 Above the granite base, the exterior is clad with brick in hues of green, gold, and buff, a material that Walker preferred for its texture and color.There is cast-stone ornamentation on the building's upper floors, as well as patterned motifs and limestone decoration on the lower floors; when possible, these features were created using the help of machines.The Verizon Building also contains serrated stone-and-light-brick parapets, which, when combined with the building's vertical piers, give a naturalistic "alpine" look to the setbacks.
