Cave of Rammed Earth

Yumeng Hong & Zhengqing Tan

A Kidville as an imagination of the home in 100 years

As the environment deteriorates, desertification becomes more and more severe in the future, and the population grows, and the inhabitants of many areas are forced to settle in the desert. Taking a village in the desert region of Northwest China 100 years in the future as an example, we discuss how families with 1-2 children can raise their children in a house made from local sand resources, hoping to warn people today to protect the environment and control population growth.
After researching the local situation, interviewing the people and summarizing their needs, we conducted a lot of material experiments and designed a new type of rammed earth concrete. It can transform sand into a building material that is easy to shape and has good diffuse reflection, which is conducive to more uniform interior lighting in interior spaces, creating warmth and better and more uniform lighting, and creating a sense of warmth and atmosphere. Its cheapness makes it affordable for the poor in the future.
Inspired by the private nest, the interior space form of the home is mainly based on free-form curves and arcs, taking into account the characteristics of the place needed for parent-child activities, and to prevent children from bumping into each other. We used modular design, the volume of the building can be adjusted to the number of bedrooms according to the number of people, saving resources.
We made a physical model to verify the interior experience, and the different spaces are connected to each other to provide a space for intimate communication between families. We also designed a parent-child activity area with a sunken floor so that children can lie down and play freely in it. The living room is a shared space where the family can chat, read a book, work, listen to music, etc. in the same space. We also designed a large number of niches embedded in the walls for storage, as well as a variety of different spatial furniture.
In general, we design a home 100 years from now that will actively address the issues of population and desertification, providing a warm, comfortable and secure home that is affordable for ordinary people, and a playground and parent-child space for children that responds to their active nature.
