These circular Hakka apartments are located in the rural province of Fujian and Yongding in China. The buildings are definitely a wonder for the eye with their doughnut-shaped architecture.
The buildings (that are home to up to 80 families at a given time) were recently granted 'World Heritage' status by the UNESCO. The Hakka apartments not only house many people, but also house important cultural values tied to the native residents' identity.
Implications - Their circular shape is unlike what most are accustomed to in the Western world; people typically build houses that are cubic in their structure. However, the round courtyards that these homes produce encourage family and community interaction.
