The measure across the narrow side of a prefabricated dwelling, designed for transport as a single unit, typically falls within a standardized range. This dimension is a defining characteristic, influencing livable space and transport regulations. For example, this measurement often dictates the availability of suitable transport routes.
This dimension is critical to affordability, ease of transport, and suitability for smaller plots of land. Historically, the narrow design facilitated easier movement along roadways. The benefits include reduced initial cost compared to larger modular homes and greater flexibility in site selection due to size constraints.
