Harpeth Hall School is located in the residential Green Hills neighborhood of Nashville. The nucleus of the campus is Souby Hall, which is the administration building and is the original structure present when the land was purchased. Souby Hall has been extensively remodeled, but retains its original classic facade. As of 2016, there are 11 additional buildings including the upper school complex, a middle school, a library, a gymnasium, a theater, a gallery, a mathematics and science center, a visual arts center, a center for arts and athletics, a track and soccer complex, and an athletic and wellness center. The school has a field house, an eight lane track and two softball fields. In 2007, the school installed AstroTurf, a synthetic playing surface which is used for soccer and lacrosse, a first for a girls school in Tennessee.
