Efficient Construction of Prefabricated Houses
The efficient construction of prefabricated houses is primarily achieved through modular construction methods, with core elements including factory prefabrication, precise design, full-industry-chain collaboration, and technological iteration, significantly shortening construction periods, reducing costs, and expanding application scenarios.
1. Factory Prefabrication and Parallel Operations Enhance Efficiency
Modular construction breaks down houses into independent modules (such as ceilings, floors, and plumbing and electrical systems), which are prefabricated on factory assembly lines. Through automated production lines and parallel operation modes (e.g., China State Construction Hailong Industrial Park delivers 20,000 to 30,000 modules annually), construction periods are reduced by over 60% compared to traditional serial operations. Traditional construction requires sequential completion of steps like scaffolding, bricklaying, and plastering, whereas modular construction synchronously completes structural, finishing, and equipment installations in the factory, with only assembly required on-site, greatly reducing process overlaps and waiting times.
2. Precise Design and Error Control Ensure Quality
Modular construction adheres to industrial product standards in design, with every steel bar and screw precisely positioned, and errors controlled to the millimeter level. For example, the Shenzhen affordable housing project used 6,028 concrete modules for assembly, compressing the completion and delivery period from 2.5-3 years to just 1 year, and reducing on-site labor by about 50%. Precise design not only improves construction efficiency but also ensures seamless connections between modules, avoiding rework issues caused by error accumulation in traditional construction.
3. Full-Industry-Chain Collaboration and Logistics Optimization Reduce Costs
Leveraging China's full-industry-chain advantage, 'house building' is transformed into a standard industrial product for export. From design and R&D, intelligent production, to overseas logistics and installation, all links are closely integrated. For instance, 63 modules purchased by UK clients from China were installed on-site in just two weeks after shipment; 84 modules in Papua New Guinea were assembled into a fully functional hotel. Full-industry-chain collaboration reduces intermediate links, while logistics optimization shortens transportation cycles, jointly lowering overall costs.
4. Policy Support and Industrial Cluster Effects Drive Scaled Development
Regions like Fujian Province have established industrial bases through policy support, achieving over 70% reduction in construction waste. In the first four months of 2026, Guangzhou Customs' jurisdiction exported RMB 1.4 billion worth of prefabricated houses, a 38.1% year-on-year increase; Shenzhen Port exported RMB 1.68 billion, a 19.6% increase, covering over 150 countries and regions. Policy guidance and industrial cluster effects promote technology popularization and economies of scale, further enhancing the market competitiveness of prefabricated houses.
5. Technological Iteration and Scenario Expansion Broaden Application Boundaries
Prefabrication technology encompasses prefabricated concrete structures and steel structures, with components including beams, slabs, walls, and columns. Beyond residential use, modular construction has been applied to hotels, senior living apartments, dormitories, office buildings, and global data center construction (e.g., Jiangmen CIMC has delivered over 1,000 MW of installed capacity in modular prefabricated data center projects). Technological iteration and scenario expansion extend prefabricated houses from single residential functions to diversified, specialized fields, continuously releasing market potential.
Market research institutions predict that the global modular construction market will exceed USD 142.8 billion by 2030, with China continuing to explore this trillion-dollar market through efficient construction methods.
