The Green Transformation: River Retreat’s New Eco-Friendly Roofing

Nestled in the tranquil corners of Koh Mak, the River Retreat is synonymous with relaxation and connection with nature. Yet, the retreat’s recent sustainable step has made its bond with the environment even stronger, and it deserves to be talked about.

This season, visitors to the River Retreat will be greeted with a fresh change – a brand new eco-roof that arches gracefully over the restaurant. Gone are the conventional roofing materials made from concrete slabs, replaced by the resilient and sustainable cogon grass.



Why Cogon Grass?

Cogon grass, a native to many parts of Asia, has been used for centuries in various construction practices, from roofing to wall-making. Beyond its aesthetic appeal, which lends a rustic charm to any structure, cogon grass is celebrated for its environmental benefits. Being a rapid-growing grass, it is a renewable resource, making it a preferred choice for sustainable constructions. Moreover, this grass offers excellent insulation, ensuring the interiors remain cool, reducing the reliance on artificial cooling systems.

Eco-Roofing: A Sustainable Choice

The decision to adopt cogon grass for roofing isn’t just about aesthetics or tapping into traditions; it’s a testament to River Retreat’s commitment to environmental stewardship. Eco-roofing has multiple benefits:

  1. Natural Insulation: Cogon grass provides remarkable insulation, which means during those sunny Koh Mak days, the restaurant remains pleasantly cool, reducing the energy demands of air conditioning.
  2. Durability: Despite being a natural material, cogon grass roofs are known for their durability, able to withstand the tropical rain and sun.
  3. Biodiversity Boost: Such eco-friendly initiatives often support local biodiversity. Birds, insects, and other tiny creatures find the grass roof a haven, increasing the ecological richness of the area.



A Dining Experience Under the Green Canopy

With this new roofing initiative, dining at the River Retreat’s restaurant is not just about the sumptuous dishes. It’s about relishing meals under a canopy that stands as a testament to sustainable choices. As the gentle breezes rustle through the cogon grass roof, diners are reminded of the harmonious balance between luxury and eco-consciousness.


The River Retreat in Koh Mak is setting a remarkable example of how resorts can seamlessly blend luxury with sustainability. The new cogon grass roof isn’t just a structure; it’s a philosophy, a commitment to the planet. As more establishments hopefully follow suit, the future of eco-tourism on the island looks promising and green.
