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.

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.
