The main building features several unusual Cubist bas-reliefs commissioned by Barnes from the sculptor Jacques Lipchitz. Elements of African art decorate the exterior wrought iron and the tile work created by the Enfield Pottery and Tile Works on the front portico of the building. Barnes built his home next to the gallery, which now serves as the administration building of the Foundation. His wife, Laura Leggett Barnes, developed the Arboretum of the Barnes Foundation and its horticultural education program in 1940.
