Abstract
A building system comprising a combination of precast or prefabricated structural elements to serve as skate parks, swimming pools, or community gathering places; and to provide refuge such as tornado shelters. Precast or pre-manufactured modular cells have an open bottom, a first and second side wall, a rear wall, and a functional top surface. The functional top surfaces of the modules include an inclined or curved surface. When combined, the top surfaces form useful areas such as a skate park, swimming pool, or amphitheater seating. Sleeves, keys, and other features facilitate the assembly of the modules. A cast slab may be poured after assembly; or the modules may be secured to a slab. Example modules include a Flat Ramp Block, a Circular Ramp Block, and a Circular Bowl Block, a stair block, and a ledge block.
