When you decide to purchase your home storage unit or shed, there seems to be a million screws to assemble along with it. In my experience in working with Ezra on said projects, he is very conscientious about assembling such projects according to specs. He also takes into consideration how the weather would affect the building in terms of leaks and proper foundation location.
This style is of foundation is an option that is cost affective.

For example, proper leveling techniques are used to avoid excess water or flooding.

Notice in the pictures the platform foundation:

1) How the building is protected from flooding.
2) Is given proper accessibility.
3) It is made to withstand strong wind, because it is secured properly
4) Since these foundations are gap-free they prevent any critters that may attempt to make this spot their home.
