Leshan Prefabricated Modular Housing

Represented by modular prefabricated housing, Leshan's prefabricated housing has achieved full-chain mass production in Leshan, Sichuan, with the core R&D and production entity being Sichuan Huagou Residential Industry Co., Ltd. (a national-level prefabricated building industrial base under China National Building Material Group).

Construction Mode and Technological Advantages

Modular prefabricated housing breaks away from traditional construction logic by dividing houses into standardized modules. Complete interior finishing, including walls, floors, plumbing, electrical systems, and kitchen and bathroom fixtures, is carried out in the workshop, with only assembly required on-site. Its green and intelligent workshops employ automated production lines and intelligent robotic arms, achieving millimeter-level construction precision. Simultaneous production of multiple processes significantly enhances construction efficiency. Compared to traditional construction methods, construction periods can be shortened by 40%—60%, on-site labor reduced by half, and dust and construction waste emissions significantly decreased, aligning with trends in green building development.

Technologically, the company leverages its provincial-level prefabricated building engineering laboratory to hold multiple core patents and participate in industry standard formulation. Housing modules meet seismic resistance requirements of magnitude 8, with high-strength concrete components capable of withstanding strong typhoons, and their safety performance has passed multiple verifications. Standardized residential modules come with pre-installed doors, windows, appliances, and piping, allowing for direct occupancy with water and electricity connections upon on-site assembly, offering a convenient "move-in ready" experience.

Application Scenarios and Typical Cases

Modular building technology has been applied across various fields, including affordable housing, rural residences, public facilities, and industrial plants. For example, the fully PC-assembled Sichuan-style new Chinese courtyard house in Shoubao Town, Qianwei County, Leshan, has passed a magnitude 9 earthquake simulation test, boasting a service life of over a century and doubling construction efficiency compared to traditional methods, serving as a model for green rural housing. Additionally, this technology is suitable for scenarios such as old residential area renovations, emergency housing, and industrial park dormitories, with individual modules supporting separate disassembly and maintenance, minimizing disruption to surrounding residents during construction.

Policy Support and Market Development

The Leshan Housing and Urban-Rural Development Bureau is promoting the popularization of prefabricated buildings, requiring that by 2026, newly built government-invested housing projects have a prefabrication rate of no less than 50%, and socially invested projects no less than 30%, while facilitating the technology's expansion into county areas (e.g., increasing the proportion in Qianwei County, Jiajiang County, and Emeishan City to 58%). As of 2026, Huagou Residential Industry has implemented over 200 projects, with an industrialized construction area exceeding 10 million square meters and a market share of over 20% in southwest China, forming a product matrix covering housing construction, municipal engineering, new energy, and cultural tourism facilities. China's modular building exports are surging, with a 45% growth rate in the first quarter of 2026. Huagou Residential Industry is expanding into the "Belt and Road" market, introducing products such as prefabricated low-rise box houses and modular factories.
