Local building codes also dictate the type of foundation needed. Again, requirements differ from town to town, but in most areas sheds 10X10 ft. or smaller can be built on concrete blocks set on the ground. Larger sheds must be supported by poured-concrete footings dug down to the frost line. In most towns, the building inspector must examine the trenches or pier holes before you pour in the concrete. Siting the shed is another important consideration too many homeowners overlook.
Kids are much more likely to put away their bikes and sports equipment if the shed is close by.
Never build a shed at the bottom of a hill where water collects. And always leave at least 3 ft. of open space around all sides to make room for repairs and allow air to circulate freely. Which style you choose also brings some practical concerns. For example, sheds with gable roofs offer tall walls that are useful for putting up shelves and hanging long-handled tools. But they provide little headroom when you stand near the walls.
