This is an example of Toda architecture, known as an Arsh. Two arches made of long bunches of bamboo are lashed together with cane. The arches support eleven Podh, strong poles running the length of the building. At 1ft (30cm) intervals a hoop of bamboo is lashed over the podh forming a ribcage. On this sticks are tied horizontally forming laths to which rows of thatch are lashed. More at www.naturalhomes.org/timeline.htm
