Prefabricated buildings often transcend national borders. Builders, contractors, and designers frequently undertake projects worldwide, sharing their preferred ideas, techniques, and methods.
In the United States, high-rise residential buildings are uncommon outside of highly valuable areas like Manhattan, New York.
On May 4, 1998, President Clinton initiated the Residential Advanced Technology Joint Stock Enterprise to significantly improve housing quality across the country. The program aimed to enhance cost efficiency, durability, safety, and resistance to natural disasters.
The 1999 work plan for this initiative focused on innovating the design and production of residential components over the next decade, targeting a 50% reduction in construction time and advancing toward quality technology markets. These innovations would facilitate the production of affordable and appealing homes.
Partners in this joint venture include prominent residential builders, product and material suppliers, and academic research institutions, all collaborating to develop new technologies for the housing industry. To date, they have identified over 150 distinct technologies, many of which have been tested on-site and demonstrated nationally.
Funding from federal grants supports the development of these advanced residential technologies, continuously exploring better solutions to existing housing challenges. The Advanced Prefabricated Structure Technology Joint Stock Enterprise (PATH) also focuses on retrofitting existing homes by improving insulation and sealing to boost energy efficiency.
Importantly, one key objective of the Residential Advanced Technology Joint Stock Enterprise is to reduce monthly maintenance costs of new homes by 20%, rather than cutting the total construction cost by the same margin. This reflects a long-term strategy to optimize housing expenses. Additionally, the government offers loan guarantees to applicants with high debt-to-income ratios to improve housing affordability through non-technical measures.
The goals of each project under this initiative are detailed in organizational charts outlining objectives and actions for the coming decade. An April 1999 progress report confirmed that every activity aligns with the overall mission and specific tasks of the Residential Advanced Technology Joint Venture.
Japan’s construction industry boasts a substantial product research and development sector. By law, the six largest domestic construction firms must invest roughly 0.5% of their revenue into R&D. Each company generates billions of US dollars in annual sales, enabling significant research budgets.
Beyond legal requirements, these firms allocate additional funding to maintain a competitive edge. The combined efforts of these enterprises and government funding have positioned Japan as the world’s leading center for architectural research.
Despite advancements, many Japanese homes are still constructed on-site. For instance, almost all interior and exterior finishing (except modular bathrooms and kitchens), as well as plumbing and electrical work, are completed after installation on location.
Japan’s housing strategy focuses on transforming construction into a manufacturing process. Both government and industry collaborate on advanced building manufacturing and technological innovation. Many residences use beam and column structures or wooden frame walls, with floor modules prefabricated in factories and transported for onsite assembly. Some recent innovations incorporate manufacturing industry product technologies.
After World War II, the French government attempted to address housing shortages by constructing high-rise apartments around Paris. However, due to numerous social issues, the initiative was halted, and high-rise residential construction was stopped throughout France.
In Canada, the Ontario Department of Education began regulating school building development in 1965. Preceding this, the 1961 School Component System Development Program aimed to improve school quality while reducing planning and construction time and costs.
This open system approach places responsibility on vendors to research and develop subsystem components for building systems, while customers provide detailed specifications, performance evaluations, and ensure interoperability. Its main advantage is that manufacturers using different technologies across regions can meet the standardized specifications, allowing components from various producers to integrate seamlessly into a complete system.
Beginning around 1960, Denmark’s construction department and government collaborated to establish foundational principles for industry development, now known as Denmark’s open system approach.
This approach promotes an open market for factory-made building components that can be combined into diverse independent construction projects. The government’s role is to create a development framework, while the construction industry drives technological innovation.
Government responsibilities include setting unified national performance standards for building codes and, during the first five years, developing a long-term plan mandating that all subsidized housing adhere to modular principles and standards. This ensures the use of uniquely manufactured building components with standardized modular dimensions. Thanks to these collaborations, Denmark’s integrated decoration and construction industry capacity has tripled in less than a decade.
Current Landscape: Prefabricated Buildings Flourishing
Since the 1990s, Mainland China has developed a unique “cast-in-place concrete shear wall high-rise and super high-rise residential system” while advancing housing system reforms. After over 30 years, this system is widely used for high-rise residential projects in major cities like Beijing, Shanghai, Guangzhou, and Shenzhen, as well as smaller towns.
Meanwhile, China’s precast concrete industry has stagnated, with some regions even banning precast concrete structures. From the late 20th to early 21st century, this sector nearly vanished.
To foster diversity and innovation—”letting a hundred flowers bloom and a hundred schools of thought contend”—various building materials, structures (such as steel and wood), and construction methods must be embraced. Achieving this requires changing the uniform lifestyle patterns of the Chinese population.
Although cities like Hong Kong and Shenzhen serve as models for residential planning and design, they should be adapted thoughtfully rather than copied directly across Mainland China.
Changing Chinese living patterns is challenging, but without such change, it will remain difficult for alternative materials, structures, and construction methods to gain traction in the market.
Currently, with the reshaping of urban clusters such as Beijing-Tianjin-Hebei, the Yangtze River Delta, and the Guangdong-Hong Kong-Macao Greater Bay Area, these city clusters and bay area economies are poised to become new engines for China’s economic growth. If the competitive dynamics at the county level evolve into competition among urban clusters and bay area economies, it may pave the way for alternatives to the current high-density high-rise residential model prevalent across China.
