Over 30 million people in China live in energy-efficient caves! Some even have electricity!
I guess, when stuck between a rock and a hard place, these people chose the rock option.
In China, more that 30 million people find their shelter in caves. However, these unusual forms of housing are more comfortable than you might think.
The Loess plateau, located in the Shaanxi province, is very distinct. Known for its cliffs made of yellow, easily-pliable dirt, it acts as the primary site of China’s cave dwelling citizens.
Many people reinforce their caves with brick structures. Some connect multiple caves together to create larger homes. Families can even bring in running water and electricity.
By their nature, caves act as their own air conditioning and heating system, providing warmth during the winter and cooler temperatures during the summer.
Further, caves are one of the greenest forms of housing available, as their designs generally work with nature, not against or in spite of it.
Because of their popularity, caves provide a solid investment for real-estate speculators. For example, a 750 square foot cave can be sold for almost $50,000, with higher-end caves going for much more.
