CHETDA is a versatile community and recreation center in Sam Phran, Nakhon Pathom, crafted to foster social interaction and physical well-being. The project features a strategic open-plan layout including a multipurpose outdoor plaza, a perimeter jogging track, flexible semi-outdoor spaces for seasonal markets, and dedicated facilities for music, dance, and academics. Its centerpiece is a second-floor sports complex housing four international-standard badminton courts designed with a focus on player privacy and natural ventilation. By integrating sustainable elements like solar panels, natural lighting, and universal design principles, CHETDA serves as a modern, eco-friendly "community living room" that seamlessly connects indoor activities with the surrounding neighborhood.
