Prefabricated Assembled Housing in Kaifeng City
The development of prefabricated assembled housing in Kaifeng City is mature, with significant advantages in industrial scale, policy support, project application, and housing characteristics.
Industrial Scale and Enterprise Distribution: Kaifeng City has 132 above-scale intelligent construction enterprises, covering the entire industrial chain including building materials and commercial concrete. The Jinming Industrial Park in Gulou District has formed a specialized park for prefabricated buildings, gathering multiple intelligent construction enterprises. The Urban-Rural Integration Demonstration Zone has brought together 8 component manufacturing enterprises with an annual production capacity exceeding 1.2 million cubic meters, covering the entire eastern Henan region and forming a large-scale production capacity.
Comprehensive Policy Support System: Henan Province has issued policy documents such as the 'Implementation Opinions on Vigorously Developing Prefabricated Buildings', clarifying support measures such as land use guarantees, planning permits, and project approvals. Kaifeng City has further refined its policies, such as the 'Notice on Further Clarifying Measures to Support the Development of Prefabricated Buildings', providing full-process support from land use, approval, supervision to environmental protection, offering policy guarantees for industrial development.
Extensive and In-depth Project Applications: In 2026, the proportion of newly started prefabricated buildings in Kaifeng City reached 42.7%, an increase of 15.3 percentage points from 2023, with a mandatory adoption rate of 100% for three types of projects: affordable housing, schools, and hospitals. There are currently 29 projects under construction or planned, covering three major types: residential, public buildings, and industrial parks. For example, the Bian****·Yun**** residential project adopts an assembled monolithic shear wall structure with a叠合楼板 (laminated floor slab) application rate of ≥70%; the Kai**** Shi**** public building project has a prefabrication rate exceeding 55%; the Kai**** Zhi**** industrial park project features a roof with an assembled truss + photovoltaic integrated system, reflecting a green and low-carbon orientation.
Outstanding Housing Characteristics and Advantages: Prefabricated assembled housing involves prefabricating components such as wall panels, floor slabs, and stairs in factories, with on-site assembly resembling 'building blocks', resulting in extremely fast construction speeds. In Henan, it takes only 4 hours to hoist a complete house, with costs as low as over 300 yuan per square meter, and the construction cost of a 200-square-meter rough house is approximately 60,000 yuan. The housing has a lifespan of 70 years, is widely applicable, meeting the needs of residences, dormitories, office buildings, etc., and can be built up to 5 stories high, combining economy and practicality.
