A new grid system generated from original architectural system served as a control system for the facade and internal space. In view of irregular floor height and column grid structure, a curtain wall framework structure was linked to original framework structure, thus matching the structural logic and also reflecting the basic conditions of original building with its own unique language. The 3D external grid space helped to form an internal space with different depth and characteristics (Fig.3). A 3D gallery (Fig. 4) was located at western wide, an office & lobby at northern side (Fig.5), and chairs and ventilation facility at southern side (Fig.6). The concealed curtain wall structure could control the sunlight and view, and white-colored glaze glass of different transparency endue it with tranquil, soft and implicit style (Fig.7).
