Daiwa House Domestic Prefab Houses

Daiwa House has prefab house-related businesses in China, with mature prefabricated assembled residential technology that has been applied in some projects.

I. Technical Characteristics of Prefabricated Assembled Residential Buildings
The prefabricated assembled residential buildings (Prefab House) of Daiwa House Industry Co., Ltd. adopt a modular production method, achieving efficient construction through factory-prefabricated components and rapid on-site assembly. Its core advantage lies in an extremely short construction period; in typical cases, the main structure can be completed in just 5 days. This technology significantly reduces on-site wet work through standardized design, industrial production, and assembled construction, minimizing the impact of weather on the construction schedule while enhancing construction accuracy and quality stability.

II. Domestic Prefab House Product Line
Daiwa House has launched a "Small House" product line tailored to domestic market demands, primarily featuring compact 40㎡ units that precisely target single urban households or small-scale living scenarios. This product has a prefabrication rate of over 90%, meaning that core components such as walls, floor slabs, and stairs are all prefabricated in the factory and only require on-site connection and fixation. This not only ensures uniform component quality but also reduces costs through large-scale production. Additionally, the modular design supports flexible combinations, allowing space expansion or functional layout adjustments according to user needs.

III. Domestic Market Application and Project Practices
Daiwa House promotes the implementation of prefab house technology through its subsidiaries in China (covering more than ten cities including Beijing, Shanghai, and Suzhou). For example, although the Hefeng Yaxin project in Suzhou is not explicitly labeled as a prefabricated assembled residential building, it won the "2025 Human Habitat Dream 'Good House'" award, indirectly reflecting Daiwa House's pursuit of high-quality and efficient construction in the domestic residential market. Combining its experience in Japan, it can be inferred that Daiwa House may integrate prefabrication technology into some high-end projects, enhancing building performance and living experience through industrial means.

IV. Technological Extension and Industry Impact
Daiwa House's prefabrication technology is not only applied in the residential sector but also extends to emerging fields such as logistics facilities and environmental protection energy, demonstrating the versatility of its modular construction system. Against the backdrop of China's "dual carbon" goals, the energy-saving and emission-reduction advantages of prefabricated assembled residential buildings (such as reducing construction waste and energy consumption) align with Daiwa House's technological accumulation, providing support for its further expansion in the domestic market.
