Prefabricated House and Large Flat-Layer Residence

Prefabricated houses and large flat-layer residences are two entirely different types of housing, with significant differences in definition, structural form, functional characteristics, and other aspects.

Definition and Construction Methods
Prefabricated houses fall under the category of industrialized construction. Their core involves prefabricating building components (such as beams, slabs, walls, and columns) in factories and then transporting them to the site for assembly. The main technical systems include prefabricated concrete structures and steel structures, with types covering panel prefabrication, box prefabrication, and frame prefabrication. This construction method enables standardized production, significantly shortening the construction period and reducing construction pollution. For example, prefabricated houses produced in China have been exported in large quantities overseas, with the export value in the Guangzhou Customs area reaching 1.4 billion yuan in the first four months of 2026, a year-on-year increase of 38.1%, reflecting their industrial advantages.

Large flat-layer residences, on the other hand, are an upgraded form of traditional housing, emphasizing the flat integration of spatial functions. They are defined as single-story residences with an area exceeding 130 square meters and complete functional areas, typically adopting a "one-floor, one-household" layout that concentrates the multi-story functions of a villa (such as living, dining, and leisure) on a single plane. This design abandons vertical space division and enhances living comfort through horizontal extension.

Structural Forms and Spatial Characteristics
The structure of a prefabricated house is composed of prefabricated components connected through bolts, welding, or concrete pouring to form an overall load-bearing system. Its spatial layout is flexible but may have relatively fixed internal functional divisions due to modular design constraints.

Large flat-layer residences focus on single-story large spaces and achieve functional integration through open design. For example, the living room, dining room, and kitchen often adopt an integrated layout, while the bedroom area is relatively independent, forming a dynamic-static partition. Their sense of space emphasizes horizontal extension, enhancing transparency through large floor-to-ceiling windows and high ceilings, creating a villa-like living experience.

Functional Positioning and Application Scenarios
Prefabricated houses are mostly used in scenarios requiring rapid construction, such as temporary housing, post-disaster reconstruction, and tourist resorts, and can also serve as permanent residences. Their industrial characteristics give them advantages in cost control and environmental performance, but they have relatively limited space for personalized design.

Large flat-layer residences are positioned in the high-end housing market, targeting families pursuing a quality lifestyle. Their advantage lies in achieving efficient functional integration through single-story layouts, avoiding the vertical traffic burden of multi-story residences while retaining villa-level living facilities (such as independent walk-in closets and master bedroom suites).
