HOK Architects drew inspiration from classic transit halls including Grand Central Terminal in New York along with the elegance of local airship hangars. At the same time, they developed an innovative design concept that uses a parabolic form, diagrid structural system of diamond-shaped steel arches infilled with translucent ETFE, and freestanding curtain walls.

The vault-shaped building also uses advanced mechanical systems to optimize energy efficiency, like inflated ETFE cushions that cast a soft, translucent light throughout the great hall and additional frit pattern on the outer layer reduces solar heat gain. The new rail station is naturally ventilated via operable louvers and the change in height from the lower south end up to the north side.

When it comes to public facilities the building also offers a lot, including: transit-oriented retail, Wi-Fi and charging stations, parking, bike racks, lockers, community space and specialty dining.
