The Michigan Consolidated Gas Building was his first skyscraper, and he used elements from this design for the original World Trade Center in New York City.

At this time, a pedestrian bridge was added over West Larned Street at the 14th floor to connect the ANR offices to Michigan Consolidated, which had relocated to the adjacent Guardian Building.

The bank occupies approximately 62,000 sq ft (5,800 m2) of the structure and has also pledged an investment totaling $85 million to the city of Detroit to accompany the transition to its new regional headquarters.

These specialized light fixtures, which Yamasaki developed with the assistance of sculptor Lee DuSell, were meant to portray the jet of blue flame often seen with gas appliances.

Yamasaki had meant the light fixtures to be a tribute to the clients, and original tenants of the building; The Michigan Consolidated Gas Company.

On at least one occasion, the sculpture was the target of pranksters who painted large green footprints leading to it from The Spirit of Detroit statue across Woodward Avenue to suggest a late-night visit.
