CHON is a two-story retirement house located in Phanat Nikhom, Chonburi, planned to embrace tropical architecture while meeting the specific needs of elderly residents. Spanning 130 square meters, the home prioritizes thermal comfort and functionality. Large openings on all sides ensure natural airflow, while high ceilings under a gable roof enhance ventilation, maintaining a cool interior without air conditioning. Natural materials such as wood for interiors and stone for the exterior create a measured connection with the surrounding environment, further reducing heat and enhancing comfort.
