unifamiliar

Unifamiliar, or vivienda unifamiliar, is a dwelling designed for a single family, distinct from housing designed for multiple households. In architectural and real estate contexts, the term denotes a single‑family dwelling, typically intended to be occupied by one household and separated from other units by private space and access. The concept is common in Spanish- and Portuguese-speaking regions and corresponds to the English term single‑family dwelling.

There are two main subtypes commonly described in planning and construction terminology: unifamiliar aislada and unifamiliar adosada. Unifamiliar aislada refers to a detached house that stands alone with surrounding private space, while unifamiliar adosada refers to an attached single-family unit, such as a townhouse or row house, sharing one or more walls with neighboring units.

Typical characteristics include a private entrance, dedicated outdoor space (such as a yard or garden), and a self-contained utility and service provision. Designs vary widely by region and climate, ranging from one-story cottages to two- or more-story family homes. Construction materials and stylistic choices reflect local traditions, availability of resources, and energy considerations.

Urban planning and economics influence unifamiliares through zoning and land use policies that promote or restrict single-family dwellings. Critics argue that a prevalence of unifamiliares can contribute to urban sprawl and higher land consumption, while proponents highlight privacy, autonomy, and potential for personal customization and capital value.

Contemporary trends include smaller footprints, sustainable and energy-efficient features, infill development, and the use of prefabricated components, all within a framework that balances individual needs with community planning.
