Abstract
The present invention pertains to the construction of modular structures used as a building blocks to create an habitation or integrated structures which form habitations. In both cases flexible molds are injected with mold materials to form the final structure created. An outer cavity of the mold is first inflated to create either a finalized shape of the structure or a partial shape for the structure. If internal constraints of the innermost cavity are already included, a finalized structural shape is obtained. If internal constraints for the innermost cavity have to be added, the final shaped is obtain after those constraints are placed within the innermost cavity.
