I recently found these houses and was really interested in them because of the community centric design aspects. The hakka houses have lots of smaller “apartments” in them so that many families live in them. These circular houses have stood since the 17th century where their high exterior walls made of rammed earth kept marauders at bay.
This style of housing is from a particular region of China where they have formed self sustaining communities, where most of the food, goods and other products are made by residents to meet the needs of the house. Many of these hakka houses have places to store rice and other food stores, stables for animals to be locked up at night and the land around them was terraced for agriculture.
