New Prefabricated Building Materials Integrated Housing

New prefabricated building materials integrated housing is a form of construction that involves industrial production of building components and on-site assembly. It is also known as prefabricated assembled buildings or modular buildings. The following is an introduction from five aspects: construction methods, technical types, advantages, application scenarios, and technical challenges.

Construction Methods: New prefabricated building materials integrated housing breaks down the building into independent modules, which are manufactured in factories, covering ceilings, floors, water and electricity pipelines, etc. These modules are then transported to the construction site and assembled, similar to 'building with blocks'. For example, a public housing project in Shenzhen, Guangdong, was assembled from 6,028 concrete modules, reducing the construction period for five residential buildings nearly 100 meters high from 2.5 - 3 years to 1 year.

Technical Types: It includes prefabricated concrete structures and steel structures, with components such as beams, slabs, walls, and columns being prefabricated products. Some projects adopt steel-concrete composite structures, increasing steel usage by 40% compared to traditional reinforced concrete structures, resulting in stronger load-bearing capacity and seismic performance.

Advantages:

• Short Construction Period: The construction cycle can be shortened by more than 60%. For example, the main structure of a rural self-built house can be completed in 14 days.
• Environmental Protection and Energy Efficiency: Construction waste is reduced by more than 70%, and issues such as on-site noise, dust, and traffic congestion are significantly reduced.
• Controllable Quality: Module production uses high-precision positioning with millimeter-level errors. Each component has a detailed 'ID card' containing information such as project name, model, and production date.
• Flexible Design: Assembly line production supports adjustments to the house layout at any time.

Application Scenarios:

• Residential Construction: For example, the prefabricated shear wall residential structural system developed by Vanke Group and the pre-stressed prefabricated concrete assembled integral frame structural system used in the Nanjing Jindi Yufang project.
• Overseas Projects: Chinese prefabricated houses are in high demand overseas. In the first four months of 2026, the export value of movable houses from the Guangzhou Customs area reached 1.4 billion yuan, a year-on-year increase of 38.1%.
• Public Housing: A project in Shenzhen achieved rapid delivery through modular assembly, reducing on-site labor by about 50%.

Technical Challenges: It requires support from technical systems, production systems, and industrial clusters, and has high requirements for transportation and lifting equipment, such as box-type prefabrication.
