100% Prefabricated Housing

100% prefabricated housing refers to a construction model where all or most building components are manufactured in a factory and then transported to the site for assembly. It is also known as modular construction or prefabricated construction.

Core Construction Process
This model breaks down the building into independent modules, with all components such as ceilings, floors, and plumbing and electrical systems prefabricated in the factory. For example, a public housing project in Shenzhen, Guangdong, used 6,028 concrete modules for assembly, reducing the construction period for five nearly 100-meter-high residential buildings from 2.5-3 years to just 1 year, while reducing on-site labor by about 50%. Factories employ parallel operations and automated production lines, cutting construction time by over 60% and reducing on-site noise, dust, and construction waste.

Technical Types and Components
Prefabricated housing technologies include prefabricated concrete structures and steel structures, with components such as beams, slabs, walls, and columns being prefabricated products. Standardized production in factories ensures component precision, with concrete module dimensional errors controlled to within millimeters, avoiding quality fluctuations seen in traditional construction. Pre-embedded plumbing and electrical systems further reduce on-site trenching work, enhancing construction efficiency.

Advantages and Policy Support
Compared to traditional construction methods, prefabricated housing offers advantages such as shorter construction periods, controlled quality, and energy efficiency. Factory-based production reduces reliance on weather and on-site conditions, cutting construction time by over 60% and reducing material waste by about 30%. At the policy level, Guangzhou has mandated that 100% of residential land parcels auctioned from 2026 onwards will implement prefabricated construction, promoting the model from pilot projects to widespread adoption across the city and all types of commercial housing. In the market, China's prefabricated housing exports have grown significantly, with Guangzhou Customs reporting RMB 1.4 billion in activity house exports in the first four months of 2026, a 38.1% year-on-year increase, reflecting growing international demand for standardized construction.

Application Scenarios and Cases
Prefabricated housing is widely used in public housing, commercial housing, and temporary buildings. For example, a project in Shenzhen achieved the construction of a 100-meter-high building in one year through modular construction, reducing on-site labor by 50% and construction waste by 70%. Additionally, steel-structured prefabricated housing performs exceptionally well in earthquake-prone areas, with its lightweight design reducing foundation costs and making it suitable for complex geological conditions.
