There was a short-lived plan to add 11 floors to the Empire State Building.

Shortly after the World Trade Center towers were erected in the early 1970s, an architect at the firm Shreve, Lamb and Harmon concocted a scheme that would allow the Empire State Building to keep its crown as the world’s tallest skyscraper. The proposed plan called for the building’s 16-story tower to be demolished and replaced by a new top section that would increase its height to 113 stories and 1,495 feet. If completed, the renovation would have made the Empire Building taller than both the World Trade Center and the Sears Tower—which was then under construction—but the idea was quickly dropped due to cost concerns and complaints that it would destroy the building’s iconic look.
