Evolution of Prefabricated Buildings: From Building Houses Like Cars to Using AI for Construction House

With the continuous development of construction technology, the traditional construction industry is gradually transforming towards industrialized construction. Prefabricated buildings overturn traditional construction concepts by treating buildings as products and construction as manufacturing, aligning with the development direction of construction industrialization and representing an inevitable trend in the transformation and upgrading of the construction industry.

 

Wanhua Promy focuses on industrialization, greening, digitization, and intelligence, successfully developing prefabricated components such as wall systems, floor systems, integrated bathrooms, and integrated kitchens with independent intellectual property rights. It has participated in the formulation of more than 10 national and industry standards and holds over 100 national patents. Its R&D capabilities and technical level rank among the top in the country. The company's products are widely used in affordable housing, commercial housing, hotels, and other fields, with a cumulative delivered project area exceeding 10 million square meters.

 

Wanhua Promy is committed to creating healthy smart spaces and has successfully developed prefabricated spatial products for hotels, residences, offices, hospitals, schools, and other scenarios. Keeping pace with the times, it has also developed prefabricated micro-space products such as quick-install shop spaces, quick-install e-sports spaces, and quick-install laboratories.

Summary.

 

From "building houses like manufacturing cars" to "building houses with AI," prefabricated construction is rapidly evolving along the path of component standardization—system integration—assembly-based construction—digitalized delivery—intelligent operation and maintenance. Taking Wanhua Promy as an example, focusing on high-performance walls, floors, ceilings, and kitchen and bathroom modules, combined with quick-connect pipelines, robotic construction, and the Internet of Things, the space becomes a "product" that can be quickly assembled, maintained, and upgraded; Pstudio AI drives 3-second scheme generation, precise order splitting, flexible manufacturing, and robotic installation through AIGC + parametric design, connecting the design—production—delivery closed loop, and expanding prefabrication from new construction scenarios to stock renovation. This paradigm significantly shortens construction periods, reduces costs and pollution, improves quality and personalized supply, and promotes prefabrication from "component replacement" to a "platform ecosystem."

 

Looking ahead, with the improvement of open interfaces and industry standards, the popularization of digital twins and full lifecycle management, and the deepening of material recycling and module reuse, prefabrication will move towards AI-native and robot-native near-zero carbon delivery, achieving scalable replication of "platform design—flexible manufacturing—unmanned installation—intelligent operation and maintenance," reshaping the product and service logic of the construction industry.
