Changes proposed to make Oklahoma City skyscraper tallest in US

California architecture studio AO and developer Matteson Capital have announced plans to change the height of a proposed Oklahoma City supertall skyscraper, which would make it the tallest building in the US if approved.

AO and Matteson Capital announced in a joint statement that they plan to request a variance from Oklahoma City to increase the height of the supertall skyscraper from its original proposed 1,750 feet (533 metres) to 1,907 feet (581 metres).

"Matteson Capital and AO announced today that they will request a variance from the City of Oklahoma City to increase the height for one of the towers in the already entitled development known as The Boardwalk at Bricktown," claimed the team.

"If approved, the height variance will make the structure the tallest building in the United States and currently fifth tallest in the world."

The extra 157 feet (47 metres) proposed for the skyscraper would bring it to 1907 feet tall (581 metres), a homage to the year that Oklahoma was granted statehood. Newly released renderings show a definitive spire rising from the top of the structure.

The Boardwalk at Bricktown is a mixed-used development encompassing three approved 345-foot-tall (105 metre-tall) towers and a fourth supertall skyscraper, with its originally proposed height still pending approval.

If approved, it would unseat the 1,776-foot-tall (541 metres) SOM-designed One World Trade Center in New York as the tallest building in the US and the Western Hemisphere.

100 condominiums and a 350-key Hyatt hotel are planned for Legends Tower, with a top floor that will consist of an observatory, bar and restaurant.

At approximately 5 million square feet, The Boardwalk at Bricktown is a "mixed-use marvel" and will include hotels, condominiums, retail and commercial space and "1,776 residential units ranging from market-rate to affordable workforce and luxury options", according to the team.

Renderings of the development show three geometric buildings clustered closely around the base of a skyscraper which tapers along its height to end in a bisected top.

Other towers currently being built around the US are included in this round-up of eight upcoming skyscrapers in the United States, while Fraser & Partners recently unveiled designs for what may be the world's tallest hybrid timber tower in Perth.
