"Storage shed" covers a range that runs from a $243 flat-packed metal box to a $4,799 wood building put up for you — roughly twenty times, under one category name. The middle rung is where the category is actually moving. A resin shed at $900 to $1,100 is no longer a tool cupboard: wood-grain walls, a window, a floor, double doors, and no repainting. It costs more than metal and asks far less than timber. U.S. demand for sheds and residential outdoor storage is forecast to reach $3 billion by 2029.
Two things follow from the ladder. First, the cheap metal rung is a commodity race — bigger, thinner, cheaper — and it is a poor place to enter. Second, and more useful: a buyer who has just spent four figures on an empty shell then has to fit it out. Shelving, wall track, bike and tool racks, mower bays, a workbench, lighting. That second purchase is the wholesale opportunity, and it repeats — the shed is bought once, the inside of it is bought again. It is the same demand we see indoors in the two-car garage, and it tracks new housing permits with a lag. See our storage and warehouse range.
