The relationship between form and structure is a topic that, historically, has been broadly discussed in the disciplines of architecture and engineering. Taking some of these precedents as reference, this thesis focuses on the development of a combinatory modular system that integrates expressive forms and structural principles. This is achieved through the implementation of geometric and structural parameters as well as industrial processes and material properties from the early stages of the design process. Through this design approach, expressive forms move away from personal and figurative references. Moreover, this modular system reevaluates the role of industrial mass production and the new opportunities offered by digital prefabrication methods through the development of a combinatorial assembly system of structural modules at multiple scales.
