Small Prefabricated House Construction

Small prefabricated house construction involves the industrial production of building components and their on-site assembly to construct houses, also known as prefabricated modular construction or modular architecture.

I. Main Types and Technical Coverage Prefabricated modular construction primarily includes panel-based, box-based, and frame-based types. Panel-based construction uses prefabricated wall panels, floor slabs, and other components, which are assembled on-site to form the building structure. Box-based construction divides the building into independent modules (such as room units), with each module completing interior decoration and equipment installation in the factory. Frame-based construction focuses on prefabricated beams, columns, and other frame components, which are assembled on-site and then filled with walls. Technically, it covers prefabricated concrete structures and steel structures, with component types including prefabricated beams, slabs, walls, columns, and other products. Modular architecture further refines the process by dividing buildings into independent modules, completing integrated manufacturing of ceilings, floors, plumbing, and electrical systems in the factory, and then transporting them to the site for assembly.

II. Core Advantages

1. Short Construction Period: Industrial production and on-site assembly occur simultaneously, significantly shortening the construction cycle. For example, the completion and delivery period for a certain affordable housing project was reduced from 2.5-3 years to 1 year.
2. Controllable Quality: Standardized factory production reduces human errors, ensuring higher precision and quality stability of components compared to traditional construction methods.
3. Energy Efficiency and Environmental Protection: On-site labor is reduced by approximately 50%, significantly lowering noise, dust, construction waste, and traffic congestion, which are disruptive to local residents.
4. Easy Maintenance: Prefabricated components can reserve maintenance spaces, facilitating later equipment updates and structural maintenance.

III. Application and Development In China, prefabricated concrete technology began in the 1950s, initially applied in factory and residential construction. It regained popularity in the 21st century due to its production efficiency and environmental advantages and has been widely used in engineering projects. In overseas markets, the export of prefabricated houses from China has grown significantly. According to customs data, in the first four months of 2026, Guangzhou Customs District exported 1.4 billion yuan worth of mobile homes, a year-on-year increase of 38.1%, reflecting the rising international demand for prefabricated construction.

Prefabricated modular construction achieves efficient, precise, and green building production through industrialization and modular design, becoming an important development direction in modern architecture.
