Four Types of Key Prefabricated Houses
The prefabricated houses among the four types of key housing mainly include Grade D dilapidated houses, low-floor-area-ratio prefabricated panel houses in prime urban locations, prefabricated panel houses in key urban development areas, and prefabricated panel houses unable to withstand natural disasters. Details are as follows:
Grade D dilapidated houses: These prefabricated houses have serious structural damage issues such as loose foundations and cracked walls. After professional assessment, they are identified as Grade D dilapidated houses, posing significant safety hazards and requiring priority demolition. For example, in 2023, a prefabricated panel community built in 1988 in Xi'an was identified as a Grade D dilapidated house due to wall cracks exceeding 10 centimeters, leading to the emergency evacuation of 600 households. This indicates that the demolition of Grade D dilapidated houses is based on their severe structural problems and safety hazards to ensure the safety of residents' lives and property.
Low-floor-area-ratio prefabricated panel houses in prime urban locations: These areas typically have high land value. After demolition, high-rise buildings can be constructed, achieving land appreciation and bringing significant economic benefits. For example, after the demolition of some six-story prefabricated panel houses in Jing'an District, Shanghai, 30-story high-end residential buildings can be built, fully utilizing land resources and improving urban space utilization efficiency.
Prefabricated panel houses in key urban development areas: Such as areas along subway lines and new district planning areas, the transformation of these areas is crucial for urban development, so the demolition of prefabricated panel houses is imminent. For example, Chongqing plans to renovate 83,000 shantytown households by 2025, prioritizing the demolition of these prefabricated panel houses located in key development areas to promote urban renewal and development.
Prefabricated panel houses unable to withstand natural disasters: Although the main structures of these prefabricated houses are not damaged, they cannot withstand the onslaught of natural disasters such as earthquakes and floods, posing potential safety risks, and thus will also be demolished. This reflects the importance attached to the safety of residents' lives and the consideration for natural disaster prevention.
