The extent to which script-based design and scenario design method is employed in the shaping of interior space is relatively little compared to that of other design areas, such as product and visual designs. The application of such a procedure, which functioned as sieves and filters, could enable a more thorough design outcome. In order to improve the quality of interior design, and to reduce missing, or wrong decision making, script-embedded method would be able to generate images with holistic details for later assessment. That is, scenes of interior ambiances are to be decomposed and evaluated in terms of diversity, integrity, and priorities. In short, this study examines studies relevant to script scene decompositions and demonstrates the way it is done by way of interior space containing potential activities of diverse scenarios. Based on the results, it is concluded that the construction and analysis of the script-embedded scenario design method are essential and that the tool is useful for designers.
