Wenzhou Prefabricated Housing

Wenzhou prefabricated housing has defects but also has special cases and faces policy renovation requirements.

Defects of Prefabricated Housing

Prefabricated panel houses in Wenzhou have numerous issues. Poor seismic performance is a major concern. In the event of natural disasters such as earthquakes, their structures find it difficult to effectively withstand the impact of seismic waves, potentially posing a serious threat to the lives of occupants. Inadequate fire resistance is another problem. Once a fire breaks out, the flames can spread rapidly, and the houses have a relatively short fire-resistant time, which is not conducive to personnel evacuation and firefighting operations. Severe structural aging occurs as the service life increases. The structures of prefabricated panel houses will suffer varying degrees of damage, such as cracks and deformations, affecting the overall stability and safety of the houses. Comprehensive backwardness in living quality is evident, with poor performance in sound insulation, heat insulation, and ventilation, failing to meet modern people's requirements for living comfort.

Policy Renovation Requirements

The "15th Five-Year Plan for Urban Renewal" issued by the State Council in May 2026 has put forward clear renovation requirements for prefabricated housing. The plan clearly states that it is necessary to establish files and dynamically update them for urban C- and D-grade dangerous housing and non-complete housing, and accelerate the demolition and renovation of D-grade dangerous housing. Over the next five years, more than 500,000 sets (rooms) of C- and D-grade dangerous housing and prefabricated panel houses in urban and county built-up areas will be renovated, basically eliminating the safety hazards of D-grade dangerous housing that has been filed. For prefabricated panel houses, classified disposal will be carried out. D-grade dilapidated houses with prominent safety hazards and no reinforcement value will be demolished at an accelerated pace to improve the safety and living quality of urban housing.

Special Cases

Although Wenzhou prefabricated housing generally has some problems, there are also special cases. A prefabricated small villa customized by a boss in Wenzhou, Zhejiang, went viral on the Internet and received 2 million views. This prefabricated small villa is inexpensive and well-equipped, demonstrating new possibilities in the design and construction of prefabricated housing and providing certain references and insights for the development of prefabricated housing. However, this does not represent the overall situation of Wenzhou prefabricated housing.
