Monolithic Prefabricated Housing

Monolithic prefabricated housing is a prefabricated assembly-type building form where building components are industrially produced in factories and assembled on-site, offering advantages such as shortened construction periods, cost savings, and high efficiency and environmental protection.

Technical Characteristics and Structural Types

Monolithic prefabricated housing encompasses prefabricated concrete structures and steel structures, with core components including prefabricated products such as beams, slabs, walls, and columns. For example, composite slabs are formed by combining prefabricated slabs with cast-in-place reinforced concrete layers, serving both as structural components and permanent formwork. They are suitable for high-rise buildings and large-span structures, with spans reaching up to 4-9 meters. Installation efficiency is enhanced through techniques such as reserved notches and intelligent formwork-placing robots, while also reducing construction waste. Additionally, modular construction is a typical representative, where buildings are disassembled into independent modules (such as ceilings, floors, and plumbing systems), prefabricated on factory assembly lines, and then assembled on-site. The construction period is shortened by more than 60% compared to traditional buildings.

Efficient Production and Construction Period Advantages

This model achieves efficient production through parallel operations, automated production lines, and intelligent management. For example, a public housing project in Shenzhen, Guangdong, utilized 6,028 concrete modules for assembly, reducing the construction period from 2.5-3 years to 1 year and decreasing on-site labor by approximately 50%. Factory-prefabricated cement houses employ a monolithic casting and forming process, eliminating the need for secondary plastering and further shortening the construction period while reducing costs.

Application Scenarios and Policy Support

Monolithic prefabricated housing has been widely applied in residential buildings, factories, and overseas projects. For instance, the Nanjing Jindi Yufang project adopted a prestressed prefabricated concrete assembled integral frame structure system. In the first four months of 2026, the export value of movable houses in the Guangzhou Customs district reached 1.4 billion yuan, a year-on-year increase of 38.1%. At the policy level, Fujian Province has promoted industrial development by establishing industrial bases, reducing construction waste by more than 70% and demonstrating the dual improvement of environmental protection and economic benefits.

Typical Cases and Data Support

The efficiency of modular construction is particularly prominent in large-scale projects. Taking the Shenzhen public housing project as an example, modular assembly not only shortened the construction period but also reduced quality risks through standardized production. Furthermore, precision control in factory-prefabricated components (such as composite slab span errors of less than 2 millimeters) and the application of automated production lines further ensure building quality and construction efficiency.
