The design and layout of the inside of a narrow, prefabricated dwelling unit, typically transported in one section, constitutes a specific area of residential architecture. Examples of design elements include efficient space utilization through multifunctional furniture and strategic placement of fixtures to maximize perceived roominess.
Efficiently designed living spaces offer a more affordable housing option, particularly in areas with high construction costs or limited land availability. Historically, these dwelling options provided accessible housing solutions and continue to evolve in terms of design aesthetics, construction materials, and technological integration, contributing to both affordability and sustainability in the housing market.
