Cost Standard for Prefabricated Houses in Tibet
The cost standard for prefabricated houses in Tibet varies depending on the type and requirements, as detailed below:
The cost of integrated houses is related to their area, number of floors, and functional requirements. For a single-story, economical integrated house with an area of 30-50 square meters, the cost is approximately 1200-1800 yuan/square meter, including basic decoration (such as wall and floor treatment, door and window installation, etc.). For a two-story, standard integrated house with an area of 60-100 square meters, the cost is approximately 1500-2200 yuan/square meter, which, in addition to basic decoration, also includes the installation of water and electricity lines and kitchen and bathroom facilities. If special functions are required, such as insulation layers (to adapt to the low temperatures on the plateau), wind-resistant designs (to cope with strong winds), or oxygen supply systems (to alleviate altitude sickness), the overall cost will be 30%-50% higher than that of similar houses in inland areas, primarily due to the higher requirements for material performance and construction techniques in the plateau environment. For example, insulation materials with lower thermal conductivity coefficients need to be selected, and oxygen supply systems require professional equipment and safe operation.
The cost of folding houses is significantly influenced by their functional configurations. In the Lhasa area, the cost of folding houses typically ranges from 800 yuan to 3000 yuan/square meter. Low-end models only have basic living functions, such as simple walls and basic doors and windows. Mid-to-high-end models enhance living comfort by increasing the thickness of insulation layers (to improve thermal insulation performance), integrating solar power supply systems (to solve electricity problems in remote areas), or incorporating sealed designs suitable for the plateau environment (to prevent sand and dust intrusion). These upgrades significantly increase costs. For example, an integrated solar power supply system requires equipment such as photovoltaic panels and inverters, and sealed designs require special sealing materials and techniques.
For prefabricated buildings, specific pricing quotas need to be referenced. The 2025 "Pricing Quotas for Construction Projects in the Tibet Autonomous Region" cover prefabricated steel structure projects, prefabricated concrete structure projects, etc. The cost standards need to be determined based on project classification and units of measurement. For example, the quota number for steel trusses is ga0001, with the unit of measurement being tons. The specific cost needs to be calculated based on project details (such as span and load) and construction requirements (such as welding techniques and corrosion protection treatments). Other prefabricated components (such as prefabricated wall panels and floor slabs) also need to be calculated based on the project codes and measurement rules in the quotas.
