The Cave of Earth is a pavilion located on the Loess Plateau in northern China. This region is known for its unique soil and challenging landscape. Designed to fulfill both functional and cultural roles, the pavilion makes use of local resources to create a structure that blends into its surroundings. The concept focuses on excavating the earth, using the loess soil available in the area to build a space that is in harmony with the environment and reduces reliance on conventional materials.

Rammed Earth Construction

Central to the Cave of Earth is a rammed earth column that serves as the backbone of the structure. This column is carefully constructed using methods that draw from local traditions. Its form is designed to resist lateral forces, showcasing the strength of loess soil. The construction involves excavating the earth to create sunken formwork, highlighting the connection between the architecture and the natural landscape.

Interior Spatial Dynamics

Inside the pavilion, varying depths from the excavation create interesting changes in height. This design encourages movement among visitors, guiding them to explore the space. Fixed furniture and exhibition steps are thoughtfully placed, ensuring that the pavilion serves its purpose effectively. The arrangement supports flexibility and interaction, allowing people to experience the architecture in an engaging way.

Interaction with Environment

The pavilion features two important openings that link it to the outside world. One opening is a pivoting door that faces the road, inviting visitors in. The other is a half-sunken staircase leading toward nearby villages, reminiscent of entrances found in traditional cave dwellings. This layout encourages a seamless transition between the pavilion and its surroundings, reinforcing the bond between built structures and the geographical context.

Sustainable Practices

The approach to sustainability is clear throughout the design. Efforts are made to minimize the use of new materials. The loess created during excavation is reused in construction, helping to reduce waste. Above the pavilion, a light canopy made from corn husks provides practical shelter while allowing sunlight and air to filter through. This addition enhances the pavilion’s connection to the local environment.

The light canopy serves as a distinct feature of the design, showcasing the thoughtful use of locally sourced materials. It provides shelter while keeping the space connected to nature. Together, these elements form a clear and functional space that reflects the landscape and the cultural heritage of the region.
