The Georgian style of architecture originates from the English, who utilized bits and pieces of classical Greek architectural ornamentation. Many Georgian homes are square in plan, one to two stories tall and are perfectly symmetrical. Openings display classical ornamentation, such as columns and pilasters, which appear as flat arches. Windows never occur in pairs, and they are of the same quantity as those on other side of the house. The roof is hipped, meaning all sides slope down, or has a gambrel, seen most commonly on barns, with a chimney on each end of the house. A pediment, or triangular decoration glimpsed on classical columns, may be used on the second story or even over the windows. The Georgian style was incredibly popular in America in the early 19th century and is a classic example of young Americana.
