Creole architecture in the United States is present in buildings in Louisiana and elsewhere in the South, and also in the U.S. associated territories of Puerto Rico and the U.S. Virgin Islands.The style is popularly thought to have evolved from French and Spanish colonial house forms, although historians are uncertain about its origins.[2] In Kentucky, a few scattered cottages still stand in the state's far western Jackson Purchase region, where they continued to be built into the early twentieth century.Two common secondary characteristics of this style are a raised basement and the frequent situating of the front of the buildings at the property line.[4] In the city of New Orleans, the term Creole cottage tends to be more narrowly defined as a 1+1⁄2-story house with a gabled roof, the ridge of which is parallel to the street.
