Cox’s Bazar is celebrated not only for having the world’s longest unbroken sea beach but also for its natural beauty, folk culture, and eco-friendly way of life. One of the region’s most distinctive features is the use of chhon—a tall, dry grass that has been an integral part of local architecture and livelihoods for generations.
What is Chhon?
Chhon is a variety of tall grass that grows in the hilly regions and lowlands of the area. Once harvested, it is thoroughly dried in the sun before use. Its primary purpose is for roofing houses, covering betel-leaf plantations, and making natural fences. Light, durable, and resistant to decay, chhon is both sustainable and highly practical, offering natural heat insulation for homes.
Tradition Meets Necessity
The use of chhon is most prominent in the hilly and rural areas of Ramu, Teknaf, Maheshkhali, and Ukhiya. For generations, locals have relied on it to thatch their rooftops. Its application in building betel-leaf shades is also a common sight, providing a cost-effective and long-lasting solution for farmers.
Local craftsman, Md. Shahabuddin explains, “Roofs thatched with chhon keep homes cooler. If built properly, they last four to five years. They are much healthier and more comfortable compared to tin or plastic sheets.”
The Bamboo–Chhon Duo
Bamboo and chhon go hand in hand in traditional architecture. Bamboo is used for the house frame, fencing, and roof structure, while chhon is layered on top to complete the shelter.
An elderly resident recalls,
“We grew up in bamboo-and-chhon houses. Back then, you couldn’t even imagine a home without these two things.”
Eco-Friendly and Economical
At a time when plastic pollution and environmental concerns dominate global discussions, Cox’s Bazar’s chhon-based architecture stands as a model for sustainable development. Since chhon is locally available and affordable, it supports a small but vital rural economy involving harvesting, drying, selling, and house construction.
Preservation and Future Potential
Urbanization has reduced the availability of chhon, but locals are making efforts to preserve the tradition. With the growing interest in eco-friendly and natural building materials, chhon has the potential to play a role in future development projects.
Structures made from natural materials are environmentally sound and carry deep cultural significance.
