Prefabricated Building Design Solutions

For the design of prefabricated building construction, three main solutions can be considered: modular, a combination of standardization and customization, and cost-effective prefabrication:

Modular building solutions represent a core model in prefabricated construction. The fundamental logic involves breaking down the entire building into independent functional modules (such as bedrooms, kitchens, and bathrooms). These modules are then fully integrated with structures, finishes, and equipment in a factory setting before being transported to the site for assembly using standardized interfaces. For example, China's 'prefabricated houses' employ whole-house prefabrication technology, requiring only lifting and assembly on-site. This approach reduces construction time by over 60% compared to traditional methods, ensures strict control over material quality and construction precision through factory production, and minimizes environmental pollution caused by on-site wet work. The Canadian government has introduced 50 modular prefabricated house designs, covering types such as townhouses and quadplexes. By utilizing pre-approved standardized module combinations, these designs significantly shorten project approval times and accelerate housing supply. This solution is suitable for projects with high demands on construction time and environmental protection, but requires advance planning for module transportation routes and on-site lifting conditions.

The solution combining standardized modules with personalized customization is based on universal modules, meeting diverse needs through flexible combinations. For instance, prefabricated integrated houses in Shijiazhuang utilize a high-strength galvanized steel frame and fire-resistant sandwich panels to establish a standardized structural system, ensuring basic performance such as fire resistance, moisture resistance, and sound insulation. Simultaneously, they support personalized additions such as solar panels and intelligent temperature control systems, and even allow adjustments to module sizes and layouts. This model balances efficiency and flexibility, reducing costs through mass production while enhancing user experience through customized configurations. It is suitable for scenarios such as affordable housing and tourist homestays.

The cost-effective prefabricated housing construction solution requires systematic planning throughout the entire process from design to acceptance. Its theoretical framework includes:

1. Standardized design: Establish universal specifications for module dimensions and connection nodes to reduce the production of non-standard components;
2. Modular system construction: Classify module types such as structure, enclosure, and equipment, and clarify combination rules;
3. Factory manufacturing: Adopt automated production lines and lean management to reduce material waste and labor costs;
4. Supply chain management: Integrate raw material suppliers and logistics service providers to optimize inventory and transportation efficiency;
5. On-site assembly: Apply dry construction methods (such as bolt connections and sealant filling) to reduce reliance on wet work;
6. Quality control: Establish acceptance standards for each stage of module production, transportation, and installation to ensure structural safety and functionality. This solution requires adaptive adjustments based on local climate, material resources, and labor costs. For example, enhancing the seismic performance of module connection nodes in earthquake-prone areas and promoting plaster-free processes in water-scarce regions.
