Interior Renovation of Prefabricated Panel Houses

Interior renovation of prefabricated panel houses can be carried out through methods such as space optimization and improvement of lighting and ventilation, but special attention must be paid to structural safety and the assessment of the current condition of the house.

1. Space Optimization Renovation

The load-bearing structure of a prefabricated panel house is usually composed of prefabricated panels and load-bearing walls. During renovation, it can be considered to change some load-bearing walls into beam-column structures to expand the interior space. For example, by breaking through non-load-bearing walls on the first floor or reinforcing them with steel structures, originally separated small rooms can be transformed into open workshops or large functional areas. It should be noted that: Before renovation, a professional structural engineer must evaluate the load-bearing capacity of the house to avoid structural instability caused by the removal of load-bearing walls. If the house is an old prefabricated panel house, some walls may simultaneously bear loads and have seismic resistance functions, so their removal should be carried out with caution.

2. Improvement of Lighting and Ventilation

Prefabricated panel houses often suffer from insufficient lighting and poor ventilation due to small window areas and closed layouts. During renovation, targeted optimizations can be made. For example, large-area windows or glass doors can be added to non-load-bearing exterior walls to introduce natural light; air circulation can be improved by installing fresh air systems or optimizing the design of door and window airflow. Key point: If the house has problems with darkness and dampness, the waterproof layers of the roof and exterior walls should be checked simultaneously to avoid exacerbating the damp environment due to leakage.

3. Floor and Foundation Treatment

Some suggest that during the renovation of prefabricated panel houses, the floor should be left as untouched as possible, mainly based on two considerations: First, the connection between the prefabricated panels and the floor may involve hidden structures (such as ground beams), and random modifications may damage the overall stability; second, the floors of old houses may have settlement or cracks. Directly covering new flooring (such as wooden floors or tiles) can conceal these problems, but it is necessary to ensure that the base is flat and dry. If floor renovation is required, it is recommended to first carry out structural reinforcement or leveling correction and then lay new materials.

4. Safety Risks and Limitations

Prefabricated panel houses generally have problems such as poor thermal insulation, weak sound insulation, and a limited design lifespan. Some houses may even become dangerous buildings due to long-term disrepair. Before renovation, the structural safety of the house must be tested by a professional institution to confirm whether it meets the renovation conditions. It is especially important to note that: If the house is identified as a dangerous building, reinforcement or reconstruction should be carried out first, rather than just interior decoration, otherwise potential safety hazards may be left.

Renovation should balance functional requirements with structural safety, prioritize solving existing defects of the house (such as leakage and cracks), and then consider upgrading space and aesthetics.
