Copper meets limestone on the columns of Irving Convention Center Station. "Ben Carpenter loved the land, and he wanted Las Colinas to honor it by having simple, elegant design and quality materials," said Phillip Shore, station artist. The columns are in an interlocking pattern of oxidized red-brown copper – alluding to the exterior cladding of the Irving Convention Center itself – and split-faced limestone. The patterns of the two materials signify a "coming together," such as what happens at conventions. Windscreens are conceptually similar to the ones at Las Colinas Urban Center Station, with a translucence that allows the viewer to superimpose the artistic images on the surrounding scene. Landscaping picks up on this cue, with abundant natural prairie grasses.
