Vietnam Prefabricated House Specifications

The specifications of prefabricated houses in Vietnam vary depending on their type and purpose. The following introduces specific specifications from the perspectives of different projects and uses:

I. Specifications for Social Housing Projects Taking the social housing project in the Yanmei II Industrial Zone, Ho Chi Minh City, Vietnam, as an example, its unit area design is flexible, ranging from 34.9 to 77 square meters, which can meet the functional needs of different family sizes. The building structure adopts a combined system of prefabricated concrete slabs and steel trusses. The prefabricated concrete slabs are produced in a standardized manner in factories, ensuring the dimensional accuracy and structural strength of the components. The steel trusses, serving as the load-bearing framework for the roof, combine lightweight and high-strength characteristics. The combination of the two can effectively improve construction efficiency and reduce the difficulty of on-site operations.

II. Specifications for Rural Housing Construction Plans Rural houses in Vietnam are designed with differentiated foundations and main structures according to geographical and climatic differences:

1. Foundation Design: In the southern flood-prone areas, elevated pile foundations are used, with pile depths of at least 1.5 meters and house floors elevated by at least 1.2 meters to cope with seasonal floods. In the central typhoon-prone areas, integral raft foundations are adopted, with burial depths of at least 1 meter to enhance the overall wind resistance of the structure. In the northern mountainous areas, anti-landslide anchor points are used, with three anchor rods driven 2 meters deep at the edge of the foundation to prevent the impact of landslides on the house.
2. Main Structure: Priority is given to steel-bamboo hybrid structures. The main framework uses lightweight galvanized steel, balancing strength and corrosion resistance. The load-bearing part of the wall uses bamboo mat with coconut fiber boards that have been treated for corrosion and fire resistance, utilizing local renewable materials while meeting structural safety requirements. The floor height is designed with 3.2 meters for the first floor and 2.8 meters for the second floor to accommodate rural living and storage needs. The roof adopts a double-pitched gable roof with a slope of 30 degrees, which is conducive to drainage and reduces the impact of typhoons.

III. Specifications for Market-Supplied Prefabricated Houses Prefabricated houses supplied in the market exhibit diverse characteristics:

1. 32-square-meter Eco-Friendly Wooden Structure Residences: Using wood as the main material, these are suitable for scenarios such as villas, cabins, garages, and beach shelters, emphasizing eco-friendliness and rapid construction.
2. Other Types of Prefabricated Houses: These include beach villas, holiday homes, farmhouses, etc. Specific specifications vary depending on the supplier and product type. For example, the area may range from 20 to 100 square meters, with structures covering light steel, wooden, or hybrid materials, and uses covering residential, tourism, agricultural storage, etc. Users can choose standardized products or customized designs according to their needs.
