What is a Prefabricated House

A prefabricated house is a form of construction where building components are industrially produced and then assembled on-site. It is also known as a prefabricated assembled building or modular building.

From the perspective of construction mode, a prefabricated house breaks down the building into individual modules, which are manufactured in a factory and then transported to the construction site for assembly. Specifically, the ceiling, floor, plumbing, and electrical wiring of the house are all prefabricated on a factory assembly line and then assembled on-site like building blocks. This construction method breaks away from the traditional step-by-step construction process on-site and shifts a significant amount of work to a factory environment.

Prefabricated houses come in several main types. Panel-assembled: This type primarily uses prefabricated panels as the main structural or enclosure components of the building. These panels can be produced in the factory according to precise specifications and standards, ensuring consistent quality and stability. On the construction site, these panels are simply assembled and connected to quickly form the building's walls, floors, and other structures, significantly shortening the construction period. Box-assembled: Built on the basis of individual independent 'box' modules. Each 'box' module contains part of the building's functional space, such as bedrooms or bathrooms, and is completed with interior decoration and equipment installation in the factory before being transported to the site for assembly. This type of prefabricated house has a high degree of integration, enabling rapid delivery and use of the building, suitable for projects with high construction speed requirements, such as temporary housing and emergency buildings. Frame-assembled: The building's frame structure, such as beams and columns, is first fabricated in the factory and then transported to the site for assembly. The frame structure provides a stable support system for the building, and after the frame is installed, other components such as walls and floors are installed. Frame-assembled prefabricated houses combine the precision of factory production with the flexibility of on-site construction, meeting the needs of different building forms and functions.

The industrial production method of prefabricated houses makes it easier to control the quality of building components, reduces environmental pollution and noise interference on the construction site, improves construction efficiency, and shortens the construction period, making it a promising form of construction in the modern building sector.
