China Oceanwide Holdings has big plans for the South Street Seaport area—and now we have a sense of what they look like, thanks to a diagram dug up by NY Yimby.

80 South St will be over 1,400 feet tall—that’s 50 feet higher than the roof of 1 WTC, the Western Hemisphere’s tallest building if you count its decorative spire, which tops out at 1,776 feet.

It’s safe to say the mixed-use mega-tower will be skyline-altering. It will have the highest roof height in Lower Manhattan. An increase in the project’s air rights, which now total over 1.6M SF, helped make the staggering height possible.

Howard Hughes Corp owned the development site until selling it to China Oceanwide last year for $390M. Howard Hughes’ plans for the site went through several incarnations and faced stiff pushback from local politicians and community members.

The new design is too fresh to know much about how it’s being received in the area, but with no completion date yet announced, there should be plenty of time for neighbors to make noise about it.

The tower joins a rapidly expanding roster of supertall (higher than 1,000 feet) towers in Lower Manhattan. They include projects like 125 Greenwich St and 45 Broad St, two residential towers in the development pipeline. [NYY]
