A storage shed can be a very useful space when used appropriately. However, since it's a space that is used for utility, homeowners often don't give much thought as to how it is arranged. During the spring and summer months, yard tools are frequently hulled in and out to assist in landscaping projects. In the winter, you may have to scramble to find snow shovels and sleds, certainly not something anyone wants to do in a harsh winter.
If the clutter on your property says one unit isn't enough, but your wallet disagrees, supplement your main unit with one of the less expensive, smaller models. There are three main types of such units, all of which go by descriptive names. $Corner sheds$ are made to fit precisely into a corner and run about 3 feet tall by 3 feet wide by 2 feet deep. Meanwhile, either a $vertical shed$ (5 x 3 x 4) or a $horizontal shed$ (3 x 5 x 4) may be just the handy outdoor storage building to fill your need for additional space.
