What is the term for a habitable room intended for one family, equipped with basic living facilities?

The term "Dwelling Unit" accurately describes a habitable room or space designed for occupancy by one family, complete with essential living facilities such as a kitchen, bathroom, and sleeping area. This designation emphasizes the concept of self-containment, allowing a family to live independently within the unit. A dwelling unit fosters the notion of providing basic amenities required for daily living, making it a fundamental component in discussions of residential architecture and urban planning.

In contrast, the other options don't encapsulate this specific definition. "Low-end dwelling" and "high-end dwelling" imply a qualitative assessment of housing based on cost or luxury level rather than focusing on the concept of family occupancy or living facilities. Meanwhile, the term "residential" broadly refers to areas or classifications pertaining to housing but does not specifically denote a distinct unit for a single family. Thus, "Dwelling Unit" remains the most precise term in this context.
