The combination of “logic belt” and “magic belt” bring new life to the old flat. The twisted mirror polished stainless steel vortex connects the north and south, solving the lighting, ventilation and scale problems in one single step. However, this does not mean the end of the design since the organization of service space was not perfect for a design studio. Practicality and rationality are equally important compared to dreams and romance. The design attempts to convey the philosophy: Logic & Magic (follow the logic, create the magic) through rational arrangement of service spaces. The twisted mirror polished stainless steel vortex connects the north and south, solving the lighting, ventilation and scale problems in one single step. The surrounding scenery is incorporated into the “magic belt” and flows into the interior along its surface. The vortex gradually shrinks in the lounge area and form the fishtail bar in the end, which not only realizes the function but also avoids direct sight from the entrance to the workplace. A series of structure studies optimized the construction logic of the stainless steel itself. The form of the ground-supported portion and the tension of its shape partially reduced the difficulty of construction. Different from the traditional obstructive scenery, the material and curvature of the silvery vortex make it reflect the extraordinary dimensionality of the surrounding space, both modern and magic. The renovation of the office give an example of how Shanghai's 40 million square meters of stock housing can be transformed and how design can activate and bring vitality to our everyday life.
