Origin of Prefabricated Modular Housing
The origin of prefabricated modular housing is difficult to pinpoint to a specific location, as its development was driven by technological progress and industrial demand. However, the practices of early industrialized countries such as the UK and the US in the late 19th to early 20th centuries laid the foundation for it.
The concept of prefabricated modular housing stems from the pursuit of industrialization and standardization in construction. Its core lies in improving construction efficiency and reducing costs through factory-prefabricated components and on-site assembly. This model was not the invention of a single country but rather a product of technological accumulation and the context of the Industrial Revolution across multiple nations.
The UK was one of the early practitioners of industrialized prefabricated buildings. In the mid-to-late 19th century, the UK experienced accelerated urbanization due to the Industrial Revolution, leading to a surge in housing demand. To address the housing needs of workers, engineers like Joseph Paxton showcased the "Crystal Palace" at the 1851 Great Exhibition in London. Constructed using standardized iron components and glass modules for rapid assembly, although not a residential building, it embodied the concept of prefabrication. Subsequently, British companies began producing wooden prefabricated houses for use in colonies or remote areas. For example, the "Albert Cottage," designed in 1887 for Australian immigrants, was assembled on-site from components shipped by sea, becoming a typical example of early modular housing.
The US emerged as a significant promoter of prefabricated housing in the early 20th century. In 1908, Sears, Roebuck and Co. introduced "Catalog Homes," offering standardized wooden house kits that included all components and instructions. Customers could obtain these kits through mail order and assemble them themselves. This model quickly gained popularity, and by 1940, Sears had sold approximately 70,000 prefabricated houses across the US. Additionally, after World War II, the US大力发展 (vigorously developed) mobile homes to address housing shortages, further driving the standardization and scale of modular technology.
Technological diffusion and global development. In the mid-20th century, advancements in materials science (such as steel and concrete) and transportation technologies led to a gradual transition of prefabricated modular housing from wooden structures to steel-concrete structures, with applications expanding from temporary housing to permanent buildings. Nordic countries (such as Sweden and Finland) developed modular housing with high thermal insulation performance due to their harsh climates, while Japan developed prefabricated component systems with excellent earthquake resistance in response to frequent earthquakes. Today, prefabricated modular housing has become an important branch of the global construction industry. Although its origin is difficult to define, the early practices of the UK and the US laid the key foundation for its technological evolution and industrial standardization.
