Chettinad architecture is characterized by spacious, multi-generational homes designed for extended families, featuring numerous courtyards that provide light and ventilation while maintaining cool indoor temperatures. These homes traditionally consist of raised platforms (thinnai) for entertaining guests, intricately carved doors, and specific areas designated for men and women, reflecting cultural practices and social organization within the Chettiar community. The architectural style incorporates a blend of local and imported materials, ensuring harmony with the environment and showcasing the rich cultural heritage of the region.
