Millbrook is a well-preserved example of the style of farmsteads that were once typical in Nottoway County and the Southside region during the 19th century. The ca-1840 main house features Federal and Greek Revival architectural elements and retains its original fireplace mantels, stairways, and floors. The 110-acre Millbrook property also includes a grouping of restored and reconstructed 19th-century agricultural outbuildings—a dairy, smokehouse, kitchen, and hay barn—and known and potential archaeological resources that are important in telling the story of the area’s 19th-century settlement and development.
