How big of a storage shed do you need? This question is actually a bit tough to consider and answer. You have to take into account not only your storage shed needs now, but what you might need in two, five, or even ten years from now. Of course, what you build is going to be primarily determined by your budget. So I always advise, if you are planning to build something like a ten by ten or twelve by twelve, but you can afford to squeeze a sixteen by sixteen into your budget, then by all means you should go for the 16×16! And you can select a rubbermaid storage shed for your storage needs.
