A shed is typically a simple, single-story structure in a back garden or on an allotment that is used for storage, hobbies, or as a workshop. The modern Oxford English Dictionary (OED) defines sheds as a "slight structure built for shelter or storage, or for use as a workshop, either a separate building or attached to a permanent building as a lean-to; often with open front or sides."
Sheds vary considerably in the complexity of their construction and their size, from small open-sided tin-roofed structures to large wood-framed sheds with shingled roofs, windows, and electrical outlets. Sheds used on farms or in industry can be large structures.
