Prefabricated House Finished Product Size Drawing

No information on the size drawings of prefabricated house finished products has been found, but size references for prefabricated panels and self-built houses are available

The size drawings of prefabricated house finished products usually need to be customized according to specific design requirements. Currently, no standardized size drawings of finished products are available in public information. However, the common sizes of prefabricated components and self-built houses can serve as design references. The following explains from the two dimensions of prefabricated panels and self-built houses:

I. Common Sizes of Prefabricated Panels
Prefabricated panels are commonly used structural components in prefabricated houses. Their sizes need to meet the requirements of transportation and installation convenience while taking into account structural strength. According to industry experience, the lengths of prefabricated panels are mostly between 3000 and 3600 millimeters, the widths are mainly 500 to 600 millimeters, and the thicknesses are divided into 120 millimeters (floor panels) and 150 millimeters (load-bearing panels) according to their uses. For example, a prefabricated panel measuring 3300 millimeters × 600 millimeters is a common floor panel specification in rural self-built houses, which can meet the span requirements of a single room and is convenient for manual handling and hoisting.

II. Typical Size Combinations of Self-Built Houses
The sizes of self-built houses need to comprehensively consider land conditions, family needs, and building regulations. Common combinations are as follows:

1. Small and Economical Type: With a width of 8 to 10 meters and a depth of 10 to 12 meters, the building area is about 80 to 120 square meters, suitable for families of 3 to 4 people. For example, a layout measuring 8 meters × 10 meters can be designed as a two-story house, with a living room, kitchen, and bathroom on the first floor and 2 to 3 bedrooms on the second floor.
2. Medium and Comfortable Type: With a width of 10 to 12 meters and a depth of 12 to 15 meters, the building area is about 150 to 200 square meters. For example, in a case measuring 10 meters × 14 meters, Style 1 has a width of 9.5 meters and a depth of 14.5 meters, with a building area of 330 square meters, including 5 bedrooms and an independent living room, suitable for multi-generational families.
3. Large Mansion with Courtyard Type: With a width of more than 12 meters and a depth of more than 15 meters, it is often equipped with a courtyard or ancillary buildings. For example, a layout measuring 12 meters × 15 meters can be designed as an "L"-shaped or "U"-shaped house, taking into account both living and storage functions.

III. Design Considerations

1. The sizes of prefabricated houses need to match the module sizes of prefabricated components to reduce cutting waste. For example, the lengths of prefabricated panels should preferably be integer multiples of 300 millimeters for easy alignment with walls.
2. The sizes of self-built houses need to comply with local planning requirements, such as restrictions on the area of rural homesteads and building height controls.
3. In actual design, adjustments need to be made according to functional requirements. For example, commercial houses need to reserve a relatively large width (such as 6 meters × 15 meters), while narrow-width houses (such as 5 meters × 14 meters) can optimize space utilization through vertical layouts.

If specific size drawings are required, it is recommended to contact prefabricated house manufacturers or design units to customize plans according to land conditions, functional requirements, and budgets.
