Prefabricated Assembled Houses in Zhejiang

In Zhejiang, prefabricated assembled houses, mainly in the form of fully prefabricated rural houses, represent a new house-building model promoted in rural areas, characterized by rapid construction, diverse structures, and policy support.

Construction Methods and Efficiency

Fully prefabricated rural houses in Zhejiang utilize standardized core components (such as walls and floor slabs) prefabricated in factories, which are then quickly assembled on-site. For example, the main structure of the first model house in Yuyao City took only about 7 days to build, significantly shortening the traditional house-building cycle. The prefabricated components in Jiangbei, Ningbo, adopt a panel structure connected by mechanical bolts, ensuring both structural stability and ease of construction. Additionally, the component design incorporates sandwich insulation layers, enhancing the energy efficiency of the houses to suit Zhejiang's climatic conditions.

Structural Types and Applicability

Fully prefabricated rural houses in Zhejiang mainly include two structural types:

1. Light Steel Structure: As a key promotion direction in the national pilot province for steel-structured prefabricated residential buildings, light steel-structured rural houses offer advantages such as light weight, good earthquake resistance, and short construction periods. Demonstration communities of light steel-structured rural houses have been built in places like Lin'an District, providing replicable models for rural housing construction.
2. Concrete Shear Wall Structure: Suitable for scenarios requiring high structural strength, this type achieves a balance between efficient construction and structural safety through the assembly of prefabricated concrete components.

Policy Support and Systematic Promotion

Zhejiang Province has introduced several supportive policies to promote the popularity of prefabricated assembled houses:

• Financial Subsidies: Financial subsidies are provided to farmers or projects adopting prefabricated construction techniques to reduce house-building costs.
• House-Building Loans: Low-interest or interest-subsidized loans are offered to alleviate farmers' financial pressures and encourage the adoption of new construction technologies.
• Technical Specifications: The formulation of provincial technical guidelines provides unified standards for the design, construction, and acceptance of fully prefabricated rural houses, ensuring project quality.
• Management System: The advancement of the "Rural Houses in Zhejiang Construction Affairs" full life-cycle management system enables digital supervision throughout the entire process from planning and construction to maintenance, improving management efficiency.

Application Prospects and Significance

The promotion of prefabricated assembled houses in Zhejiang not only addresses issues such as long rural house-building cycles and inconsistent quality but also reduces construction waste and energy consumption through standardized production, aligning with green building trends. With continued policy support and technological improvements, fully prefabricated rural houses are expected to become the mainstream model for rural housing construction in Zhejiang, providing strong support for rural revitalization.
