130-Square-Meter Prefabricated Panel House
The following is information about a 130-square-meter prefabricated panel house:
Structure and Cost: A 130-square-meter brick-and-prefabricated-panel house has a total cost for the foundation, main structure, and roof of approximately over 800 yuan per square meter. This price includes the labor costs for indoor and outdoor plastering and indoor tile laying. This cost level reflects the basic cost composition of building a house with a prefabricated panel structure in the current market environment, providing a reference for users with relevant needs.
Existing Problems: Prefabricated panel houses generally have some inherent defects. Weak earthquake resistance is one of the prominent issues. Due to the relatively simple connection method between prefabricated panels, the overall structural integrity is poor under external forces such as earthquakes, making it prone to damage. Poor sound insulation and thermal insulation performance is also a common problem. The material and structural characteristics of prefabricated panels make it difficult to effectively block the transmission of sound and heat, affecting the comfort of living. In addition, the service life of prefabricated panel houses is generally around 30 - 50 years. As time goes by, the house structure may experience aging and damage.
Policies and Handling Methods: The Ministry of Housing and Urban-Rural Development has not issued a unified regulation requiring the comprehensive demolition of prefabricated panel buildings. Instead, it conducts classified handling according to actual situations. Among the existing prefabricated panel houses nationwide, only about 15% need to be demolished, and the remaining 85% have a basically stable structure. They can be safely lived in through renovation measures such as reinforcement, pipeline replacement, and the addition of thermal insulation layers. The houses that will truly be included in the demolition scope mainly fall into three categories: D-grade dilapidated houses identified by professional institutions, which have severely damaged structures and can no longer meet safe living requirements; houses located within the scope of major urban planning, which need to be demolished for urban development; and dilapidated panel houses in disaster-prone areas such as earthquake zones and flood-prone areas, which pose significant safety hazards. Since 2022, China has implemented the old-community renovation policy, focusing on the repair and renovation of prefabricated panel houses and only demolishing buildings that meet the standards for dilapidated houses.
