Old House is an unincorporated community in Jasper County, South Carolina, United States.[1] The community is located at the intersection of SC 336 and SC 462; 5miles east of Ridgeland.
The community is named after the Old House Plantation, which was settled 1740 by Daniel Heyward. The plantation included a tidal mill, textile factory and an import-export business, all of which were destroyed by fire in 1865. The site includes the grave of Thomas Heyward, Jr., a signer of the Declaration of Independence and of the Articles of Confederation as a representative of South Carolina.
