Prefabricated Housing in Jiangsu

Jiangsu has made remarkable progress in the field of prefabricated housing, leading in terms of industrial scale, technological advantages, policy support, and corporate innovation.

I. Industrial Scale and Market Applications
Leveraging its dual strengths in manufacturing and construction, Jiangsu has developed a large-scale prefabricated integrated housing industry. A leading factory in the province is equipped with fully automated production lines and a strict quality control system, achieving an annual production capacity of hundreds of thousands of square meters. Its products cover key areas such as resettlement housing, industrial parks, and emergency facilities. For example, Nanjing, as one of the first national demonstration cities for prefabricated buildings, initiated over 320 new prefabricated building projects during the 13th Five-Year Plan period, with a total construction area of 27.02 million square meters. The proportion of prefabricated buildings increased from 10.34% in 2016 to 38.72% in 2020, indicating a significant rise in market penetration.

II. Technological Features and Core Advantages
Prefabricated houses in Jiangsu are based on high-strength steel structures or concrete components, combined with BIM technology for full lifecycle management. The products boast three main characteristics:

1. Superior Performance: High earthquake resistance and excellent thermal insulation, suitable for various scenarios such as residential, educational, and medical facilities;
2. Green and Smart: Some high-end products integrate intelligent ventilation, energy-efficient lighting, and renewable energy systems, meeting green building standards;
3. Modular Design: Supports future expansion and functional adjustments to meet urban renewal needs.
   Compared to traditional cast-in-place buildings, prefabricated houses can shorten construction periods by over 30%, reduce on-site wet operations and construction waste emissions, significantly improving construction efficiency and environmental protection levels.

III. Policy Support and Regional Practices
Nanjing promotes the development of prefabricated buildings through a “categorized promotion” strategy:

1. Regional Division: The city is divided into key, active, and encouraging promotion areas, with clear differentiated development goals;
2. Source Control: Prefabricated building requirements are specified during land transfer to ensure project implementation;
3. Demonstration Leadership: Leveraging its status as a national demonstration city, Nanjing has cultivated over 320 prefabricated building projects, forming replicable experiences.

IV. Corporate Innovation and Product Applications
Enterprises in Jiangsu continue to break through technological bottlenecks:

1. Component Production: For example, GeGou Company has developed prefabricated components such as gypsum wallboards and composite floor slabs, featuring strong crack resistance and short construction periods;
2. Mode Innovation: The BanDa Space team adopted lightweight aggregate concrete prefabrication technology to complete the country's first “prefabricated rural house” in Wujin District, Changzhou, achieving 90% factory finishing and 7-day delivery with full furnishings, providing a new paradigm for rural construction.
