Guangzhou Prefabricated Housing

Guangzhou has developed a comprehensive development model in the field of prefabricated housing that is technologically advanced, policy-complete, globally export-oriented, and environmentally efficient.

I. Technological Systems and Demonstration Projects Lead Industry Innovation
Guangzhou took the lead in releasing the country's first unified technical system for modular buildings, dividing buildings into four categories. Among them, the 'Composite Concrete System' has passed seismic tests and can meet the needs of high-intensity earthquake zones. The country's first 'Good Housing' demonstration project—the four-story police station office building in Huadu District, Guangzhou—uses fully prefabricated components produced in a smart factory. The on-site assembly construction period is less than one month, more than 60% shorter than that of traditional buildings. This project has verified the feasibility of modular buildings in the field of public buildings and provided a technological benchmark for large-scale applications.

II. Quality Control and Policy Support Build a Guarantee System
The Guangzhou Housing and Urban-Rural Development Bureau implements strict quality supervision: it requires assembled building projects to purchase 'Quality Latent Defect Insurance' and 'Green Building Performance Insurance' and entrusts third parties to conduct full-process risk control. It implements 'one code per item' quality traceability management for prefabricated components to ensure traceability of each part. At the policy level, it incentivizes enterprises to adopt assembled technologies through floor area ratio rewards and compresses the approval process to five working days, forming a closed-loop guarantee of 'technology-quality-policy'.

III. Industrial Scale Expansion and Outstanding Export Performance
The prefabricated housing industry in Guangzhou exhibits a global layout: in the first four months of 2023, enterprises across the country exported movable houses worth 1.68 billion yuan through the Shenzhen port, a year-on-year increase of 19.6%, covering more than 150 countries and regions. Local enterprises such as CIMC Modular Building Systems Co., Ltd. have built their exhibition centers using modular technology. Their products have achieved a 'boom' effect through promotion on overseas social media platforms and have been publicly recommended by the spokesperson of the Ministry of Foreign Affairs, demonstrating the international competitiveness of Chinese prefabricated buildings.

IV. Significant Technological Advantages and Environmental Benefits
Modular buildings achieve 70% of the processes in factories, shortening the construction period by more than 50% compared to traditional models. Solid waste emissions throughout the life cycle are reduced by 75%, and on-site workers are reduced by 70%. Moreover, factory production avoids weather interference, and the quality stability is superior to on-site construction. Taking the Huadu police station project as an example, its construction waste generation is only 30% of that of traditional projects, and energy consumption is reduced by 40%, meeting the requirements of the 'dual carbon' goals.
