Cases of Prefabricated Housing
There are numerous successful cases of prefabricated housing in different countries and regions, demonstrating its advantages of efficiency, flexibility, and environmental friendliness.
I. Large-scale Public Buildings and Residential Projects The hotel project in Papua New Guinea adopted Chinese modular construction technology, transporting 84 "giant parcels" by sea to the local site and quickly assembling them into a fully functional hotel. This model not only shortened the construction period but also attracted customers from countries such as the UK and Saudi Arabia, reflecting the competitiveness of prefabricated housing in the international market. The CIMC Modular Building's elderly care apartment project in the UK showcased the core characteristics of modular construction: prefabrication in factories followed by on-site assembly. This construction method reduced the complexity of on-site construction, improved construction efficiency, and was particularly suitable for public buildings with high requirements for construction time and quality. The public housing project in Shenzhen, Guangdong, is a typical application of prefabricated housing in high-rise residential buildings. Five residential buildings nearly 100 meters tall were assembled from 6,028 concrete modules, with a 70-square-meter two-bedroom unit requiring only two and a half modules for assembly. Compared to traditional methods, the project shortened the construction period to one year, reduced on-site labor by about 50%, and significantly reduced noise, dust, construction waste, and traffic congestion, demonstrating the environmental and efficiency advantages of prefabricated housing.
II. Low-cost Housing Solutions Prefabricated houses in Texas, USA, are priced at $50,000, while those in Australia cost approximately 61,400 yuan (12,500 Australian dollars) and cover an area of 70 square meters upon expansion, including one bedroom, one living room, one kitchen, and one bathroom. These cases indicate that prefabricated housing can reduce costs through standardized design and industrial production, providing affordable housing options for low- and middle-income groups.
III. Renovation and Maintenance of Existing Buildings The waterproof renovation project for the prefabricated panel roof of Phase I of Zhonghuan Jiayuan in Putuo District addressed common issues such as deformation and cracking of prefabricated panels by adopting a systematic renovation plan, including comprehensive obstacle removal, base layer repair, panel seam reinforcement, membrane waterproofing, and gutter strengthening. This case demonstrates that prefabricated housing technology is not only applicable to new projects but can also extend the service life of existing buildings and improve living quality through targeted renovations.
