A town planner and architect, Oubre has practiced architecture since 1976 and co-founded his own company, Architects Southwest, in 1980. The firm specializes in urbanist development in cultural architecture, and in educational and campus planning. His work throughout the Gulf South has received design recognition at the local, regional, and national levels. His current focus is on urbanist projects in Louisiana (most notably, The Village of River Ranch in Lafayette), Mississippi, Texas and Arkansas. He is popular with groups like The Audubon Society, as well as with developers, because he has shown that development costs can be minimized, and at the same time, an environmentally sensitive product can achieve the quality of life that is extremely attractive to home buyers.
