Popularization of Prefabricated Component Housing
Prefabricated component housing has been gradually gaining popularity in recent years, driven by both national policies and market demand. Its core advantages, expanded application scenarios, and improved technological systems have collectively accelerated this process.
Policy-Driven: Top-Level Design Defines Development Path
The state has set a clear direction for prefabricated component housing through policy documents. For example, the State Council's '15th Five-Year Plan for Urban Renewal' promotes intelligent construction and prefabricated decoration, setting a target for prefabricated buildings to account for 40% of newly constructed urban buildings by 2030. The carbon peak implementation plan jointly released by the Ministry of Housing and Urban-Rural Development and the National Development and Reform Commission further strengthens requirements for green buildings and low-carbon development. Policy dividends have directly driven the standardization and large-scale development of the industry, laying a foundation for market popularization.
Market Demand: Urban Renewal Creates Essential Scenarios
A large number of old residential areas and dilapidated buildings in China are entering renovation cycles. Traditional construction methods face challenges such as long cycles, high noise levels, and heavy pollution, making them difficult to meet demand. Prefabricated component housing, with its modular and standardized design, enables rapid renovation of old houses,户型改造 (apartment layout modifications), and space upgrades, reducing construction periods by over 50% and causing minimal disruption to residents' lives. For instance, the significant growth in export volumes of mobile homes in Guangzhou and Shenzhen reflects strong overseas demand for efficient construction solutions.
Core Advantages: Triple Improvement in Efficiency, Environmental Protection, and Quality
- High Construction Efficiency: Prefabricated components are produced in factories to standardized specifications, allowing on-site assembly periods to be compressed by over 50% and significantly shortening project timelines.
- Green and Low-Carbon: Construction waste is reduced by 80%, and reduced wet operations result in extremely low dust and noise pollution, aligning with carbon peak targets.
- Quality Control: Overcoming the drawbacks of traditional construction's reliance on manual craftsmanship, industrialized production ensures structural safety and quality stability.
Technological Iteration: From Single Components to Modular Integration
China's prefabricated concrete technology originated in the 1950s and saw a resurgence in the 21st century due to environmental demands. Companies like Vanke have developed prefabricated shear wall residential structural systems and applied prefabricated frame technologies to enhance efficiency. Modular construction, as a more integrated model, reduces construction periods by over 60% and is widely used in overseas projects (such as temporary housing and emergency facilities), forming a new growth point for technology exports.
Application Scenarios: From Domestic Renovation to Global Markets
Prefabricated component housing now covers areas such as renovation of dilapidated buildings, old residential area upgrades, home improvement upgrades, and temporary supporting construction. In the first four months of 2026, export volumes of mobile homes in Guangzhou and Shenzhen increased by 38.1% and 19.6% year-on-year, respectively, indicating its extension from domestic to international markets. In the future, as technological costs further decrease, prefabricated component housing is expected to play a greater role in affordable housing, cultural and tourism facilities, and other sectors.
