This paper presents the implementation of two generative computational architectural design systems integrating regionalist inputs. While the automation of the design process using computational tools has been extensively discussed, the incorporation of regionalism remains limited. To address this, the Design Science Research method was employed to create computerized artifacts generating architectural models in BIM associated to Visual Programming Languages. The innovation lies in considering materiality requirements, building systems, and regional aesthetics as primary inputs for generating parametric shapes. The framework enables the generation of detailed BIM models, automatically documenting them to comply with local construction norms. This paper provides insights into the functionality of the generative algorithms, showcases the produced architectural instances, and presents the automatically generated 2D documentation. Additionally, a framework for a regionalist computational design approach is proposed. The study highlights the importance of incorporating regionalism and provides a foundation for the development of similar artifacts.
