In the world of construction and real estate development, tracking the movement of construction material prices is paramount, as it directly impacts project costs and investor profits. This article will delve into the construction material price situation in Q1 2025, specifically focusing on categories experiencing sharp increases like sanitary ware and tiles. We will also analyze the underlying factors and the potential impact on property appraisal or even machinery appraisal in large-scale projects. Understanding this overview will help both developers and investors plan and make smart decisions, especially when relying on specialized property appraisal companies.
Q1/2025 Figures Revealed: Sanitary Ware Jumps 9.5%
According to data from the Real Estate Information Center (REIC) and Government Housing Bank (GHB), the
sanitary ware category saw the highest price increase in Q1 2025 compared to the same period last year (YoY), soaring by 9.5%. This was followed by the
tile category, which rose by 8.6%, demonstrating the notable upward trend of these two categories within overall construction materials.
Contrasting Trends: Steel and Wood Prices Decline
While sanitary ware and tiles experienced sharp price increases, other key material categories showed completely different trends. Notably, the
steel and steel products category, a major component in large-scale construction, saw the largest price decrease, down by -7.9% (YoY). Additionally,
wood and wood products also saw a slight decrease of -0.4% (YoY). This volatility highlights the complexity of the construction material market, where prices do not move uniformly. The continuous decline in steel prices, both globally and in Thailand, is attributed to the prolonged real estate crisis in China, despite government stimulus measures. Meanwhile, the slight drop in wood and wood product prices is due to the slowdown in the domestic real estate sector.
Analyzing the Underlying Factors: From Oil Prices to Housing Repair Demand
Changes in construction material prices do not occur without reason. The REIC report points to several key factors impacting overall costs:
- Diesel Prices: The increase in prices for various construction material categories is partly a result of diesel prices remaining higher than the previous year, which impacts raw material costs, production, and transportation.
- Increased Material Demand: There is still an increased demand for construction materials for repairing homes damaged by recent floods or other natural disasters.
These factors are crucial for developers and investors to monitor closely for effective procurement planning and cost management.

Impact on Property Appraisal and Construction Cost Control
The volatility of construction material prices has a direct and significant impact on the real estate industry, particularly in two key dimensions:
- Project Cost Calculation: Unexpected changes in material prices can drive up project construction costs beyond initial estimates, affecting cash flow and project profitability. Developers, therefore, need accurate cost estimations and effective risk management.
- Property Appraisal: Property appraisal for various purposes, whether for loan applications, buying/selling, or investment, requires referencing the latest construction material price data to ensure the appraised value is accurate and current. This may also include machinery appraisal for essential components in industrial or complex systems projects. Having accurate and up-to-date material price information is crucial for property appraisal companies to provide reliable services.
Frequently Asked Questions (FAQ)
Q1: What was the overall standard home construction cost index in Q1 2025?
A1: The overall standard home construction cost index in Q1 2025 was 140.2 points. This represents an increase of 0.2% compared to the previous quarter (QoQ) and a 2.0% increase compared to the same period last year (YoY).
Q2: How much does the decrease in steel prices help reduce overall home construction costs?
A2: Although steel and steel product prices decreased by -7.9% (YoY), the impact on overall home construction costs depends on the proportion of steel used in the structure and other components of the house. Compared to other materials like sanitary ware and tiles, whose prices increased, the decrease in steel prices might offer some cost relief, but could be offset by the rising prices of other materials, potentially keeping overall costs stable or higher.
Q3: Why is property appraisal by a specialized property appraisal company important when material prices fluctuate? A3: When material prices fluctuate, property appraisal by a specialized property appraisal company is crucial because they have access to accurate and current material price data. They can precisely analyze the impact of material price changes on property values and provide advice on managing construction cost risks. This helps investors and property owners make confident and market-appropriate decisions.
Conclusion
The construction material price situation in Q1 2025 shows noticeable volatility, particularly with sharp increases in sanitary ware and tile prices, contrasting with declining steel prices. Factors such as energy costs and demand for home repairs all influence the overall market. Understanding these movements is essential for effective project planning and cost management to ensure successful investments and valuable returns. Consulting a specialized property appraisal company, especially regarding property appraisal and machinery appraisal, will provide you with accurate, in-depth information for decision-making in a changing market.
