The invention comprises a composite spatial structure and its constructional design. The composite spatial structure consists of two elements: 1) metallic spatial grating and 2) concrete slab. The metallic spatial grating is prefabricated in the workshop and transported on site. The concrete slab is forged using the ground as shuttering (formwork) and subsequently the modules are raised with mechanical cranes and located in their definitive position on the columns. The invention applies to the construction industry.
