This project is on the east side of the roof of the shopping mall. It is a U-shaped space enclosed by rooms with different functions. The project is not big, covering a floor area of 320 square meters and a building area of 220 square meters. A cuboid is inserted in the U-shaped space, and a wall is built on the open side of the U shape to ensure privacy. Spaces are left between the cuboid and the wall for building a courtyard and patio. Bamboo is planted all over the courtyard and patio, creating an image that the building is hidden in the bamboo forest.
