A residential structure containing two separate living units within a single building, where each unit has four bedrooms, provides ample living space for larger families or those desiring extra room for guests, home offices, or recreational activities. These designs offer a unique opportunity to combine the benefits of multi-family living with a sense of privacy and independence for each household. One unit may be situated above or beside the other, depending on the architectural style.
Such architectural plans are often considered for maximizing land use, potentially reducing construction costs compared to building two separate single-family homes. They can foster closer familial relationships when occupied by related parties, such as parents and their adult children, while still maintaining distinct living spaces. Historically, this type of housing has served as a practical solution for accommodating multiple generations under one roof or for generating rental income.
