shed / shop. The ONLY complaint I have was attempting to snap the corner / wall segment tabs into the flooring slots. That was extremely difficult if not impossible. Simply pulling down on these segments to install corners / walls into the flooring did not work for me... the best method was to place the corner / wall segments in-place on the flooring and spray the tabs / slots with WD-40. Bingo!... also, I would suggest purchasing the shelving vertical bars to strengthen the side walls.
