Design Integrated Parametric Modeling Methodology for Han-ok

Han-ok, the traditional Korean house, has the timber frame structure which is common in East Asia. Because the timber frame structure requires a vast amount of hand-cutting woodwork, prefabrication based on computer aided manufacturing (CAM) should be applied to reduce the construction cost of Han-ok. In order to implement them successfully, it is necessary to manage the building information in an organized system based on data handling technology, such as building information modeling (BIM) and parametric modeling. Three-dimensional, object-based parametric modeling technology not only enhances the construction process but also associates well with design study, especially when applying it to Han-ok. By applying the principle of Kan, the Korean traditional concept of a bay, this paper suggests a parametric modeling methodology that reduces modeling tasks and increases the efficiency of design study.
