Located in the western suburbs of Shanghai, in the upper part of a 90s townhouse complex, House S was renovated and designed by architect Kailun Sun for her family. The original two-story interior was renovated with the addition of an attic, which functionally served as both a residence and an art studio. The renovation is guided by color, starting from the entrance space, and carrying out a series of deconstructing and reconstructing of the space around the original structure: using means such as opening holes in the space, restoring circulation, and introducing skylight, etc. All these together create opportunities for family members to communicate and interact when they are moving in the space, forming a living space that is interconnected and respectful. At the same time, the design explores the spatial expression of aesthetic emotions in the residence through the study of the relationship between color, circulation, and structural elements in the space.
