(1) A shed, abutting the wall of another structure, with three walls and a sloping roof. (2) A free standing structure of three walls and a sloping roof, the open side of which is sheltered from the prevailing winds. Used as a camping shelter.
An unlined covered area constructed so as to be supported by the exterior wall of a house, usually at the back. It was easier and cheaper, when piped water became available, to place laundry and lavatory facilities in such an addition, rather than to pipe it into the main part of the house. Lean-to's were also used as sheds. They were cheaper to construct and took up much less space.
