The project is located in a commercial and residential apartment building in Pudong New District, Shanghai. The owner is a single female lawyer. This 80 square meter apartment is oriented to the north, without direct sunshine. The original apartment is a frame structure of one room and one hall. Considering that the owner lives alone and the light is dark, the designer breaks through the partition walls of two rooms to form an open space. The whole space adopts two colors, warm and cold, and the curvilinear modeling process, while satisfying the functional needs, increases the user’s different sense of experience, which is consistent with the owner’s preference for color.
