This project is situated in the Cam Thanh area of Hoi An, Vietnam. The design team drew inspiration from the local Nipa Palms, incorporating bamboo—a material deeply rooted in Vietnamese culture—as the primary structural element. Positioned at the end of a river, the building often faces strong winds. Despite being covered with lush vegetation, natural light still filters through into the interior spaces.

Using bamboo as the main building material offers several advantages. First, the multi-layered bamboo structure effectively absorbs sound, enhancing acoustic comfort. Additionally, bamboo is a cost-effective option that provides efficient internal communication spaces. The roof is thatched, which also contributes to sound insulation.

The building’s bamboo framework is composed of 22 arch sets. Each arch group’s columns and trusses are connected through a central support system. The overall structure reaches approximately 9 meters in height and rests on a concrete foundation.

The signature arched structure reflects the form of the Nipa Palm while also enhancing the building’s durability. These arches provide resistance against horizontal forces and help protect the structure from storms common in central Vietnam. Moreover, the thatched roof combined with a layer of metal mesh shields the interior from harsh weather conditions. This project exemplifies the use of natural materials to create a long-lasting structure, a key vision of VTN Architects.
