The purpose of this study is to propose an alternative of architectural space planning which can form a new space through regeneration of modern industrial heritage. For this purpose, this study examines the modern industrial heritage regeneration methods, and proposes the architectural space plan that embodies the history and physical changes of overlapping time of existing buildings based on the concept of the layer. The contents of the proposed design plan in this study are as follows. First, expressed the time layer inherent in the building by preserving the architectural elements that symbolize the functional characteristics of the site. Second, formed the functional layer so that the four separate buildings in the site could be recognized as a cultural complex. Third, revealed the physical layer and the material layer by preserving the form and the material of the existing building and making the added space visually distinct. The proposal in this study has a meaning as a new alternative of the reconstruction plan of the building which can embody the history of time superimposed on the building as physical entities.
