Hunan Prefabricated Modular Housing

Hunan has formed a multi-dimensional development pattern in the field of prefabricated modular housing, encompassing corporate practices, technical standards, industrial scale, and technological innovation, with significant advantages and market potential.

Corporate Practices and Outstanding Overseas Project Achievements

Jinlinjia, a subsidiary of Hunan Construction Investment Group and a leading enterprise in the province's prefabricated building industry chain, has completed the first phase of an Indonesian dormitory project using steel-structure modular technology. The project, with a total construction area of 6,897 square meters, can accommodate 500 people and was installed in just two months from the arrival of goods at the port, reducing the construction period by 90% compared to local traditional methods. Currently, its business covers 12 countries and over 30 cities worldwide, with a total installed area exceeding 300,000 square meters. In 2025, the contract value for overseas projects reached 36.6571 million yuan, with an expected breakthrough of 50 million yuan in 2026, demonstrating strong competitiveness in 'engineering going global.'

Technical Standards and Atlases Promote Standardized Development

The Hunan Provincial Housing and Urban-Rural Development Department has released two standard atlases for prefabricated green rural housing:

• Concrete Modular Structure: Suitable for sites with good road conditions and on-site lifting space, it adopts a 'few specifications, multiple combinations' design, unifying component specifications and joint processes, adapting to industrialized mass production, and enabling the main structure to be erected in just a few days, effectively reducing costs.
• Concrete Wall Panel Structure: Facilitates transportation and installation, with lower road requirements, further expanding application scenarios.
  These two atlases, based on the actual conditions of rural areas in Hunan, provide technical support for the standardized and large-scale production of modular housing.

Industrial Scale Supports Market Expansion

The construction industry in Hunan is an important pillar industry, with a total output value of 7.4 trillion yuan during the '14th Five-Year Plan' period, expected to reach 1.53 trillion yuan by 2025, and absorbing nearly 3 million people in employment annually. It is predicted that by 2030, the global market size for modular construction will exceed 142.8 billion US dollars (approximately in the trillion yuan RMB range). Hunan enterprises are transitioning from 'engineering going global' to 'standard export,' seizing trillion-level market opportunities.

Typical Cases Highlight Technological Efficiency Advantages

Broad Group has completed a 16-story residential building in Abu Dhabi, UAE, composed of 259 modular units, with the hoisting completed in just 96 hours, fully meeting local high standards. In Changsha, Hunan, a modular building assembly speed of '29 hours for 11 floors' was achieved, highlighting the leading position in technological efficiency and industrialized construction.
