Barnes’s serene modernism of solid cubic blocks and walled courtyards established a strong precedent for quality architecture in the Arts District, one that has been upheld since its founding. A long interior, north-to-south promenade orders galleries and services to each side. Perpendicular to the center of the promenade, a tall barrel-vaulted entrance pavilion faces the axis of Flora Street like a monumental arch, a visual anchor that has remained effective over the years. To the south of the gallery blocks, tall walls enclose a series of sculpture gardens by Dan Kiley. A north addition (Hamon Building) of 1993 provided a new north entrance, which is being further enhanced (2016, Studio Outside and David Hocker) with public services and improved access to Kyle Warren Park to the north.
