Abstract: A leveling system for a shed or other pre-fabricated building. The system includes a series of concrete supports and bases for receiving the vertical support arms for the shed. The bases each have pivot points to receive slant support beams. The pivot points allow the user to place the slant support beams to the correct angle depending on the incline of the terrain. The bases also have the capability of receiving mechanical fasteners, such as screws, to stabilize the support system to the concrete bases. The system can be used in several places beneath the shed, to compensate for uneven terrain in different places beneath the shed or prefabricated buildings.
