Finished Prefabricated Panel House Design Drawing

Currently, there is no directly provided complete design drawing for finished prefabricated panel houses, but design ideas can be offered by referring to relevant cases.

I. Design Ideas for Small-sized Prefabricated Panel Houses Take the renovation project of a 48㎡ prefabricated panel house in the family compound of Chongqing Technology and Business University as an example. This case adopts a whole-house renovation in a natural wood style, covering core functional areas such as the living room, bathroom, kitchen, bedroom, and entrance hallway. When designing, it is essential to prioritize meeting basic living needs. For instance, an open layout can be used to enhance spatial permeability, and customized furniture can be employed to achieve functional integration (e.g., an entrance cabinet that serves both storage and shoe-changing purposes). The choice of natural wood materials not only meets environmental requirements but also softens the rigid feel of the prefabricated panel structure through natural textures, making it suitable for residents seeking a warm atmosphere.

II. Optimization Strategies for Extremely Small Spaces The renovation case of a 22㎡ prefabricated panel residence in Yangpu District, Shanghai, provides a model for designing extremely small spaces. Its core strategies include:

1. Vertical Space Utilization: Create an entrance hallway by embedding a shoe cabinet through door opening modification. In the kitchen, use high-low cabinets to distinguish between the worktop and storage area. In the bathroom, achieve dry-wet separation and reduce the size of the toilet compartment.
2. Multi-functional Furniture: Install a wall bed inside the living room cabinets. During the day, it can be folded up to free up activity space, and at night, it can be unfolded to meet sleeping needs. This design is particularly suitable for single people or small families.
3. Streamlined Circulation: Arrange all functional areas around a central corridor to reduce ineffective walking area. For example, open the kitchen worktop towards the living room to create an integrated "cooking-dining" circulation.

III. Structural Innovation in Transportable Prefabricated Houses The transportable prefabricated house project adopts a cubic modular design with dimensions of 3.9 meters in width and height and 11 meters in length. It includes a bedroom, a loft mezzanine, a kitchen, a bathroom, and a leisure area. Its design highlights are as follows:

1. Three-dimensional Layering: Increase the usable area through a loft mezzanine. Arrange public areas (such as the living room and kitchen) on the lower level and private spaces (such as the bedroom) on the upper level to achieve vertical functional zoning.
2. Spatial Permeability: Use large glass windows or transparent partitions to introduce natural light and enhance visual extension, alleviating the enclosed feel of the prefabricated panel structure.
3. Modular Combination: Each functional area is prefabricated as an independent module, facilitating transportation and on-site assembly, making it suitable for temporary housing or vacation cottages.

IV. General Design Principles When designing prefabricated panel houses, it is crucial to focus on structural safety and spatial adaptability:

1. Load Calculation: Since the load-bearing capacity of prefabricated panels is limited, avoid large-area suspended ceilings or heavy decorative materials during design. Prioritize the use of lightweight partition walls and furniture.
2. Pipeline Embedding: Embed water and electricity pipelines during the prefabrication stage to reduce the need for later trenching, which could damage the structural integrity.
3. Sound Insulation Treatment: As the sound insulation performance of prefabricated panels is relatively weak, enhance living comfort by adding sound insulation cotton or double-layer panels.
