Cost of Cement Board Prefabricated Houses

The cost of cement board prefabricated houses is approximately over 300 RMB per square meter. For a 200-300 square meter villa, the total cost ranges from 100,000 to 250,000 RMB, saving 30%-50% compared to traditional brick-and-concrete structures. The cost advantages and considerations are as follows:

I. Sources of Cost Advantages

1. Compression of Material and Labor Costs
   Factories achieve millimeter-level construction accuracy through large-scale procurement of steel and cement, combined with robotic pouring technology, reducing on-site wet work by over 80% and cutting labor costs by 80%. For example, in the Luoyang Yiyang County project, pre-embedded rock wool insulation and electrical and plumbing lines in the workshop allowed assembly on-site with just four workers and a crane, significantly reducing labor and material waste.

2. Optimization of Transportation and Quality Control Costs
   Although individual components weigh over 3 tons, centralized distribution reduces freight costs to 18 RMB per square meter. Factories use ultrasonic flaw detection technology to eliminate issues such as misaligned steel bars and concrete voids, avoiding rework costs common on traditional construction sites and further reducing hidden costs.

3. Lower Lifecycle Costs
   Modern cement houses are designed for a service life of at least 50 years. The energy efficiency of sandwich insulation composite wall structures is 30%-50% higher than that of traditional brick walls, resulting in significantly lower long-term maintenance costs than traditional buildings. For example, their insulation performance reduces winter heating energy consumption, lowering long-term operating expenses.

II. Factors Affecting Cost Variations

• Renovation and Equipment Upgrades: The quoted price of 300 RMB/㎡ typically includes only the bare shell. If solar roofs, smart home systems, etc., are added, the comprehensive cost can rise to around 600 RMB/㎡.
• Geological Constraints: Caution is advised in areas with soft soil. In 2024, a project in Kaifeng experienced wall misalignment due to foundation settlement, increasing repair costs.
• Environmental Adaptability Risks: Grouting materials at module joints may accelerate aging in humid and hot environments. A project in Zhengzhou experienced seepage at joints after five years, requiring regular maintenance.

III. Purchase Recommendations

• Qualification Verification: Prioritize factories holding the "Prefabricated Concrete Component Production Qualification" to ensure compliance.
• Inspection Report Validation: Request third-party compressive strength inspection reports to confirm component strength meets standards.
• Acceptance Record Review: Check local housing and construction bureau acceptance records to avoid issues arising from non-compliant construction.
