The architectural design concept of the Wattanyu Na Thalang Auditorium at Rajamangala University of Technology Isan emphasizes simplicity with contemporary decorations, while incorporating the local Isan identity into the interior. Terracotta work and woven fabric walls are featured prominently. The designer has created both interior and exterior elements that complement each other, with the arts and culture of the Isan region serving as the project's primary focus.
