A lean-to shed will give you a lot of storage space for minimal cost and effort, and is far more satisfying and solid than any pre-purchased box. you can keep the plan very basic, or add on more permanence with walls and flooring � or even just by using a tarp to cover the outside in winter.. Afterwards, you have to build the back wall of the lean to shed and to install it on the flooring, in the same way described above. as you can see in the image, you have to cut the top of the wall studs at 17.5
