Characteristics of Prefabricated Houses
The characteristics of prefabricated houses are mainly reflected in efficient and fast construction, controllable quality, environmental protection and energy conservation, low cost, strong flexibility and mobility, and guaranteed design life.
Efficient and Fast Construction: All components of prefabricated houses are pre-fabricated in advance on factory assembly lines and can be quickly assembled on-site. For example, a modular elderly care apartment manufactured in China and purchased by a British customer had its 63 modules installed on-site in just two weeks after arrival; a 100-square-meter prefabricated house may take only 1-2 months to complete, while a traditional brick-and-mortar house may take more than six months, significantly shortening the construction period.
Controllable Quality: Factory production employs high-precision molds for standardized manufacturing, with each component undergoing strict quality control during production. The concrete strength is improved compared to traditional construction, and the seismic performance has passed a simulated seven-level earthquake test. After adopting the reinforced concrete monolithic pouring process, the seismic performance can be upgraded to an eight-level standard, ensuring the quality and safety of the house.
Environmental Protection and Energy Conservation: The production process reduces dust and noise pollution. The use of recyclable materials can reduce construction waste by 80%, with a material recycling rate of over 90%. Meanwhile, good thermal insulation performance reduces energy consumption. Some high-end prefabricated houses integrate solar panels, insulation materials, and intelligent energy-saving systems, with energy efficiency designs meeting national green building standards, aligning with the development trend of environmental protection and energy conservation.
Low Cost: Factory production reduces material waste by about 30%, shortens the construction period by 50-70%, reduces material costs by 20-40% through large-scale production, and cuts labor costs by about 60%. The construction cost of an ordinary prefabricated house is typically between 1,000 and 3,000 yuan per square meter, far lower than the cost of a traditional high-end house (over 5,000 yuan per square meter).
Strong Flexibility and Mobility: Modular design allows for customization of the house layout according to needs. In the future, it can be disassembled and reassembled at other locations. Container houses and light steel structure houses are particularly suitable for scenarios requiring frequent relocation, meeting the usage needs of different users.
Design Life: The design life of prefabricated houses is generally 30 to 40 years, and with the adoption of new technologies, the service life can be extended to 70 years. However, there are also pain points such as poor sound insulation and increased maintenance costs in the later stages.
