Hillside Dwelling is a guest room situated on the 28th floor of New Everbright Center • ArtPark9, Tongzhou District, Beijing. Dwellings of mankind have been changing with time. In the primitive period, people lived in caves. Based on reflections on the evolution of human beings' dwellings, the designers tried to return to the origin and essence of living spaces and stimulate the interaction between people and the outdoor environment.

In the rectangular guest room, the floor is raised from the bottom of the large French window to the ceiling gently, which forms a hillside-shaped structure and generates three-dimensional relations between people inside the space and landscape outside. Based on people's living behaviours and body size, the designers created five basic functional areas within the space, including the entrance and the washroom in the caves under the hillside, areas for sleeping and bathing which are on the best place of the hillside to enjoy the outdoor view, and the area for walking and resting on the lower part of the hillside. The hillside is covered with cork boards, featuring a soft and warm texture. All the caves can be taken as bespoke furniture, with their functions being defined by body size and physical behaviours. Besides, the space is equipped with some necessary modern facilities such as a mini bar and a projection screen, which are hidden on the wall and ceiling, ready for use at any time.
