Despite rapidly growing economy in Vietnam, many families are still living in very poor conditions in Mekong Delta. Many structures are damaged because of land subsidence and the intolerantly harsh tropical weather. With the given situation, the aim of the project is to provide stable but lightweight, permanent but affordable homes for low-income dwellers. The first phase of the project started in 2012 with a steel frame prototype. Since 2013, in pursuit of higher stability and comfort, a new prototype with precast concrete frame is designed and constructed in Long An Province.
Prefabrication helps control quality and cost, and future mass production. Precast concrete frame and foundation guarantee predetermined stability and accuracy. The lightweight structure allows smaller foundation and transportability by small boats, since waterways are still the dominant transportation in Mekong Delta. Finishing materials like nipa palm leaves are sourced locally and assembled by dwellers and local workers all within the budget of US$4000 per house.
