Southern architecture refers to the diverse architectural styles found in the southern United States, influenced by the region's climate, history, and cultural heritage. Key styles include Colonial, Antebellum, and Victorian, often characterized by large porches, high ceilings, and expansive windows to promote airflow in the warm climate. Materials like brick, wood, and tabby (a concrete made from oyster shells) are commonly used. Notable examples include the grand plantation homes of Louisiana and the charming cottages of Charleston. This architecture reflects the region's agricultural roots and the blending of various cultural influences over time.
