Cost Comparison of Prefabricated Houses

The cost comparison of prefabricated houses requires analysis from different dimensions. Their cost advantages are mainly reflected in materials, labor, construction efficiency, and maintenance, but the overall cost varies due to configuration differences.

1. Cost Comparison with Traditional Self-Built Houses
Prefabricated houses have significant cost advantages in rural settings. Taking Xiaoguan Village in Gongyi City, Henan Province as an example, a two-story, 300㎡ prefabricated villa costs a total of 250,000 yuan, saving 40% (150,000 yuan) compared to traditional brick-and-mortar structures. The core reason lies in the industrial production model:

• Material Costs: Factories purchase steel and cement on a large scale, and robotic arms control pouring errors to the millimeter level, avoiding issues such as steel bar misalignment and concrete voids on traditional construction sites, reducing rework costs.
• Labor Costs: A project in Yiyang County, Luoyang, shows that nine major functional modules complete rock wool insulation layers and pre-embedded water and electricity pipelines in the workshop, requiring only four people to assemble with a crane on-site, reducing labor costs by 80%.
• Transportation Costs: Centralized distribution models reduce transportation costs to 18 yuan per square meter.
  It should be noted that the unit price of 300 yuan/㎡ only includes the rough main body. If high-end configurations such as photovoltaic roofs and smart home systems are added, the overall cost will rise to around 600 yuan/㎡.

2. Cost Comparison with Housing Construction in Europe and the United States
Prefabricated houses offer excellent cost-effectiveness in the European and American markets. The cost of ordinary self-built houses in rural China is approximately tens to hundreds of thousands of yuan, similar to the price of prefabricated houses, so traditional self-building remains dominant. However, in European and American countries, construction workers earn daily wages of 200-500 USD and strictly adhere to an 8-hour workday, causing labor costs to account for more than 50% of the total housing construction cost. The total cost of an ordinary residential house often exceeds one million yuan, while a prefabricated house produced in China costs only 200,000 yuan. The cost advantage stems from:

• Labor Cost Differences: Prefabricated house production in China relies on industrial assembly lines, significantly reducing labor demand.
• Supply Chain Integration: Full process control from design, production, to transportation further reduces costs.

3. Cost Comparison with Ordinary Houses
Prefabricated houses have lower costs than ordinary residential houses in multiple aspects:

• Building Materials: Factory-produced prefabricated panels have high production efficiency and controllable costs; ordinary residential houses may have higher procurement costs due to a wider variety of materials.
• Construction Efficiency: Prefabricated houses have short construction periods and low labor costs; ordinary residential houses have complex construction processes, with labor costs often exceeding 30% of the total cost.
• Structural Complexity: Prefabricated houses have standardized designs and low construction difficulty; ordinary residential houses may see significant cost increases if they involve irregular structures or high-end materials.
• Post-Maintenance: Prefabricated house components are modular, with low repair and replacement costs; ordinary residential house maintenance may involve hidden projects, resulting in higher costs.
