The second tallest building in US from AO Architecture

California-based architectural studio AO is making waves with ambitious plans for a supertall skyscraper that could redefine Oklahoma City's skyline. The proposed structure, part of the Boardwalk at Bricktown development, aims to be the second-tallest building in the United States.

The envisioned development, spanning a three-acre site in downtown Oklahoma City, boasts three 345-foot-tall towers and a potential centerpiece – a towering structure reaching heights of up to 1,750 feet.

While the smaller towers have secured approval, the fate of the supertall tower still hangs in the balance, pending further approvals. If given the green light, it would stand just 26 feet shy of the iconic One World Trade Center in New York, currently the tallest building in the US.
