The Pros and Cons of Prefabricated House Cost

The 'pros' of the cost of prefabricated houses are mainly reflected in low costs, short construction periods that save expenses, and reduced material wastage that lowers costs; the 'cons' are mainly reflected in significant price differences requiring careful selection and potential subsequent maintenance costs.

Cost Advantages

The cost of prefabricated houses is low, with a per-square-meter cost ranging from 300 to 1200 yuan, enabling significant cost savings compared to traditional construction methods. For example, in rural areas of Henan, a prefabricated house costs just over three hundred yuan per square meter, with a small villa costing between 50,000 and 100,000 yuan, and a large villa around 150,000 yuan. For the same area, the cost of prefabricated panels is approximately 60% to 70% of that of cast-in-place panels, saving enough for a thousand-yuan mobile phone per square meter. For a 200-square-meter villa, a prefabricated house can be completed for 210,000 yuan, while a brick-and-mortar house would be 28% more expensive.

The short construction period saves related expenses. Factory production can shorten the construction period by 50% to 70%. In rural areas of Henan, the main structure of a prefabricated house can be assembled in as little as two hours, with a team of workers able to assemble a villa in four hours and a building in just two days. A short construction period also reduces labor costs.

Reduced material wastage lowers costs. Factory production reduces building material wastage by approximately 30%, and mass production reduces material costs by 20% to 40%.

Cost Disadvantages

Significant price differences require careful selection. The per-square-meter price of prefabricated houses varies greatly, from 300 to 1200 yuan. The cheapest 300-yuan rough version is suitable for temporary rural housing, while a fully framed version capable of withstanding a magnitude 9 earthquake starts at 800 yuan. If the choice is not appropriate, it may not meet one's needs. For example, choosing a low-priced but poor-quality prefabricated house may lead to issues in earthquake resistance and durability.

There may be subsequent maintenance costs. Some users have reported issues with prefabricated houses, such as leaks at joints and wall cracks, with annual maintenance costs increasing by 1500 to 3000 yuan after 20 years. This undoubtedly increases long-term usage costs. When considering the cost of prefabricated houses, one should not only focus on the initial cost but also consider potential subsequent maintenance costs.
