Wooden Prefabricated Panel House

Wooden prefabricated panel houses are a type of prefabricated housing that uses wood as the main load-bearing system, combined with prefabricated component technology. They are characterized by diverse structures, eco-friendly materials, and a wide range of application scenarios.

Structural Types and Process Characteristics

Wooden prefabricated houses come in three main forms:

1. Beam-Column Structure: Utilizing solid wood or glulam for beams, columns, and purlins, connected with metal fasteners or traditional mortise-and-tenon joints, this type is suitable for religious buildings, residential structures, and other scenarios. Its advantage lies in strong structural stability and the ability to bear significant loads.
2. Light Wood Frame Structure: Composed of small-section dimension lumber densely connected to form a load-bearing system, this structure offers both flexibility and cost-effectiveness, commonly found in North American residences and some large buildings. It enables efficient construction through standardized components, resulting in lower costs.
3. Structural Insulated Panels (SIPs): These use composite panels that integrate load-bearing and insulation functions, representing high-performance wall materials. Their core advantage is integrated design, which significantly enhances building energy efficiency and reduces construction steps.
   In terms of materials, modern technology has enabled new materials like glulam to break through traditional limitations, allowing small-sized wood to be synthesized into large-span components, expanding the range of applications. Connection techniques combine metal fasteners with traditional mortise-and-tenon joints, balancing strength and aesthetics.

Application Scenarios and Market Status

In traditional fields, ancient Chinese wooden structures developed three major systems—post-and-lintel, column-and-tie, and log-wall—renowned for their earthquake resistance, as exemplified by the saying "the walls may fall, but the house remains intact." Modern applications focus on low-rise residences, tourist B&Bs, leisure farms, and other scenarios, such as trendy wooden cabins and integrated houses. With mature technologies in Europe, America, and Japan, the domestic market is gradually emerging, with prices varying based on materials, scale, and functionality: simple assembled rural wooden houses start at around ¥298.0, customized decorated wooden villas at approximately ¥1,299.99, and exported custom mobile wooden houses can reach ¥2,500.0 per square meter.

Technological Advantages and Development Trends

Wooden prefabricated houses align with trends toward industrialization, digitization, and automation, shortening construction periods through modular design. Some products support rapid assembly, meeting demands in tourist attractions and temporary housing. At the policy level, China currently focuses on repairing and renovating prefabricated houses, only demolishing those deemed unsafe, while the potential of wood as a renewable building material is being re-evaluated, especially in low-rise residential construction, where its environmental friendliness and sustainability have become key development priorities.
