Vernacular Architecture typically responds to a building’s needs, by taking cultural and environmental context into account. Based on the region, these buildings evolve over time - using available (local) building materials and tradesman knowledge - suited to reflect the local climate and culture. These buildings also tend to respond to local architectural history.

Traditional Architecture is a term used when Vernacular Architecture becomes the status quo. Traditional Architecture also refers to cultural buildings - such as religious temples or royal palaces.

Consider Adobe Houses in New Mexico, Limestone Buildings in Jerusalem or Brownstones in Brooklyn. Those are examples of Traditional Architecture.

Other examples of Traditional Architecture: Buddhist Temples. Mosques. Gothic Cathedrals, The Forbidden City, Buckingham Palace, the United States Capitol.
