The resulting design solution involves a series of terraces with a gallery located directly opposite the natural exhibit. The exhibit is really a series of 13 aquariums that are linked together to simulate one continuous body of water. Exhibits accompanying each distinct area were done in a different accent color to set them apart and to further delineate the space. The character of the exhibit is very open and relates to materials used on the building's exterior. Poured concrete walls for the aquarium are natural in color and complement the artificial rocks used in the gallery.
Flooring varies throughout the space and includes carpeting, vinyl and concrete surfaces.
In a departure from earlier aquarium design, the Robins Nature Center features an extensive amount of windows. Kuttner notes that the natural light flowing into the space is augmented when necessary by incandescent light to mirror daylight. Light tracks were suspended off the fir trusses above and were also post-mounted on gallery exhibits. The education wing houses the Discovery Room and the Discovery Lab, classrooms and support areas. In the Discovery Room, older children can run simple experiments or look at specimens up close.
