Abstract: A suspended slab (14) is spaced apart from a surface of the ground (18) by a void space (20). Structural supports (16) are provided to extend upward from the ground (18). Removable supports (22) are placed on top of the ground (18) and extend upward to a desired height. The suspended slab (14) is poured on top of the removable support (22), suspended at least in part by the plurality of structural supports (16). The removable material (22) is removed after the material of the suspended slab (14) sets, leaving the suspended slab (14) suspended by the structural supports (16) with a void space (20) of the desired height extending between the bottom of the slab (14) and a top side of the ground (18). An enclosure skirt (26) is placed around a perimeter of the suspended slab (14) to enclosed the void space (20).
