Dimensions of Prefabricated Concrete Integrated Houses

The dimensions of prefabricated concrete integrated houses vary significantly depending on design, function, and structural form, primarily falling into two categories: standard sizes and custom sizes. When selecting, it is essential to consider factors such as purpose, site conditions, and cost.

I. Standard Sizes (Modular Design)

Standard sizes are centered around modularity, facilitating easy transportation and installation, making them suitable for rapid deployment scenarios. Common specifications include:

• Small Housing Units: 3m × 6m (18㎡), often used for temporary facilities such as construction site offices and duty rooms.
• Medium-Scale Units: 4m × 8m (32㎡), commonly found in rural self-built houses, storage facilities, or small shops.
• Larger Spaces: 5m × 10m (50㎡), suitable for family homes, community centers, or commercial properties.
• Other Specifications: 6m × 6m (36㎡), 8m × 6m (48㎡), 9m × 7m (63㎡), and 12m × 10m (120㎡), covering needs from tens to hundreds of square meters. Design Features: Modular structures shorten production cycles, reduce costs, and allow for combination and expansion to meet diverse functional requirements.

II. Custom Sizes (Flexible Adjustment)

Custom sizes are adjusted according to specific needs, offering greater flexibility:

• Width Range: Typically 3-4 meters, with fine adjustments in increments of 10 centimeters (e.g., 3.1m, 3.2m); special requirements can extend up to 7.2m or 7.6m (suitable for large storage or industrial facilities); the maximum width for single/double/triple-story houses is usually 12 meters, with lengths customized as needed (starting from 3 meters for single-story, 5 meters for double-story, and 7 meters for triple-story).
• Length Range: Flexibly adjustable, such as 6.6 meters (outer diameter), with some projects supporting even longer custom lengths.
• Other Parameters: Height, number of stories (single or double), roof form (flat or pitched), door and window types (fixed or operable), etc., can all be customized.

III. Basis for Size Selection

1. Purpose: Temporary housing (e.g., construction sites) prioritizes standard sizes to reduce costs; long-term residency or commercial use tends to favor custom sizes to match functional requirements.
2. Site Constraints: Narrow sites require precise width control (e.g., 3.1m), while open sites can accommodate larger sizes (e.g., 12m × 10m).
3. Cost and Efficiency: Standard sizes are cost-effective and quick to produce; custom sizes incur additional design fees but precisely match needs.

IV. Precautions

1. Transportation and Installation: Custom sizes require assessment of transportation feasibility (e.g., special vehicles for oversized widths) and installation conditions (e.g., lifting equipment).
2. Foundation Bearing Capacity: Large houses must ensure foundation bearing capacity meets safety standards to avoid settlement risks.
3. Prefabricated Panel Limitations: Residential prefabricated panels have a maximum span of 4.2 meters (customizable), with widths primarily at 500mm and 600mm, and common thicknesses of 120mm and 150mm. Design must coordinate structural and material parameters.
