There are two prototypes. One is 22.5 square meters and the other is 18 square meters. The compact design is achieved in part by transferring the kitchen and bathroom outdoors, which will be a shared system. Steel-framed and wrapped in recyclable materials, the homes have corrugated FRP panel roofs, bamboo louvers to shield against the tropical sun and a translucent polycarbonate panel wall that permits natural light to illuminate the interior. A gap between the wall and the roof evacuates hot air.
In order to save space, Vo Trong Nghia installed folding beds that can be put away during the day. Otherwise they can be used as sofas. The idea was to demonstrate the flexibility of the design, which also features adjustable longitudinal walls to accommodate expanding families. With a modest palette of sustainable materials and clever space-saving techniques, the designers have brought the cost of this construction down to approximately $3,200. Whilst perhaps still unattainable for the very poor, with government intervention, this charming home could become the new standard for low-income housing.
