The restoration of Middleton Place began in 1916 when Middleton descendant John Julius Pringle Smith (1887–1969) and his wife Heningham began several decades of meticulously rebuilding the plantation's gardens. They had New York architect Bancel LaFarge design a stableyard complex of barn, stable, work buildings, and cottages; the buildings were constructed of brick salvaged from the ruined main house. In the early 1970s, approximately of the plantation— including the south flanker, the gardens, and several outbuildings— were placed on the National Register of Historic Places. During the same period the Middleton descendants transferred ownership of the historic district to the non-profit Middleton Place Foundation, which presently maintains the site.
