Housing in Anini reflects a transition from traditional indigenous architecture to modern construction. Traditionally, Idu Mishmi houses are longhouses constructed entirely of locally sourced bamboo, wood, cane, and thatch, elevated on stilts to protect against dampness, snakes, and insects.
In the main town of Anini, most contemporary buildings are constructed with timber or concrete walls and brightly colored corrugated galvanized iron (CGI) sheet roofs. These steep-pitched roofs are necessary to handle the heavy monsoon rains and occasional winter snow. The town features dedicated government residential quarters for officials, teachers, and medical staff. Affordable housing is generally self-built, supported by various state and central rural housing schemes.
