Prefabricated Building House

Prefabricated building houses are a form of construction that utilizes industrialized production of building components, which are then assembled on-site. They are also known as prefabricated assembled buildings or modular buildings. Their core characteristics and advantages are as follows:

I. Technical System and Construction Mode
Prefabricated building houses are broken down into independent modules and standardized production is completed in factories. Component types include beams, slabs, walls, columns, etc., and the technical systems encompass prefabricated concrete structures and steel structures. Taking a public housing project in Shenzhen, Guangdong as an example, 6,028 concrete modules underwent all processes such as ceiling, floor, and water and electricity pipeline installations in the factory before being transported to the site for assembly. A 70-square-meter unit only requires two and a half modules for assembly. This mode transfers the wet construction work (such as concrete pouring) that is typically done on-site in traditional construction to the factory, achieving the goal of 'building houses like making cars'.

II. Core Advantages

1. Significantly shortened construction period: The construction cycle can be reduced by more than 60%. The annual delivery capacity of the China Construction HaiLong Intelligent Construction Industrial Park reaches 20,000 to 30,000 modules. The public housing project in Shenzhen shortened the completion and delivery time from 2.5 to 3 years to 1 year through modular technology, and the on-site labor force was reduced by about 50%.
2. Outstanding environmental protection and energy-saving effects: Construction waste is reduced by more than 70%, while also reducing on-site noise, dust, and traffic congestion that disturb residents. Factory production further reduces resource waste through precise ingredient mixing and recycling systems.
3. Highly controllable quality: Each component is equipped with an 'ID card' that records information such as the project name, product model, and production date. The positioning error of steel bars is controlled in millimeters. Standardized operations in the factory environment avoid quality fluctuations in traditional construction.
4. Strong scene adaptability: It can be applied to a variety of scenarios such as high-end office buildings, hotels, schools, and data centers. Its market covers more than 20 countries and regions including the United Kingdom and Australia, demonstrating its technical versatility and economic viability.

III. Development History and Market Prospects
China's prefabricated concrete technology began in the 1950s and was initially used for factory and residential construction. It experienced a resurgence in the 21st century due to production efficiency and environmental protection needs. Companies such as Vanke Group have developed prefabricated shear wall residential structural systems and promoted prefabricated frame technology. Chinese prefabricated houses have gained increasing recognition in overseas markets due to their rapid delivery and environmental protection advantages. In the first four months of 2026, the export value of movable houses in the Guangzhou Customs area reached 1.4 billion yuan, a year-on-year increase of 38.1%, indicating international competitiveness.
