In the way of conventional architectural design, we usually think about site relevance, climate input, context connection and so forth. The site-based architectural design becomes the mainstream in the field of architecture today among the whole world. It is currently the practical and sophisticated way of designing, however, The mode of designing is turning to rigidity and template. It somehow limits the possibility of architectural design. When I study architectural design in the academy, I always think about Is there another approach to designing? The installation here is about the devices which are minor and subordinate to the architecture. It usually happens that we ignore its significance according to architectural design. Digging into the possible design of installation relating to architecture, the installation is actually an essential aspect of architectural design. The study of small devices could drive and lead the large final architectural design. In this portfolio, I would like to show how the small scale of installation study gradually lead and change the whole architectural design and ecology. Comparing to site-based architecture, the installation based architecture could be another approach for architectural design. During my 3-semester study of M. S. AAD at Cornell University, the study of an installation inspired and led my architectural design as always.
