Built in 1807 on land acquired by Joseph Buller near Prairie Ronde in St. Landry Parish, Buller House is a Creole style house with a steep-pitched hipped roof and a large front porch that help protect the home from hot sun and heavy rains. The house has no hallways, includes a center fireplace, and is organized around a large room flanked by smaller bedrooms. Creole architecture differs from classic Cajun architecture, whose roofs have gable ends and exterior stairs leading to an attic residence, while Creole homes may use hipped roofs and have no exterior stairs. At the rear, a wide porch called a loggia separates two rooms called cabinets, which are open on three sides for cooling cross ventilation and were often used as sleeping quarters; cabinets are characteristic of Creole architecture, though some Cajun homes also include them. In southwest Louisiana, sometimes called Acadiana or New Acadia, many French-speaking Catholic immigrants who came directly from France to serve in the military or take advantage of Spanish land grants identified themselves as Creole to distinguish themselves from Acadian refugees and from the English-speaking Protestant Americans who began moving to Louisiana after 1803, when the United States acquired the territory.
