Prefabricated Houses and a Non-standard Term in Construction

"Prefabricated houses" is a professional concept in the construction field, while "daozhi" is not a term in construction, so the following focuses on introducing prefabricated houses:

Definition and Types

Prefabricated houses are a form of construction where major building components such as walls, floors, and roofs are manufactured in a factory and then transported to the construction site for assembly. There are several types of this construction form, including modular homes, which divide a house into multiple standard modules produced in the factory and then transported to the site for assembly; prefabricated panel houses, which are built using prefabricated floor and wall panels; container houses, which are modified and assembled based on shipping containers; and wooden prefabricated houses, where the main components are prefabricated from wood in the factory.

Advantages

• Rapid Construction and Shortened Project Duration: Since most components are prefabricated in the factory, only assembly is required on-site, shortening the construction period by more than 50% compared to traditional construction. For example, a 100-square-meter prefabricated house can be completed in 1-2 months, while a traditional brick-and-mortar house takes more than 6 months.
• Cost Control: Factory production optimizes material and labor costs, and standardized production reduces material waste. Modular design reduces the complexity of on-site construction. The construction cost of an ordinary prefabricated house ranges from 1,000 to 3,000 yuan per square meter, far lower than the over 5,000 yuan per square meter for traditional high-end houses.
• Environmental Protection and Energy Efficiency: Factory production reduces dust, noise, and waste pollution from on-site construction. Many prefabricated houses use recyclable materials such as light steel and wood, and some high-end prefabricated houses also integrate solar panels, insulation materials, and intelligent energy-saving systems to reduce energy consumption.
• Flexibility and Portability: Modular design allows for customization of house layouts according to user needs and can be disassembled and reassembled at other locations in the future. Container houses and light steel structure houses are suitable for scenarios requiring frequent relocation, such as tourist homestays and construction site dormitories.
• Quality Control: The factory production environment is strict, and components are manufactured under controlled conditions, ensuring better quality.

History

Prefabricated houses have a long history, with prefabricated buildings appearing as early as the 17th century. During the American colonial period, settlers assembled houses using prefabricated wooden structures. After World War II, the demand for damaged houses in participating countries surged, leading to rapid development of prefabricated buildings, which were widely used for post-war housing reconstruction.
