adosadas

Adosadas is a term used in Spanish-speaking contexts to describe a type of housing where one or more dwelling units share one or more walls with adjacent units, forming a row or block. A unit called a vivienda adosada is typically attached to its neighbors on the sides, with private access and often small front or back outdoor spaces. In common English architectural terminology, adosadas are closest to townhouses, row houses, or semi-detached houses, depending on the degree of attachment.

Construction and layout can vary by country and development, but adosadas generally emphasize land and space efficiency. End units may have two exposed facades, while middle units share walls on both sides. Private outdoor areas, such as gardens or courtyards, are usually smaller than those of detached houses. In many regions, adosadas are part of planned residential developments or urbanizations, with uniform exterior design and shared plot boundaries.

Advantages of adosadas include higher housing density on a given parcel of land, lower construction costs per unit, and simplified maintenance compared to detached houses. They often provide a balance between individual living space and social proximity, which can suit families and urban residents. Disadvantages can include reduced privacy and increased noise transmission through party walls, as well as potential restrictions on alterations due to shared structures or covenants within a development.

Historically, the concept arose to address urban population growth and housing demand, becoming common in Europe and Latin America in the 19th and 20th centuries and remaining widespread in modern housing estates. See also: townhouse, row house, semi-detached house, terrace housing.
