Regional modernism

Vernacular architecture is an architectural style that is designed based on local needs, availability of construction materials and reflecting local traditions. At least originally, vernacular architecture did not use formally-schooled architects, but relied on the design skills and tradition of local builders. However, since the late 19th century many professional architects have worked in versions of this style.

It tends to evolve over time to reflect the environmental, cultural, technological, economic, and historical context in which it exists. While often difficult to reconcile with regulatory and popular demands of the five factors mentioned, this kind of architecture still plays a role in architecture and design, especially in local branches.

Vernacular architecture can be contrasted against polite architecture which is characterized by stylistic elements of design intentionally incorporated for aesthetic purposes which go beyond a building's functional requirements. This article also covers the term traditional architecture, which exists somewhere between the two extremes yet still is based upon authentic themes.

The term is derived from the Latin vernaculus, meaning "domestic, native, indigenous"; from verna, meaning "native slave" or "home-born slave". The word probably derives from an older Etruscan word.

In linguistics, vernacular refers to language use particular to a time, place or group. In architecture, it refers to that type of architecture which is indigenous to a specific time or place (not imported or copied from elsewhere). It is most often applied to residential buildings.
