Okie dokie. Tom with you again to take a closer look at the storage sheds that many of us call deck boxes or garbage containers. Otherwise known as extra large horizontal storage sheds. These are sort of the short and stout cousins of your standard vertical sheds. If you could imagine cartoon physics pushing down on a vertical storage shed, your end result would be a horizontal shed. I’m hoping that gives you a better visual than tipping a vertical shed on its side. Because horizontal outdoor storage sheds offer much more than that. Not all of them have doors, either. Some have lids! Here’s a review of ten of the best of them.
