15 years after 9/11, NYC has worked tirelessly to rebuild Lower Manhattan. The transportation hub, Oculus, opened in March. The World Trade Center Mall opened less than a month ago.

It's been a slow but worthwhile process and for the most part, the plans for the World Trade Center area haven't been fully complete until now. 

Yesterday, designs for the World Trade Center's Performing Arts Center, which is expected to open in 2020, have finally been unveiled.

Curbed reports that the Performing Arts Center has been part of the plan for a while but only as a concept.

After an intense design competition last year, the Brooklyn firm REX was chosen as the building's architect, which will be named The Ronald O. Perelman Performing Arts Center at the World Trade Center, after the donation of $75 million by billionaire Ronald Perelman.

Barbra Streisand will also be serving as The Perelman's chairwoman of the board.

According to The New York Times, The Perelman will have a distinct appearance to reflect its location next to the somber 9/11 memorial.

“The building really has a double life: During the day it has an appropriate stateliness, stone stateliness addressing the memorial,” said Joshua Prince-Ramus, the principal of REX. “Then at night it dematerializes, and the activity within starts to get revealed through the facade.”

To achieve this affect, The Perelman is gonna be wrapped in sheets of marble, so thin that they're translucent, and encased in glass– it will emanate an amber glow when the sun goes down but maintain solemnity during the day.

The design illustrates a cubical 90,000-square-foot building that hardly captures the insane plans in store; the walls of the space will be movable and they don't plan to have much of the building fixed in place.

That means capabilities we don't even really understand yet, allowing for 11 different configurations that can host both intimate shows and large concerts. 

"The more people use the building, while we hope that they will take it as their own, the more they will simply not understand how all of these varied experiences can be happening within one single structure," shares Prince-Ramus.
