Prefabricated House with Full Renovation

The renovation of prefabricated houses with full renovation packages requires a comprehensive consideration of the characteristics of modular buildings and the risks associated with full renovation packages. Prefabricated houses (modular buildings) are constructed by prefabricating building modules (including ceilings, floors, water and electricity pipelines, etc.) in factories and assembling them on-site. They offer advantages such as short construction periods, controllable quality, and energy efficiency. However, during the renovation process, it is still necessary to be vigilant against common tactics used in traditional full renovation packages and optimize the construction plan based on their structural characteristics.

I. Core Characteristics of Prefabricated House Renovation
The renovation of prefabricated houses needs to be closely integrated with the factory prefabrication process. For example, water and electricity pipelines are usually pre-embedded in the modules in the factory, and only the connection of interfaces is required after on-site assembly. It is necessary to confirm the quantity and location of points in the design drawings in advance to avoid additional costs later. For basic renovation materials such as walls and floors, products that match the module materials can be selected, such as lightweight partition boards suitable for light steel keel walls, to reduce damage to the structure caused by on-site processing. In addition, modular buildings have high requirements for airtightness, and special attention should be paid to checking the waterproof and moisture-proof treatment of doors, windows, and joints during renovation to avoid a decrease in airtightness due to improper construction.

II. Common Risks and Countermeasures in Full Renovation Packages

1. Low-price traps and additional costs: Some renovation companies attract customers with low prices and later increase costs by adding 'non-standard items' (such as module joint reinforcement and special material treatment). Countermeasure: Require the contract to clearly state 'special clauses for prefabricated houses', list all possible additional items and their unit prices, and agree on a total price fluctuation range (such as no more than 5%).
2. Substandard materials: The contract vaguely describes material brands and specifications (such as only stating 'environmentally friendly paint'), and low-cost substitutes are actually used. Countermeasure: Specify material brands, models, and environmental protection levels (such as E0-grade panels), and require the provision of material arrival inspection reports. If necessary, commission a third-party inspection.
3. Water and electricity renovation tricks: The water and electricity pipelines in prefabricated houses are already pre-embedded, and renovation companies may charge extra fees on the grounds of 'insufficient points'. Countermeasure: Confirm the pipeline layout diagram with the factory in advance, clarify the number of points to be added, and fix the total price in the contract.

III. Inspiration from the Upgrading of Overseas Market Demand
In 2026, China's prefabricated building exports will shift towards permanent buildings such as high-end residences and senior living apartments, and overseas customers will have higher requirements for renovation quality. For example, data center projects need to meet special requirements such as anti-static and constant temperature and humidity, while star-rated hotel projects focus on details such as acoustics and lighting. Domestic renovation companies can learn from such experiences and develop standardized renovation packages for prefabricated houses, while also providing personalized customization services (such as smart home integration and aging-friendly renovations) to enhance market competitiveness.
