Tool-storage structures are structures specifically designed to store tools. Sheds are a common example of such structures, typically made of wood or metal and used to store garden tools, lawn mowers, and other outdoor equipment. Sheds can also be used to store items such as bicycles, furniture, and other items that need to be kept out of the elements. They are often found in backyards, but can also be found in other areas such as parks and public spaces.
