510 East St. Julian Street, also known as the Odingsells House, is a building in Savannah, Georgia, United States. It is located in the northwestern civic block of Washington Square and was built in 1797. Built as a home for Major Charles Odingsells, a native of South Carolina, it is now part of the Savannah Historic District and is the oldest building in Washington Square. In a survey for Historic Savannah Foundation, Mary Lane Morrison found the building to be of significant status. It is a one-storey gable-ended building finished in clapboard. It has a Federal-style center hall, which is flanked by a duo of sash windows. The house's stoop and steps lead up beyond a low basement. A porch was added in the 20th century. This home, and the nearby Hampton Lillibridge House, were restored by Jim Williams.
